1 Introduction

1.1 Outcomes Management Service Overview

Move to top

The Outcomes Management Service (OMS) specification is the definition of how systems manage the exchange of information that describes Outcomes. The Outcomes Management Service specification is constructed following the recommendations documented in the 1EdTech Abstract Framework (IAF) [IAF, 03a], [IAF, 03b], [IAF, 03c]. This means that this specification is based upon the concepts of:

· Interoperability – Outcomes Management Service focuses on the exchange of Outcomes information between systems. There are no definitions in the specification on how the data is managed within the systems;

· Service-oriented – Outcomes Management Service defines the exchange of information in terms of the services being supplied by the collaboration of the systems;

· Component-based – for example, the Outcomes Management Service is combined with the Group Management Service, Person Management Service, Course Management Service, Membership Management Service and Bulk Data Exchange Management Service to provide the Learning Information Services [LIS, 13a], [LIS, 13b];

· Layering – the Outcomes Management Service is a part of the Application Services layer but it interacts with the services available in the Common Services layer e.g., authentication;

· Behaviors and Data Models – the Outcomes Management Service are defined in terms of their Behaviors and data models. The Behaviors cause changes in the state of the data model and the state of the data model will only be altered as a result of a clearly defined Behavior;

· Multiple Bindings – the Outcomes Management Service information model is to be defined using the Unified Modelling Language (UML). This enables reliable mapping of the information model into a range of different bindings. The binding of immediate importance is the Web Services Description Language (WSDL);

· Adoption – whenever appropriate, the Outcomes Management Services specification makes use of other 1EdTech and non-1EdTech standards and specifications.

The logical structure of the Outcomes is composed of LineItems, Results and ResultValues. A LineItem is a collection of Results for a particular CourseOffering, CourseSection, etc. and each Result and/or LineItem may have an associated set of values, ResultValue, which are used to constrain the Result. The standard create, read, update, replace, delete and simple discovery operations are available for managing LineItems, Results and ResultValues. Other operations are defined to support specific business requirements. Full operation of all of the Behaviors in this service will require access to the data models of the corresponding 1EdTech Course Management Service (CMS) [CMS, 13] and the 1EdTech Membership Management Service (MMS) [MMS, 13] specifications.

1.2 Scope and Context

Move to top

This document is the 1EdTech Outcomes Management Services Information Model v1.0 and as such it is used as the basis for the development of the following documents:

a) 1EdTech Outcomes Management Service WSDL Binding v1.0 [OMS, 13] – the description of the WSDL binding of the Information Model.

The core uses-cases for the Outcomes Management Service are described as a subset of the Learning Information Services Specification [LIS, 13b].

This information model defines the Outcomes Management Service Abstract Application Programming Interface (a-API). The Learning Information Services specification, of which the Outcomes Management Service is a component, is a series of Behavioral models that define how the data models are to be manipulated. These Behavioral models are described using the Unified Modelling Language (UML) [SDN07, 07].

1.3 Structure of this Document

Move to top

The structure of this document is:

2. Outcomes Management Service Description	The description of the overall structure and operation of the Outcomes Management Service. This includes the description of the architectural model and the domain object model;
3. Behavioral Model	The definition of the operations of Outcomes Management Service application service. This focuses on the description of the Behaviors supported by the service;
4. Interface Data Model	The definition of the data models exchanged between the Outcomes Management Service End Systems. These are the parameters exchanged across the interoperability interface;
5. End System Data Model	The definition of the data models for the Outcomes Management Service End Systems. This addresses the persistence of the data with respect to interoperability;
6. Extending and Profiling the Service	Identification of the ways in which the Outcomes Management Service can be extended both in terms of the addition of new constituent services and proprietary extensions to a service;
Appendix A Summary List of Service Status Codes	A summary list of the status codes by for the operations of the Outcomes Management Service;
Appendix B Vocabularies	A summary of the set of vocabularies that are used within the specification;
Appendix C File-based Data Exchange	The out-of-band file exchange used in response to receiving a URL for an external data file that contains the request data.

1.4 Version Compatibility

Move to top

The Outcomes Management Service was not developed in the 1EdTech GLC Enterprise Services v1.0 specification [ES, 04]. Instead, a simplified form of functionality was supported using the 1EdTech Membership Management Services (MMS) v1.0 [MMS, 04]. In general, there is NO backwards compatibility between the usage of the OMSv1.0 and the ways in which MMSv1.0 has been implemented to support outcomes management. Vendors may define compatibility bridges for their own implementations but these are outside the scope of this specification.

2 Outcomes Management Service Description

2.1 An Abstract Representation

Move to top

It is important to remember that this document contains the description of the underlying information model in terms of the abstract API. The manner in which this abstract representation is visualized is not intended to dictate the implementation form of an Outcomes Management Service. The breakdown of the service into its interface classes is a convenient way to document the set of Behaviors. The internal organization of an implementation of the full abstract API is beyond the scope of this specification. The only constraint is that the external Behavior of the abstract API complies with this specification. This means that a .NET, J2EE, etc. physical implementation of this abstract API does not have to represent the functionality using the same breakdown of operations/methods. This physical implementation is not subject to the conformance specification.

It is important to note that the UML representation of the interfaces is used to help develop and document the Outcomes Management Service Information Model. It is not a requirement for an implementation to implement this interface as defined i.e., to use the same parameters, etc. Conformance against this specification will be confirmed by inspecting the appropriate binding of the information model and ensuring that the relevant information is present and that different sequences of activity result in the predicted and mandated Behavior. It is essential that the Behaviors described by each of the operations are fully supported and it is also essential that the Behaviors described by different sequences be also maintained.

2.2 Outcomes Management Service Architecture & Specification Model

Move to top

The basic architectural model for the Outcomes Management Service specification is shown in Figure 2.1. In this architecture the scope of the 1EdTech Outcomes Management Service specification is shown as the dotted line. The scope of the interoperability is the data and Behavioral models of the objects being exchanged.

Figure 2.1 Outcomes management service architecture model.

It is important to remember that the structure of the exchanged information has NO bearing on how the same information is contained within the ‘source’ and ‘target’ Learning Information Services systems (the Outcomes object repositories in the two end-systems). It is simply a representation of the data used to facilitate exchange between the end-systems. The only constraint on the end-system repositories is that they provide data persistence consistent with the required behavior.

2.3 Outcomes Composite Objects

Move to top

It is important to note that this is an interoperability specification and as such it makes no statements about how information is stored within the exchanging end systems. The objects in the end-systems must be persistent otherwise sequences of operation on the same object will not be possible. Reference to these objects in the interface is through a ‘sourcedId’ however this identifier does not have to be the key stored within the end-systems. If different keys are used in the end-systems then it is the responsibility of the end-systems to maintain the mapping between that key and the ‘sourcedId’ i.e., the interface must never be exposed to the keys of the end-systems.

There is no such thing as an Outcomes object. Instead, Outcomes are reflected in three types of object each of which has its own ‘sourcedId’ which are linked to create the Outcomes data model as shown in Figure 2.2.

Figure 2.2 Schematic representation of the outcomes data model.

The three classes of object are:

· LineItem – the set of results for a particular CourseTemplate, CourseOffering, CourseSection and Group (each result is a Result object);

· Result – the container for a result for a particular Person (each result can be related to a ResultValue object);

· ResultValue – the permitted range of values for a Result and/or a LineItem.

As shown in Figure 2.2 the LineItem is the key object that is used to establish the relationship between course components and the results for each person. A LineItem has three fields:

· The identifier (that is the sourcedId) of the associated course components (denoted as C_p in Figure 2.2). More than one LineItem can point to the same course component;

· The type of LineItem (this is an open vocabulary as in Figure 2.2 this includes ‘Interim’, ‘Final’, etc.);

· The ResultValue that defines the nature of all of the results associated with the LineItem (each Result must be associated with one, and only one, LineItem).

Each Result is associated with a LineItem and a Person i.e., the Person who has received the result for that particular course component. A Person may have several results, for the same or different course components, and so more than one result may be associated with a Person. The unit of marking for the Result is defined by the ResultValue associated with the Result. In general, many Results will be associated with each type of ResultValue. A ResultValue can also be assigned to a LineItem thereby defining all Results to be of the same ResultValue.

A system that wishes to support all of the behaviors of the OMS must also contain the Course data model as defined in the 1EdTech Course Management Services Information Model v1.0.1 specification [CMS, 13] and may have to support the Group data model in the 1EdTech Group Management Services Information Model v2.0.1 specification [GMS, 13].

2.4 Synchronous & Asynchronous Services

Move to top

Within the context of the Outcomes Management Service the definition of synchronous and asynchronous services is:

· Synchronous – the source service is blocked until the final response from the target service is received. A schematic representation of the information flow for a synchronous service is shown in Figure 2.3;

· Asynchronous – the source service is not blocked and so more than one request can be outstanding at any moment in time. A schematic representation of the information flow for an asynchronous service is shown in Figure 2.4.

Figure 2.3 Synchronous service action flow.

It is stressed that the abstract-API does not differentiate between synchronous and asynchronous services[1]. The support for these two approaches is differentiated at the binding level only.

Figure 2.4 Asynchronous service action flow.

The key difference is that for an asynchronous service more than one request can be issued at any one time (it should be noted that an asynchronous service can be supported using synchronous messaging). In both cases the service assumes a perfect messaging system i.e., request, response and acknowledgement messages have a guaranteed delivery grade of service.

2.5 Handling the Service Status Codes

Move to top

Each operation in a service is mapped to an appropriate message exchange pattern. Any response/acknowledgement message will contain status information. This status information provides contextual information about the completed success or otherwise of the operation. There are two types of status information that are available to the end-systems:

· Business transaction – these are the status reports that reflect the business logic of the transactions being exchanged by the end-systems. This status information will be contained within the message header under a specially defined data structure. The status information contained herein is also used to contain any error codes i.e., error reporting is handled as a subset of status information reporting;

· Messaging fault– these are fault codes that are reported by the messaging infrastructure and which are carried in the messages.

It is important to note that messaging errors may indicate that the original request never reached the service provider end-system. In this case the service consumer implementation that handles the status information is responsible for mapping the message infrastructure failure codes to the equivalent business transaction status code. The message infrastructure failure codes have no meaning with respect to an 1EdTech specification. The 1EdTech GLC specifications do not describe how the status information is to be handled within an end-system i.e., this will depend on how the abstract API is physically realized within an implementation. Therefore, it is important that an implementation can:

· Combine the transaction status information and any message fault error codes in a single integrated status reporting mechanism. Any other system failure information that is made available by an implementation should also use the same mechanism;

· Examine the status information reported after the completion of the appropriate phase of an operation and especially once the operation has been completed. This may require an explicit status information call or it may be reported as part of the API call;

· Differentiate the status information reports for each transaction within an operation. Remember that some specifications provide operations that can contain more than one transaction request and that a different status report may be given for each of those transactions.

Exception handling is the system’s response to known or unknown error conditions. Exception handling is outside the scope of an 1EdTech GLC specification. However, an error condition should not cause the end-systems to fail in an uncontrolled manner. The requirement for every operation to return status information is to enable an implementation to terminate in a controlled fashion.

3 Behavioral Model

3.1 Service Definition

Move to top

The OutcomesManagementService is used to model the service responsible for manipulating information about outcomes. The OutcomesManagementService interfaces are shown in Figures 3.1, 3.2 and 3.3. The OutcomesManagementService is split into three interfaces: LineItemManager that supports the manipulation of LineItem objects; ResultManager that supports the manipulation of Result objects; ResultValueManager that supports the manipulation of ResultValue objects.

3.2 LineItemManager Interface Description

Move to top

The LineItemManager interface class describes the operations that are permitted on LineItem objects (as shown in Figure 3.1). The set of operations are summarized in Table 3.1.

Figure 3.1 OutcomesManagementService LineItemManager interface definitions.

Table 3.1 Summary of operations for LineItemManager.

Operation	Description
createLineItem	To request the creation of a populated LineItem object on the target system where the source is responsible for the allocation of the unique SourcedId.
createByProxyLineItem	To request the creation of a populated LineItem object on the target system where the target is responsible for the allocation of the unique SourcedId.
deleteLineItem	To request the deletion of a LineItem object. The LineItem object is deleted with all of its associated relationships.
readLineItem	To read the full contents of the identified LineItem object. The target must return all of the data it has for the identified LineItem object.
readAllLineItemIds	To obtain all the SourcedIds assigned to LineItem objects.
readLineItemIdsWithLineItemType	To obtain the set of SourcedIds for the LineItem objects which have a particular state.
readLineItemIdsForPerson	To obtain the set of SourcedIds for the LineItem objects which are associated with a particular Person object.
readLineItemIdsForCourseOffering	To obtain the set of SourcedIds for the LineItem objects which are associated with a particular CourseOffering object.
readLineItemIdsForCourseSection	To obtain the set of SourcedIds for the LineItem objects which are associated with a particular CourseSection object.
readLineItemIdsForCourseSectionWithLineItemRType	To obtain the set of SourcedIds for the LineItem objects with the required state, which are associated with a particular CourseSection object.
readLineItemIdsFromSavePoint	To obtain the set of SourcedIds for LineItem objects which have been altered since the requested reference point. The reference point is set as ‘zero’ at creation and incremented after every write operation.
readLineItems	To obtain the LineItem objects for a defined set of SourcedIds. This results in a single transaction that may require the exchange of a large volume of data in the response message.
readLineItemsFromSavePoint	To obtain the set of LineItem objects which have been altered since the requested reference point. The reference point is set as ‘zero’ at creation and incremented after every write operation. This results in a single transaction that may require the exchange of a large volume of data in the response message.
updateLineItem	To write new content into the identified LineItem object. The target must write the new data into the LineItem object. This is an additive operation.
replaceLineItem	To replace the content of the identified LineItem object. The target must write the new data into the LineItem object. This is a destructive write-over of all of the original information. In the case of the object not existing, this operation acts as an implied ‘createLineItem’.
discoverLineItemIds	To obtain the set of SourcedIds for LineItem objects whose properties agree with those defined in the query/filter.
changeLineItemIdentifier	To change the SourcedId for a LineItem object.

Note: In most cases the above operations act on a single instance of a Group object i.e., ‘createLineItem’, ‘createByProxyLineItem’, ‘deleteLineItem’, ‘readLineItem’, ‘replaceLineItem’ and ‘updateLineItem’.

3.2.1 CreateLineItem() Operation

Name:	createLineItem
Return Function Parameter:	StatusInfo – the status of the creation request. The permitted status codes are defined in Tables 3.2 and A.2.
Supplied (in) Parameters:	sourcedId:GUID – the sourcedId allocated by the source system. This is the identifier that must also be assigned within the target system. lineItemRecord:LineItemRecord – the LineItem data that is to be stored in the new object.
Returned (out) Parameters:	None.
Behavior:	When the source issues the ‘createLineItem’ request the target is instructed to create the populated LineItem object and to allocate that structure the SourcedId passed by the source. If the supplied SourcedId has already been allocated to another object then the request is rejected and the appropriate failure code is returned. The reference point identifier is set to ‘zero’ for the object in both the source and target.
Notes:	This request contains the initial content for the LineItem object. More content can be added/replaced using the ‘updateLineItem’ and/or ‘replaceLineItem’ requests.

Table 3.2 Status codes for the ‘createLineItem’ operation.

Status Code	Explanation of the Cause of the Code
‘CodeMajor=Success’ ‘Severity=Status’ ‘CodeMinor=fullsuccess’	The creation request has been fully and successfully implemented by the target system and the object has been created with the supplied SourcedId.

‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=unknownvocabulary’	The target system could not identify the defined vocabulary term. This may be due to an incorrect term or a missing vocabulary file.
‘CodeMajor=Success’ ‘Severity=Warning’ ‘CodeMinor=unknownextension’	The target cannot process the proprietary extensions that are used in the object’s data model.

3.2.2 CreateByProxyLineItem() Operation

Name:	createByProxyLineItem
Return Function Parameter:	StatusInfo – the status of the creation request. The permitted status codes are defined in Tables 3.3 and A.2.
Supplied (in) Parameters:	lineItemRecord:LineItemRecord – the LineItem data that is to be stored in the new object.
Returned (out) Parameters:	sourcedId:GUID – the identifier allocated by the target to the newly created LineItem object.

Notes:	This request contains the initial content for the LineItem object. More content can be added/replaced using the ‘updateLineItem’ and/or ‘replaceLineItem’ requests.

Table 3.3 Status codes for the ‘createByProxyLineItem’ operation.

Status Code	Explanation of the Cause of the Code
‘CodeMajor=Success’ ‘Severity=Status’ ‘CodeMinor=fullsuccess’	The creation request has been fully and successfully implemented by the target system and the object has been created with the SourcedId generated by the target.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=idallocfail’	The target could not allocate a unique SourcedId to the object because there are no more spare identifiers available.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=overflowfail’	The target could not create the object due to lack of target allocation memory.

‘CodeMajor=Success’ ‘Severity=Warning’ ‘CodeMinor=unknownextension’	The target cannot process the proprietary extensions that are used in the object’s data model.

3.2.3 DeleteLineItem() Operation

Name:	deleteLineItem
Return Function Parameter:	StatusInfo – the status of the deletion request. The permitted status codes are defined in Tables 3.4 and A.2.
Supplied (in) Parameters:	sourcedId:GUID – the identifier to be used by the target to identify the LineItem object.
Returned (out) Parameters:	None.
Behavior:	When the source issues the ‘deleteLineItem’ request the target is instructed to delete the identified LineItem object and to remove any associations. If the object identified by the supplied SourcedId cannot be located then the request is rejected and the appropriate failure code is returned. The LineItem is deleted and all of the associated Result objects.
Notes:	Deletion of the LineItem object does not necessarily result in the destruction of the data within the server. The true state of the data in the target is unknown.

Table 3.4 Status codes for the ‘deleteLineItem’ operation.

Status Code	Explanation of the Cause of the Code
‘CodeMajor=Success’ ‘Severity=Status’ ‘CodeMinor=fullsuccess’	The deletion request has been fully and successfully implemented by the target system and the objects have been deleted. The corresponding child objects have been deleted.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=unknownobject’	The object identifier is unknown in the target system and so the object could not be deleted.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor= deletefailure’	The target system has not been able to delete the identified object because there are Result objects associated with the LineItem.

3.2.4 ReadLineItem() Operation

Name:	readLineItem
Return Function Parameter:	StatusInfo – the status of the read request. The permitted status codes are defined in Tables 3.5 and A.2.
Supplied (in) Parameters:	sourcedId:GUID – the identifier of the LineItem object to be read.
Returned (out) Parameters:	lineItemRecord:LineItemRecord – the LineItem data that is read from the object.
Behavior:	When the source issues the ‘readLineItem’ request the target is charged with retrieving the identified object from its database and returning this data to the source. The target is responsible for ensuring that the object contains valid data. If the object identified by the supplied SourcedId cannot be located then the request is rejected and the appropriate failure code is returned.
Notes:	The returned LineItem object can only be trusted if the corresponding status code is ‘success’.

Table 3.5 Status codes for the ‘readLineItem’ operation.

Status Code	Explanation of the Cause of the Code
‘CodeMajor=Success’ ‘Severity=Status’ ‘CodeMinor=fullsuccess’	The read request has been fully and successfully implemented by the target system and the identified object has been read from the target system.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=unknownobject’	The object identifier is unknown in the target system and so the object could not be read.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=targetreadfailure’	The target system has detected an error in the stored object and so cannot return the data.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=invaliddata’	Part or all of the returned data was detected as invalid by the source system.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=incompletedata’	Some mandatory part of the data has been detected as missing by the source system.
‘CodeMajor=Success’ ‘Severity=Warning’ ‘CodeMinor=partialdatastorage’	The target has only returned a subset of the data expected by the source e.g., only the mandatory parts.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=unknownvocabulary’	The source system could not identify the defined vocabulary term. This may be due to an incorrect term or a missing vocabulary file.
‘CodeMajor=Success’ ‘Severity=Warning’ ‘CodeMinor=unknownextension’	The source cannot process the proprietary extensions that are used in the object’s data model.

3.2.5 ReadAllLineItemIds() Operation

Name:	readAllLineItemIds
Return Function Parameter:	StatusInfo – the status of the read request. The permitted status codes are defined in Tables 3.6 and A.2.
Supplied (in) Parameters:	None.
Returned (out) Parameters:	sourcedIdSet:GUIDSet – the set of sourcedIds for all of the LineItem objects in the target’s Outcomes database.
Behavior:	When the source issues the ‘readAllLineItemIds’ request the target is charged with returning the SourcedIds of all of the LineItems in its line item database.
Notes:	If no SourcedIds have been allocated then the returned data set is empty and the success status code returned.

Table 3.6 Status codes for the ‘readAllLineItemIds’ operation.

Status Code	Explanation of the Cause of the Code
‘CodeMajor=Success’ ‘Severity=Status’ ‘CodeMinor=fullsuccess’	The read request has been fully and successfully implemented by the target system and the object identifiers have been read from the target system.
‘CodeMajor=Success’ ‘Severity=Status’ ‘CodeMinor= nosourcedids’	The read request has been fully and successfully implemented by the target system and no LineItem object identifiers were found.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=toomuchdata’	The requested data cannot be returned because it would exceed some physical system constraint e.g., permitted size of SOAP message.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=invaliddata’	Part or all of the returned data was detected as invalid by the source system.

3.2.6 ReadLineItemIdsForPerson() Operation

Name:	readLineItemIdsForPerson
Return Function Parameter:	StatusInfo – the status of the read request. The permitted status codes are defined in Tables 3.7 and A.2.
Supplied (in) Parameters:	personSourcedId:GUID – the identifier of the Person object whose LineItem sourcedIds are required.
Returned (out) Parameters:	sourcedIdSet:GUIDSet – the set of SourcedIds for all of the LineItem objects for the Person in the target’s Outcomes database.
Behavior:	The target system must return all of the LineItem SourcedIds for the identified Person object. If the Person object identified by the supplied SourcedId cannot be located then the request is rejected and the appropriate failure code is returned. The association between a Person and the LineItems is defined through a Membership of a Course object e.g., a CourseOffering. The LineItems are then searched for those that have the association with the corresponding Course object.
Notes:	The returned object can only be trusted if the corresponding status code is ‘success’. This Behavior requires that the system support the Membership and Course data models [MMS, 13], [CMS, 13].

Returned (out) Parameters:	lineItemRecordSet:LineItemRecordSet – the set of group records. savePoint:SequenceIdentifier – the value of the reference point counter in the target system.
Behavior:	When the source issues the ‘readLineItemsFromSavePoint’ request the target is charged with reading the objects that have been altered from the defined reference point. If the reference counter in the source is greater than that in the target then an error code is returned and the target value for the reference point is returned.
Notes:	If no objects have been allocated then the return message will be empty. The enclosed data may result in a long response message.

Table 3.14 Status codes for the ‘readLineItemsFromSavePoint’ operation.

Status Code	Explanation of the Cause of the Code
‘CodeMajor=Success’ ‘Severity=Status’ ‘CodeMinor=fullsuccess’	The read request has been fully and successfully implemented by the target system and the identified LineItem object has been read from the target system.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=savepointerror’	An error has occurred in the processing of the save-point identifier information making it impossible to read the correct objects from the database.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=savepointsyncerror’	The value of the save point reference from the source was later than that of the target system. No identifiers have been returned. The target system savepoint value has been updated to that supplied by the source system.

Supplied (in) Parameters:	sourcedId:GUID – the identifier of the LineItem object to be replaced. lineItemRecord:LineItemRecord – the LineItem data that is to be stored in the object.
Returned (out) Parameters:	None.
Behavior:	When the source issues the ‘replaceLineItem’ request the target is charged with writing the supplied information into the identified record. If any part of the write fails e.g., due to partial invalid data then the whole request is rejected and the record is left in its original state. This is a destructive write-over operation of the entire LineItem object. This is equivalent to a ‘createLineItem’ but for an object that already exists. If the object identified by the supplied SourcedId cannot be located then the request is interpreted as a ‘createLineItem’ invocation. The reference counter for the object is incremented by one in the target system.
Notes:	The source is responsible for determining the reason of the failure.

Table 3.15 Status codes for the ‘replaceLineItem’ operation.

Status Code	Explanation of the Cause of the Code
‘CodeMajor=Success’ ‘Severity=Status’ ‘CodeMinor=fullsuccess’	The replace request has been fully and successfully implemented by the target system and the identified object has been changed on the target system.
‘CodeMajor=Success’ ‘Severity=Status’ ‘CodeMinor=createsuccess’	The LineItem object identifier is unknown in the target system and so a new object has been successfully created instead.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=invaliddata’	Part or all of the supplied data was detected as invalid by the target system.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=invalidlineitemtype’	An invalid LineItemType value has been supplied.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=contextunknown’	An unknown context is supplied.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=gradingnotpermitted’	The service consumer is not authorized for grade upload for this CourseSection object.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=incompletedata’	Some mandatory part of the data has been detected as missing by the target system.
‘CodeMajor=Success’ ‘Severity=Warning’ ‘CodeMinor=partialdatastorage’	The target has stored a subset of the sent data record i.e., some of the optional data has not been stored (all mandatory data has been supplied and stored).
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=unknownvocabulary’	The target system could not identify the defined vocabulary term. This may be due to an incorrect term or a missing vocabulary file.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=unknownmdvocabulary’	The target system could not identify the defined metadata vocabulary term. This may be due to an incorrect term or a missing vocabulary file.
‘CodeMajor=Success’ ‘Severity=Warning’ ‘CodeMinor=unknownextension’	The target cannot process the proprietary extensions that are used in the object’s data model.

3.2.15 UpdateLineItem() Operation

Name:	updateLineItem
Return Function Parameter:	StatusInfo – the status of the update request. The permitted status codes are given in Tables 3.16 and A.2.
Supplied (in) Parameters:	sourcedId:GUID – the identifier of the LineItem object to be updated. lineItemRecord:LineItemRecord – the LineItem data that is to be stored in the object.
Returned (out) Parameters:	None.
Behavior:	When the source issues the ‘updateLineItem’ request the target is charged with writing the supplied information into the identified record. If any part of the write fails e.g., due to partial invalid data then the whole request is rejected and the object is left in its original state. This is an additive write operation of all the data fields supplied in the update request and fields not supplied remain unchanged. If a field is constrained with a multiplicity of one then the ‘updateLineItem’ request acts as a replaceLineItem’ request for that field. If the object identified by the supplied SourcedId cannot be located then the request is rejected and the appropriate failure code is returned. The reference counter for the object is incremented by one in the target system.
Notes:	The source is responsible for determining the reason of the failure.

Table 3.16 Status codes for the ‘updateLineItem’ operation.

Status Code	Explanation of the Cause of the Code
‘CodeMajor=Success’ ‘Severity=Status’ ‘CodeMinor=fullsuccess’	The update request has been fully and successfully implemented by the target system and the identified object has been changed on the target system.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=unknownobject’	The object identifier is unknown in the target system and so the object could not be updated.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=invalidlineitemtype’	An invalid LineItemType value has been supplied.

‘CodeMajor=Success’ ‘Severity=Warning’ ‘CodeMinor=partialdatastorage’	The target has stored a subset of the sent data record i.e., some of the optional data has not been stored (all mandatory data has been supplied and stored).
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=unknownvocabulary’	The target system could not identify the defined vocabulary term. This may be due to an incorrect term or a missing vocabulary file.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=unknownmdvocabulary’	The target system could not identify the defined metadata vocabulary term. This may be due to an incorrect term or a missing vocabulary file.
‘CodeMajor=Success’ ‘Severity=Warning’ ‘CodeMinor=unknownextension’	The source cannot process the proprietary extensions that are used in the object’s data model.

3.2.16 DiscoverLineItemIds() Operation

Name:	discoverLineItemIds
Return Function Parameter:	statusInfo:StatusInfo – the status of the update request. The permitted status codes are given in Tables 3.17 and A.2.
Supplied (in) Parameters:	queryObject:QueryObject – this is the query/filter instruction that is to be applied by the target to discover the corresponding LineItem objects.
Returned (out) Parameters:	sourcedIdSet:GUIDSet – the set of identifiers of the LineItem objects whose content conform to the query conditions.
Behavior:	When the source issues the ‘discoverLineItemIds’ the target applies the query instructions to the set of LineItem objects and returns the set of SourcedIds that uphold the query. If no LineItem objects have the required properties the returned data set is empty and the success status code returned. If the target does not understand or cannot apply the requested query then an error status is returned.
Notes:	The internal structure of this QueryObject is undefined (it is should be treated as a String). Later versions of this specification will look at the established best practices for clarification on the use of this operation.

Table 3.17 Status codes for the ‘discoverLineItemIds’ operation.

Status Code	Explanation of the Cause of the Code
‘CodeMajor=Success’ ‘Severity=Status’ ‘CodeMinor=fullsuccess’	The discover request has been fully and successfully implemented by the target system and the identifiers of the objects that uphold the search criteria are returned.

‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=toomuchdata’	The data cannot be returned because it would exceed some physical system constraint e.g., permitted size of SOAP message.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=invaliddata’	Part or all of the returned data was detected as invalid by the source system.

3.2.17 ChangeLineItemIdentifier() Operation

Name:	changeLineItemIdentifier
Return Function Parameter:	StatusInfo – the status of the update request. The permitted status codes are given in Tables 3.18 and A.2.
Supplied (in) Parameters:	sourcedId:GUID – the identifier of the LineItem object to be changed. newSourcedId:GUID – the new identifier to be allocated to the ‘lineItem’ object.
Returned (out) Parameters:	None.
Behavior:	When the source issues the ‘changeLineItemIdentifier’ request the target is charged with replacing the original SourcedId with the new supplied SourcedId. All Membership entries must be similarly changed. All further references to the object must use the new ‘sourcedId’ otherwise an ‘unknown’ object failure status code is returned. If the object identified by the supplied ‘SourcedId’ cannot be located then the request is rejected and the appropriate failure code is returned.
Notes:	The reference pointer value remains unchanged.

Table 3.18 Status codes for the ‘changeLineItemIdentifier’ operation.

Status Code	Explanation of the Cause of the Code
‘CodeMajor=Success’ ‘Severity=Status’ ‘CodeMinor=fullsuccess’	The change identifier request has been fully and successfully implemented by the target system and the LineItem object SourcedId has been changed on the target system.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=idallocinusefail’	The target could not allocate the new unique SourcedId to the LineItem object as the identifier is already in use.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=unknownobject’	The current LineItem SourcedId identifier is unknown in the target system and so the object identifier could not be changed.

3.3 ResultManager Interface Description

Move to top

The ResultManager interface class describes the operations that are permitted on Result objects (as shown Figure 3.2). The set of operations are summarized in Table 3.19.

Figure 3.2 OutcomesManagementService ResultManager interface definitions.

Table 3.19 Summary of operations for ResultManager.

Operation	Description
createResult	To request the creation of a populated Result object on the target system where the source allocates the unique SourcedId. The Result object is tied to a LineItem object.
createByProxyResult	To request the creation of a populated Result object on the target system where the target allocates the unique SourcedId. The Result object is tied to a LineItem object.
deleteResult	To request the deletion of a Result object. The Result object is deleted but the associated ResultValue and LineItems remain.
readResult	To read the full contents of the identified Result object. The target must return all of the data it has for the identified Result object.
readAllResultIds	To obtain the set of SourcedIds assigned to Result objects.
readResultIdsForPerson	To obtain the set of SourcedIds for the Result objects which are associated with a particular Person object.
readResultIdsForLineItem	To obtain the set of SourcedIds for the Result objects which are associated with a particular LineItem object.
readResultIdsForCourseOffering	To obtain the set of SourcedIds for the Result objects which are associated with a particular CourseOffering object.
readResultIdsForCourseSection	To obtain the set of SourcedIds for the Result objects which are associated with a particular CourseSection object.
readResultIdsForCourseSectionWithStatus	To obtain the set of SourcedIds for the Result objects that are associated with a particular CourseSection object and have results of a particular status.
readResultIdsForLineItemWithLineItemType	To obtain the SourcedIds for the Result objects that are associated with a LineItem that has a particular LineItemType state.
readResultIdsFromSavePoint	To obtain the set of identifiers for Result objects which have been altered since the requested reference point. The reference point is set as ‘zero’ at creation and incremented after every write operation.
readResults	To obtain the Result objects for a defined set of identifiers. This results in a single transaction that may require the exchange of a large volume of data.
readResultsFromSavePoint	To obtain the set of Result objects which have been altered since the requested reference point. The reference point is set as ‘zero’ at creation and incremented after every write operation. This results in a single transaction that may require the exchange of a large volume of data in the response message.
updateResult	To add content to the identified Result object. The target must write the new data into the Result object. This is an additive operation.
replaceResult	To replace the content of the identified Result object. The target must write the new data into the Result object. This is a destructive write-over of all of the original information. In the case of the object not existing, this operation acts as an implied ‘createResult’.
replaceResultsForLineItem	To replace the Result records for all of the PersonSourcedIds for a specific LIneItem object. In the case of the object not existing, this operation acts as an implied ‘createResult’.
discoverResultIds	To obtain the set of SourcedIds for Result objects whose properties agree with those defined in the query/filter.
changeResultIdentifier	To change the SourcedId of a Result object.

Note: In most cases the above operations act on a single instance of a Group object i.e., ‘createResult’, ‘createByProxyResult’, ‘deleteResult’, ‘readResult’, ‘replaceResult’ and ‘updateResult’.

This is the identifier that must also be assigned within the target system. lineItemSourcedId:GUID – the sourcedId of the LineItem object to which the Result object is assigned. resultRecord:ResultRecord – the Result data that is to be stored in the new object.
Returned (out) Parameters:	None.
Behavior:	When the source issues the ‘createResult’ request the target is instructed to create the populated Result object and to allocate that structure the SourcedId passed by the source. If the supplied SourcedId has already been allocated to another object then the request is rejected and the appropriate failure code is returned. The reference point identifier is set to ‘zero’ for the Result object in both the source and target. The Result object is assigned to the identified LineItem object. If an invalid sourcedId is given for the LineItem object then an error code is returned and the Result object is not created.
Notes:	This request contains the initial content for the Result object. More content can be added/replaced using the ‘updateResult’ and/or ‘replaceResult’ requests.

‘CodeMajor=Success’ ‘Severity=Status’ ‘CodeMinor=partialreadfail’	Some of the Result object identifiers are unknown in the target system and so those objects could not be read.
‘CodeMajor=Success’ ‘Severity=Warning’ ‘CodeMinor=partialdatareturn’	The target has only returned a subset of the data object e.g., only the mandatory parts.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=toomuchdata’	The data cannot be returned because it would exceed some physical system constraint e.g., permitted size of SOAP message.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=savepointerror’	An error has occurred in the processing of the save-point identifier information making it impossible to read the correct objects from the database.

Behavior:	When the source issues the ‘replaceResult’ request the target is charged with writing the supplied information into the identified record. If any part of the write fails e.g., due to partial invalid data then the whole request is rejected and the record is left in its original state. This is a destructive write-over operation of the entire Result object. This is equivalent to a ‘createResult’ but for an object that already exists. If the object identified by the supplied SourcedId cannot be located then the request is interpreted as a ‘createResult’ invocation. The reference counter for the object is incremented by one in the target system.
Notes:	The source is responsible for determining the reason of the failure.

‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=invaliddata’	Part or all of the supplied data was detected as invalid by the target system.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=incompletedata’	Some mandatory part of the data has been detected as missing by the target system.
‘CodeMajor=Success’ ‘Severity=Warning’ ‘CodeMinor=partialdatastorage’	The target has stored a subset of the sent data record i.e., some of the optional data has not been stored (all mandatory data has been supplied and stored).
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=unknownvocabulary’	The target system could not identify the defined vocabulary term. This may be due to an incorrect term or a missing vocabulary file.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=unknownmdvocabulary’	The target system could not identify the defined metadata vocabulary term. This may be due to an incorrect term or a missing vocabulary file.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=unknownextension’	The target cannot process the proprietary data model extensions used in the object.

3.3.16 ReplaceResultsForLineItem() Operation

Name:	replaceResultsForLineItem
Return Function Parameter:	statusInfo:StatusInfo – the status of the replace request. The permitted status codes are given in Tables 3.35 and A.2.
Supplied (in) Parameters:	resultRecordSet:ResltRecordSet – the set of result records that are to replace the current Result objects; lineItemSourcedId:GUID – the identifier of the LineItem object for which the results are to be replaced.
Returned (out) Parameters:	replaceStatusCodes:ReplaceStatusCodes – the list of status codes returned for the each of the replacement requests in the transaction.
Behavior:	When the source issues the ‘replaceResultsForLineItem’ request the target is charged with writing the supplied information into the identified result records for the identified LineItem object. Each Result object replace is treated as an independent request and the corresponding status code is returned in the response message body (see Table B1.3 for the permitted values). This is a destructive write-over operation of the entire Result object. This is equivalent to a ‘createResult’ but for an object that already exists. If an identified Result object cannot be located then the request is interpreted as a ‘createResult’ invocation. Intended usage of replaceResultsForLineItem is to create or replace multiple Results with the exact same LineItemSourcedId. The lineItemSourcedId which is passed in as a parameter will be used initially to validate the existance of the given lineItem; then subsequently any Result record which contains a lineItemSourcedId which is not the same as the top level one will be flagged as an exception. This also means that should there be a need to submit a request for creating or replace multiple results with DIFFERENT lineitemSourcedIds, then it should be done using separate replaceResutlsforLineItem calls. The reference counter for each object is incremented by one in the target system. An overall status code is returned for the request as a whole.
Notes:	The source is responsible for determining the reason of the failure.

Table 3.35 Status codes for the ‘replaceResultsForLineItem’ operation.

Status Code	Explanation of the Cause of the Code
‘CodeMajor=Success’ ‘Severity=Status’ ‘CodeMinor=fullsuccess’	The replace request has been fully and successfully implemented by the target system and the identified objects have been changed on the target system.
‘CodeMajor=Success’ ‘Severity=Status’ ‘CodeMinor=unknownobject’	The identified LineItem object is unknown i.e., the supplied sourcedId is not assigned to a Lineitem object.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=invaliddata’	Some of the request has failed due to one or more data validation failures. See the specific request codes (given in the replaceStatusCode parameter) for further information for the cause(s) of the failure.

3.3.17 UpdateResult() Operation

Name:	updateResult
Return Function Parameter:	StatusInfo – the status of the update request. The permitted status codes are given in Tables 3.36 and A.2.
Supplied (in) Parameters:	sourcedId:GUID – the identifier of the Result object to be updated. resultRecord:ResultRecord – the Result data that is to be stored in the object.
Returned (out) Parameters:	None.
Behavior:	When the source issues the ‘updateResult’ request the target is charged with writing the supplied information into the identified record. If any part of the write fails e.g., due to partial invalid data then the whole request is rejected and the record is left in its original state. This is an additive write operation of all the data fields supplied in the update request and fields not supplied remain unchanged. If a field is constrained with a multiplicity of one then the ‘updateResult’ request acts as a replaceResult’ request for that field. If the object identified by the supplied SourcedId cannot be located then the request is rejected and the appropriate failure code is returned. The reference counter for the object is incremented by one in the target system.
Notes:	The source is responsible for determining the reason of the failure.

Table 3.36 Status codes for the ‘updateResult’ operation.

Status Code	Explanation of the Cause of the Code
‘CodeMajor=Success’ ‘Severity=Status’ ‘CodeMinor=fullsuccess’	The update request has been fully and successfully implemented by the target system and the identified object has been changed on the target system.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=unknownobject’	The object identifier is unknown in the target system and so the object could not be updated.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=invaliddata’	Part or all of the returned data was detected as invalid by the target system.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=incompletedata’	Some mandatory part of the data has been detected as missing by the target system.
‘CodeMajor=Success’ ‘Severity=Warning’ ‘CodeMinor=partialdatastorage’	The target has stored a subset of the sent data record i.e., some of the optional data has not been stored (all mandatory data has been supplied and stored).
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=unknownvocabulary’	The target system could not identify the defined vocabulary term. This may be due to an incorrect term or a missing vocabulary file.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=unknownmdvocabulary’	The target system could not identify the defined metadata vocabulary term. This may be due to an incorrect term or a missing vocabulary file.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=unknownextension’	The target cannot process the proprietary data model extensions used in the object.

3.3.18 DiscoverResultIds() Operation

Name:	discoverResultIds
Return Function Parameter:	statusInfo:StatusInfo – the status of the discover request. The permitted status codes are given in Tables 3.37 and A.2.
Supplied (in) Parameters:	queryObject:QueryObject – this is the query/filter instruction that is to be applied by the target to discover the corresponding Result objects.
Returned (out) Parameters:	sourcedIdSet:GUIDSet – the set of identifiers of the Result objects whose content conform to the query conditions.
Behavior:	When the source issues the ‘discoverResultIds’ the target applies the query instructions to the set of Result objects and returns the set of SourcedIds that uphold the query/filter. If no Result objects have the required properties the returned data set is empty and the success status code returned. If the target does not understand or cannot apply the requested query/filter then an error status is returned.
Notes:	The internal structure of this QueryObject is undefined (it is should be treated as a String). Later versions of this specification will look at the established best practices for clarification on the use of this operation.

Table 3.37 Status codes for the ‘discoverResultIds’ operation.

Status Code	Explanation of the Cause of the Code
‘CodeMajor=Success’ ‘Severity=Status’ ‘CodeMinor=fullsuccess’	The discover request has been fully and successfully implemented by the target system and the object identifiers for the Results that uphold the search criteria.
‘CodeMajor=Success’ ‘Severity=Status’ ‘CodeMinor= nosourcedids’	The discover request has been fully and successfully implemented by the target system and no LineItem object identifiers were found.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=unknownquery’	The query/filter instruction is unknown in the target system and so the query/filter could not be executed.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=toomuchdata’	The data cannot be returned because it would exceed some physical system constraint e.g., permitted size of SOAP message.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=invaliddata’	Part or all of the returned data was detected as invalid by the source system.

3.3.19 ChangeResultIdentifier() Operation

Supplied (in) Parameters:	sourcedId:GUID – the identifier of the Result object to be changed. newSourcedId:GUID – the new identifier to be allocated to the Result object.
Returned (out) Parameters:	None.
Behavior:	When the source issues the ‘changeResultIdentifier’ request the target is charged with replacing the original SourcedId with the new supplied SourcedId. All further references to the object must use the new SourcedId otherwise an ‘unknown’ object failure status code is returned. If the object identified by the supplied SourcedId cannot be located then the request is rejected and the appropriate failure code is returned.
Notes:	The reference pointer value remains unchanged.

Table 3.38 Status codes for the ‘changeResultIdentifier’ operation.

Status Code	Explanation of the Cause of the Code
‘CodeMajor=Success’ ‘Severity=Status’ ‘CodeMinor=fullsuccess’	The change identifier request has been fully and successfully implemented by the target system and the Result object SourcedId has been changed on the target system.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=idallocinusefail’	The target could not allocate the new unique ‘identifier’ to the Result object as the identifier is already in use.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=unknownobject’	The current Result SourcedId identifier is unknown in the target system and so the object identifier could not be changed.

3.4 ResultValueManager Interface Description

Move to top

The ResultValueManager interface class describes the operations that are permitted on ResultValue objects (as shown Figure 3.3). The set of operations are summarized in Table 3.39.

Figure 3.3 OutcomesManagementService ResultValueManager interface definitions.

Table 3.39 Summary of operations for ResultValueManager.

Operation	Description
createResultValue	To request the creation of a populated ResultValue object on the target system where the source is responsible for the allocation of the unique SourcedId.
createByProxyResultValue	To request the creation of a populated ResultValue object on the target system where the target is responsible for the allocation of the unique SourcedId.
deleteResultValue	To request the deletion of a ResultValue object. The ResultValue object is deleted along with all of its associated relationships.
readResultValue	To read the full contents of the identified ResultValue object. The target must return all of the data it has for the identified ResultValue object.
readAllResultValueIds	To obtain the set of SourcedIds which have been assigned to ResultValue objects.
readResultValueIdForLineItem	To obtain the SourcedId for the ResultValue object which has been associated with a particular LineItem object.
readResultValueIdForResult	To obtain the SourcedId for the ResultValue object which is associated with a particular Result object.
readResultValueIdsFromSavePoint	To obtain the set of identifiers for ResultValue objects which have been altered since the requested reference point. The reference point is set as ‘zero’ at creation and incremented after every write operation.
readResultValues	To obtain the ResultValue objects for a defined set of identifiers. This results in a single transaction that may require the exchange of a large volume of data in the response message.
readResultValuesFromSavePoint	To obtain the set of ResultValue objects which have been altered since the requested reference point. The reference point is set as ‘zero’ at creation and incremented after every write operation. This results in a single transaction that may require the exchange of a large volume of data in the response message.
updateResultValue	To write new content into the identified ResultValue object. The target must write the new data into the ResultValue object. This is an additive operation.
replaceResultValue	To replace the content of the identified ResultValue object. The target must write the new data into the ResultValue object. This is a destructive write-over of all of the original information. In the case of the object not existing, this operation acts as an implied ‘createResultValue’.
discoverResultValueIds	To obtain the set of SourcedIds for ResultValue objects whose properties agree with those defined in the query/filter.
changeResultValueIdentifier	To change the SourcedId for a ResultValue object.

Note: In most cases the above operations act on a single instance of a Group object i.e., ‘createResultValue’, ‘createByProxyResultValue’, ‘deleteResultValue’, ‘readResultValue’, ‘replaceResultValue’ and ‘updateResultValue’.

‘CodeMajor=Success’ ‘Severity=Status’ ‘CodeMinor=fullsuccess’	The read request has been fully and successfully implemented by the target system and the identified ResultValue object has been read from the target system.
‘CodeMajor=Success’ ‘Severity=Status’ ‘CodeMinor=partialreadfail’	Some of the ResultValue object identifiers are unknown in the target system and so those objects could not be read.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=savepointerror’	An error has occurred in the processing of the save-point identifier information making it impossible to read the correct objects from the database.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=savepointsyncerror’	The value of the save point reference from the source was later than that of the target system. No identifiers have been returned. The target system savepoint value has been updated to that supplied by the source system.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=toomuchdata’	The data cannot be returned because it would exceed some physical system constraint e.g., permitted size of SOAP message.
‘CodeMajor=Success’ ‘Severity=Warning’ ‘CodeMinor=partialdatareturn’	The target has only returned a subset of the data object e.g., only the mandatory parts.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=targetreadfailure’	The target system has detected an error in the stored Result object and so cannot return the data.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=invaliddata’	Part or all of the returned data was detected as invalid by the target system.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=incompletedata’	Some mandatory part of the data has been detected as missing by the target system.

3.4.11 ReplaceResultValue() Operation

Name:	replaceResultValue
Return Function Parameter:	statusInfo:StatusInfo – the status of the replace request. The permitted status codes are given in Tables 3.50 and A.2.
Supplied (in) Parameters:	sourcedId:GUID – the identifier of the ResultValue object to be replaced. resultValueRecord:ResultValueRecord – the ResultValue data that is to be stored in the object.
Returned (out) Parameters:	None.
Behavior:	When the source issues the ‘replaceResultValue’ request the target is charged with writing the supplied information into the identified record. If any part of the write fails e.g., due to partial invalid data then the whole request is rejected and the record is left in its original state. This is a destructive write-over operation of the entire ‘result’ object. This is equivalent to a ‘createResultValue’ but for an object that already exists. If the object identified by the supplied SourcedId cannot be located then the request is interpreted as a ‘createResultValue’ invocation. The reference counter for the object is incremented by one in the target system.
Notes:	The source is responsible for determining the reason of the failure.

Table 3.50 Status codes for the ‘replaceResultValue’ operation.

Status Code	Explanation of the Cause of the Code
‘CodeMajor=Success’ ‘Severity=Status’ ‘CodeMinor=fullsuccess’	The replace request has been fully and successfully implemented by the target system and the identified object has been changed on the target system.
‘CodeMajor=Success’ ‘Severity=Status’ ‘CodeMinor=createsuccess’	The ResultValue object identifier is unknown in the target system and so a new object has been successfully created instead.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=invaliddata’	Part or all of the returned data was detected as invalid by the target system.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=incompletedata’	Some mandatory part of the data has been detected as missing by the target system.
‘CodeMajor=Success’ ‘Severity=Warning’ ‘CodeMinor=partialdatastorage’	The target has stored a subset of the sent data record i.e., some of the optional data has not been stored (all mandatory data has been supplied and stored).
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=unknownvocabulary’	The target system could not identify the defined vocabulary term. This may be due to an incorrect term or a missing vocabulary file.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=unknownmdvocabulary’	The target system could not identify the defined metadata vocabulary term. This may be due to an incorrect term or a missing vocabulary file.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=unknownextension’	The source cannot process the proprietary data model extensions used in the object.

3.4.12 UpdateResultValue() Operation

Name:	updateResultValue
Return Function Parameter:	StatusInfo – the status of the update request. The permitted status codes are given in Tables 3.51 and A.2.
Supplied (in) Parameters:	sourcedId:GUID – the identifier of the ResultValue object to be updated. resultValueRecord:ResultValueRecord – the ResultValue data that is to be stored in the object.
Returned (out) Parameters:	None.
Behavior:	When the source issues the ‘updateResultValue’ request the target is charged with writing the supplied information into the identified object. If any part of the write fails e.g., due to partial invalid data then the whole request is rejected and the record is left in its original state. This is an additive write operation of all the data fields supplied in the update request and fields not supplied remain unchanged. If a field is constrained with a multiplicity of one then the ‘updateResultValue’ request acts as a replaceResultValue’ request for that field. If the object identified by the supplied SourcedId cannot be located then the request is rejected and the appropriate failure code is returned. The reference counter for the object is incremented by one in the target system.
Notes:	The source is responsible for determining the reason of the failure.

Table 3.51 Status codes for the ‘updateResultValue’ operation.

Status Code	Explanation of the Cause of the Code
‘CodeMajor=Success’ ‘Severity=Status’ ‘CodeMinor=fullsuccess’	The update request has been fully and successfully implemented by the target system and the identified object has been changed on the target system.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=unknownobject’	The object identifier is unknown in the target system and so the object could not be updated.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=invaliddata’	Part or all of the returned data was detected as invalid by the target system.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=incompletedata’	Some mandatory part of the data has been detected as missing by the target system.
‘CodeMajor=Success’ ‘Severity=Warning’ ‘CodeMinor=partialdatastorage’	The target has stored a subset of the sent data record i.e., some of the optional data has not been stored (all mandatory data has been supplied and stored).
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=unknownvocabulary’	The target system could not identify the defined vocabulary term. This may be due to an incorrect term or a missing vocabulary file.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=unknownmdvocabulary’	The target system could not identify the defined metadata vocabulary term. This may be due to an incorrect term or a missing vocabulary file.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=unknownextension’	The source cannot process the proprietary data model extensions used in the object.

3.4.13 DiscoverResultValueIds() Operation

Name:	discoverResultValueIds
Return Function Parameter:	statusInfo:StatusInfo – the status of the discover request. The permitted status codes are given in Tables 3.52 and A.2.
Supplied (in) Parameters:	queryObject:QueryObject – this is the query/filter instruction that is to be applied by the target to discover the corresponding ResultValue objects.
Returned (out) Parameters:	sourcedIdSet:GUIDSet – the set of identifiers of the ResultValue objects whose content conform to the query conditions.
Behavior:	When the source issues the ‘discoverResultValueIds’ the target applies the query/filter instructions to the set of ResultValue objects and returns the set of SourcedIds that uphold the query/filter. If no ResultValue objects have the required properties the returned data set is empty and the success status code returned. If the target does not understand or cannot apply the requested query/filter then an error status is returned.
Notes:	The internal structure of this QueryObject is undefined (it is should be treated as a String). Later versions of this specification will look at the established best practices for clarification on the use of this operation.

Table 3.52 Status codes for the ‘discoverResultValueIds’ operation.

Status Code	Explanation of the Cause of the Code
‘CodeMajor=Success’ ‘Severity=Status’ ‘CodeMinor=fullsuccess’	The discover request has been fully and successfully implemented by the target system and the identifiers of the objects that uphold the search criteria have been returned.
‘CodeMajor=Success’ ‘Severity=Status’ ‘CodeMinor= nosourcedids’	The read request has been fully and successfully implemented by the target system and no ResultValue object identifiers were found.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=unknownquery’	The query/filter instruction is unknown in the target system and so the query could not be executed.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=toomuchdata’	The data cannot be returned because it would exceed some physical system constraint e.g., permitted size of SOAP message.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=invaliddata’	Part or all of the returned data was detected as invalid by the source system.

3.4.14 ChangeResultValueIdentifier() Operation

Name:	changeResultValueIdentifier
Return Function Parameter:	StatusInfo – the status of the update request. The permitted status codes are given in Tables 3.53 and A.2.
Supplied (in) Parameters:	sourcedId:GUID – the identifier of the ResultValue object to be changed. newSourcedId:GUID – the new identifier to be allocated to the ResultValue object.
Returned (out) Parameters:	None.
Behavior:	When the source issues the ‘changeResultValueIdentifier’ request the target is charged with replacing the original SourcedId with the new supplied SourcedId. If the object identified by the supplied SourcedId cannot be located then the request is rejected and the appropriate failure code is returned.
Notes:	The reference pointer value remains unchanged.

Table 3.53 Status codes for the ‘changeResultValueIdentifier’ operation.

Status Code	Explanation of the Cause of the Code
‘CodeMajor=Success’ ‘Severity=Status’ ‘CodeMinor=fullsuccess’	The change identifier request has been fully and successfully implemented by the target system and the ResultValue object SourcedId has been changed on the target system.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=idallocinusefail’	The target could not allocate the new unique ‘identifier’ to the ResultValue object as the identifier is already in use.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=unknownobject’	The current ResultValue SourcedId identifier is unknown in the target system and so the object identifier could not be changed.

3.5 State Machines

Move to top

The permitted state activity on a LineItem, Result and ResultValue object are shown in Figures 3.4, 3.5 and 3.6 respectively. Each state diagram has three states (the arcs are annotated with the operations that are associated with the change of state):

· ‘No Object’ state – no object exists with a particular sourcedId;

· ‘Object with Provider assigned sourcedId’ – an object exists with the sourcedId allocated by the Provider system;

· ‘Object with Consumer assigned sourcedId’ – an object exists with the sourcedId allocated by the Consumer system.

The state machine for a LineItem object is shown in Figure 3.4.

Figure 3.4 State machine for a ‘lineItem’ object.

The start state is ‘No Object’ i.e., the LineItem object has not yet been created. Only the ‘createLineItem()’, ‘replaceeLineItem()’ and ‘createByProxyLineItem()’ operations are possible. Once the LineItem object has been created then it persists until a successful ‘deleteLineItem()’ operation is completed. The ‘createLineItem()’ and replaceLineItem()’ operations take the system into the ‘Object with Consumer assigned sourcedId’ state whereas the ‘createByProxyLineItem()’ takes the system into the ‘Object with Provider assigned sourcedId’ state.

The system can be moved from the ‘Object with Provider assigned sourcedId’ state into the ‘Object with Consumer assigned sourcedId’ state by the successful completion of the ‘changeLineItemIdentifier()’ operation.

Once the system is in the ‘Object with Consumer assigned sourcedId’ or the ‘Object with Provider assigned sourcedId’ states then the ‘readLineItem()’, ‘readAllLineItemIds()’, ‘readLineItemIdsForPerson()’, ‘readLineItemIdsForCourseOffering()’, ‘readLineItemIdsForCourseSection()’, ‘readLineItemIdsForCourseSectionWithLineItemType()’, ‘readLineItemIdsWithLineItemType()’, ‘readLineItemIdsFromSavePoint()’, ‘readLineItems()’, ‘readLineItemsFromSavePoint()’, ‘updateLineItem()’, ‘replaceLineItem()’ and ‘discoverLineItemIds()’ operations are now possible.

This is the state machine for each LineItem object in the Service Consumer and the Service Provider. The binding of the Information Model must guarantee that these two state machines remain synchronized for each LineItem object.

The state machine for a Result object is shown in Figure 3.5.

Figure 3.5 State machine for a ‘result’ object.

The start state is ‘No Object’ i.e., the Result object has not yet been created. Only the ‘createResult()’, ‘replaceResult()’ and ‘createByProxyResult()’ operations are possible. Once the Result object has been created then it persists until a successful ‘deleteResult()’ operation is completed. The ‘createResult()’ and ‘replaceResult()’ operations take the system into the ‘Object with Consumer assigned sourcedId’ state whereas the ‘createByProxyResult()’ takes the system into the ‘Object with Provider assigned sourcedId’ state.

Once the system is in the ‘Object with Consumer assigned sourcedId’ or the ‘Object with Provider assigned sourcedId’ states then the ‘readResult()’, ‘readAllResultIds()’, ‘readResultIdsForPerson()’, ‘readResultIdsForLineItem()’, ‘readResultIdsForCourseOffering()’, ‘readResultIdsForCourseSection()’, ‘readResultIdsForCourseSectonWithStatus()’, ‘readResultIdsForLineItemWithLineItemType()’, ‘readResultIdsFromSavePoint()’, ‘readResults()’, ‘readResultsFromSavePoint()’, ‘updateResult()’, ‘replaceResult()’, ‘replaceResultsForLineItem()’ and ‘discoverResultIds()’ operations are now possible.

This is the state machine for each Result object in the Service Consumer and the Service Provider. The binding of the Information Model must guarantee that these two state machines remain synchronized for each result object.

The state machine for a ResultValue object is shown in Figure 3.6.

Figure 3.6 State machine for a ‘resultValue’ object.

The start state is ‘No Object’ i.e., the ResultValue object has not yet been created. Only the ‘createResultValue()’, ‘replaceResultValue()’ and ‘createByProxyResultValue()’ operations are possible. Once the ResultValue object has been created then it persists until a successful ‘deleteResultValue()’ operation is completed. The ‘createResultValue()’ and replaceResultValue()’ operations take the system into the ‘Object with Consumer assigned sourcedId’ state whereas the ‘createByProxyResultValue()’ takes the system into the ‘Object with Provider assigned sourcedId’ state.

Once the system is in the ‘Object with Consumer assigned sourcedId’ or the ‘Object with Provider assigned sourcedId’ states then the ‘readResultValue()’, ‘readAllResultValueIds()’, ‘readResultValueIdForLineItem()’, ‘readResultIdForResult()’, ‘readResultValueIdsFromSavePoint()’, ‘readResultValues()’, ‘readResultValuesFromSavePoint()’, ‘updateResultValue()’, ‘replaceResultValue()’ and ‘discoverResultValueIds()’ operations are now possible.

This is the state machine for each ResultValue object in the Service Consumer and the Service Provider. The binding of the Information Model must guarantee that these two state machines remain synchronized for each ResultValue object.

4 Interface Data Model

The set of operations described within the behavior model (Section 3) are based upon class descriptions specific to the parameters of the operations. It is these classes that are now described.

4.1 GUID Class Description

Move to top

This is the data type for the globally unique sourcedIds. These GUIDs must be unique across the set of communicating end-systems within the Learning Information Services system. The internal format of the GUID is outside the scope of this specification but they must all be valid strings. Any implementation of the GUID class must be able to support GUIDs of at least 1024 octets in length i.e., the shortest permitted maximum length.

4.2 GUIDSet Class Description

Move to top

This is the data-type for a set of GUIDs (zero or more). Any implementation of the GUIDSet must be able to contain at least 250,000 GUIDs i.e., the smallest permitted maximum number.

4.3 LineItemRecord Class Description

Move to top

This is the data-type for Line Items. The data model for a Line Item is described in Section 5. A key difference for an object passed in the interface, as opposed to the requirement for an end-system, is that the content is dependent on the type of operation. A LineItemRecord object must consist of the SourcedId of the LineItem object and the LineItem object itself.

4.4 LineItem RecordSet Class Description

Move to top

This is the data-type for a set of LineItemRecords (zero or more). Any implementation of the LineItemRecordSet must be able to contain at least 100,000 LineItemRecords i.e., the smallest permitted maximum number.

4.5 LineItemType Class Description

Move to top

This is the data-type for the enumerated list of states used to define the status of a LineItem. The list of permitted values is: { MidTerm, Interim, Final } (this must be implemented as an extensible vocabulary).

4.6 QueryObject Class Description

Move to top

This is the data-type for the query instruction. This is a String with the smallest permitted maximum length of 4096 octets. The internal structure of this string is undefined. Later versions of this specification will look at the established best practices for clarification on the use of this string.

4.7 ResultRecord Class Description

Move to top

This is the data-type for Results. The data model for a Result is described in Section 5. A key difference for an object passed in the interface, as opposed to the requirement for an end-system, is that the content is dependent on the type of operation. A ResultRecord object must consist of the SourcedId of the Result object and the Result object itself.

4.8 ResultRecordSet Class Description

Move to top

This is the data-type for a set of ResultRecords (zero or more). Any implementation of the ResultRecordSet must be able to contain at least 250,000 ResultRecords i.e., the smallest permitted maximum number.

4.9 ResultStatus Class Description

Move to top

This is the data-type for the enumerated list of states used to define the status of a Result. The list of permitted values is: { Unmoderated, Tobemoderated, Pending, Completed } (this must be implemented as an extensible vocabulary).

4.10 ResultValueRecord Class Description

Move to top

This is the data-type for Result Values. The data model for a Result Value is described in Section 5. A key difference for an object passed in the interface, as opposed to the requirement for an end-system, is that the content is dependent on the type of operation. A ResultValueRecord object must consist of the SourcedId of the ResultValue object and the ResultValue object itself.

4.11 ResultValueRecordSet Class Description

Move to top

This is the data-type for a set of ResultValueRecords (zero or more). Any implementation of the ResultValueRecordSet must be able to contain at least 1000 ResultValueRecords i.e., the smallest permitted maximum number.

4.12 SequenceIdentifier Class Description

Move to top

This is the data-type for the sequence identifier used to denote identify the synchronization reference point between the two communicating systems. The sequence is denoted by the date-time string YYYY-MM-DDTHH:MM:SS.NNN where ‘YYYY’ denotes the year, the first ‘MM’ string the month (01-12), ‘DD’ the day (01-31), ‘HH’ the hour (00-23), the second ‘MM’ string the minute (00-59), ‘SS’ the second (00-59) and ‘NN’ the millisecond value (000-999).

At initialization the value is set to ‘2000-01-01T00:00:00.000’. The value is changed to the current time for every operation that results in a change of the value of the data stored in the associated object.

All values are to be rounded down at the level of greatest resolution.

4.13 StatusInfo Class Description

Move to top

This is the data-type for the status information returned by the target to the source. The structure of this class is described in the 1EdTech GLC General Web Services specification v1.0 (Appendix A) [GWS, 05].

4.14 ReplaceStatusCodes Class Description

The syntax and semantics of the approved list of terms shall be supported by all software components implementing this Information Model. The value space for the vocabulary may be extended. Such extending expressions may be created and used only when no approved 1EdTech value satisfies the expressive need of an implementing community to define the shape of a collection.
Multiplicity	1
Description	The reported status of the result replacement request for the Result object identified by the associated ‘sourcedId’.

5 End System Data Model

The end system data model defines the persistence model that must be maintained by an end system to ensure the correct system behavior.

An informative overview of the entire Persistence Data Model is provided as a Platform Independent Model (PIM) expressed in UML constructs. All UML diagrams expressed as “Platform Independent Model” are non-normative. Normative tables defining the classes in this Information Model follow the informative UML diagrams. A full definition of the UML Profile and the terms used in the normative tabular descriptions in this document to describe the PIM can be found in [SDN07, 06].

In the tables in this section the character sequence “n/a” is used to mark a field “not applicable.” Any field so marked is not relevant to the class being defined. Features so marked shall be ignored when binding a class defined by this Information Model.

5.1 Key terms and concepts

Move to top

Classes in this information model are classified into four abstract class types. These abstractions are bound to specific data structures for machine processing in the 1EdTech Outcomes Management Services WSDL Binding [OMS, 13]. The abstract class types are:

· container: A container class may be a parent of one or more child classes;

· value: A value class shall not be a parent. That is, it shall not be a composite of characteristic, container, value, or unspecified class types. A value class shall always be a child of a container class and shall have semantic value within the scope of its parent class’s semantic value;

· unspecified: An unspecified class may be a parent. An unspecified class serves as an extension point for this Information Model.

Table 5.1 lists the class descriptors used to describe the abstract classes and definitions of the descriptors.

Table 5.1 Class descriptors

Descriptor	Definition
Class name	The name given to the class being described.
Class type	The abstract class type of this class.
Data type	For value and characteristic classes, the allowed structure for valid values for the class. Valid data types are: DateTime: The DateTime represents a combined date and time in the format of ISO 8601 i.e., ‘YYYY-MM-DDTHH:MM:SS±TZ’. The time is denoted in Coordinated Universal Time. Decimal: A real number. GUID: An identifier that is globally unique within the Learning Information Services System. This will be based upon the Normalized String data-type that has a constrained value-space. Integer: An integer. NormalizedString: A sequence of printable characters that does not contain carriage returns or tabs. String: A sequence of printable characters. Text: A language annotated string (this is in fact a separate class but it is treated as data-type for convenience). The string is accompanied by an attribute that denotes the language for the string. AnyURI: Any syntactically valid instance of a URI as defined in RFC3986. Note: Many of the foundational Specifications, Standards, and Recommendations referred to by this Information Model use RFC2396 and RFC2732 as the definitions of URI. These are made obsolete by RFC3986, but many of the foundational documents have not been updated to reference RFC3986. URL: A normalized string that is used to contain a Universal Resource Location. unspecified: The data type is not known or is not important.
Value space	The range of valid values for this class. If the value space is unspecified, it is not known or is not important.
Multiplicity	A property of a class indicating the number of times it may be used or appear in a given parent context. The values of this property are expressed as a range or shorthand for a range using this notation: ‘0..1’ [optional; restricted] ‘0..unbounded’ [optional; unrestricted] ‘1..1’ [mandatory; restricted] ‘1..unbounded’ [mandatory; unrestricted] Multiplicities may also appear in short-hand notation in the UML models. The short-hand equivalents shall be (exclusive of bracketed comments): ‘’ [optional; unrestricted] ‘1’ [mandatory; restricted] ‘1..’ [mandatory; unrestricted] Where multiplicity is greater than one, the importance of the ordering of siblings is also indicated by appending either “,”ordered or “,” unordered. ordered specifies a sequence of siblings as listed, unordered specifies a collection or bag of siblings for which the order is not important.
Parents	Lists classes that may be parents of this class.
Children	Lists the possible child classes of this class in the form “[” child “,” child “]”. One or more child classes may be expressed within square brackets. Each child class in the list shall be separated by a comma. Where more than one child is listed, the importance of the ordering of siblings is also indicated by appending either “,”ordered* or “,” unordered. ordered specifies a sequence of siblings as listed, unordered specifies a collection or bag of siblings for which the order is not important
Description	Contains descriptions relating to the class and its values space.

In general, this specification does not define the ways in which an end system must be realized. However, the required interoperability behavior requires that an end system have certain characteristics. The static properties of these characteristics are defined in this Section, including:

· When an attribute has a multiplicity of ‘1..1’ then an end system must be capable of supporting one instance;

· When an attribute has a multiplicity of ‘1..*’ then an end system must be capable of supporting at least one instance. The specification will also define the smallest permitted maximum number of instances that must also be supported by the end system;

· When an attribute has a multiplicity of ‘0..1’ then an end system should support a single instance;

· When an attribute has a multiplicity of ‘0..*’ then the specification will define the smallest permitted maximum number of instances that must also be supported by the end system.

When the object is passed as part of a service call then attributes that have a ‘1..1’ or ‘1..*’ multiplicity may not be exchanged. This is because the specification of an end system defines capability; an operational system may or may not exchange the associated information.

5.2 The Structure of an Outcome

Move to top

The conceptual data model for the structure of an outcome is shown in Figure 5.1. There are three facets of the Outcome structure:

· The components of the core data model of the course denoted in Figure 5.1 by the LineItem, Result and ResultValue classes;

· The reference structures that are used to identify specific instances of each part of the Outcomes are denoted in Figure 5.1 by the classes LineItemRecord, ResultRecord and ResultValueRecord.

6 Extending and Profiling the Service

6.1 Proprietary Extensions

Move to top

Proprietary extensions of the service are based upon two approaches:

a) The extension of the data models being manipulated by the current set of operations;

b) The inclusion of new operations to support new proprietary functionality.

It is NOT permitted to change the Behavior of the current set of operations. Such changes MUST be supported by the creation of new operations.

6.1.1 Proprietary Operations

The definition of new operations should follow the same format as adopted herein. The new operations should be defined using a new interface type. Every operation must result in the return of a status code that describes the final state of the request on the target end system.

An example of creating such an extension is given in the accompanying Best Practices document [LIS, 13c].

6.1.2 Proprietary Data Elements

Extensions to the data model are only permitted where the IMSExtension class is available. Within the Outcomes data model only the ‘LineItem’, ‘Result’ and ‘ResultValue’ classes can be extended. The extension takes the form of a Name/Type/Value triple. Many extension fields can be added but hierarchical structures must be emulated using the appropriate delimited notation in the ‘Name’ field. This triple consists of:

· Name – the name assigned to the extension field (this is a string that can support any naming convention);

· Type – the data-type that is to be used for the value (this is used for interpreting the associated value);

· Value – the data value for the extension (the value is supplied as a string).

6.2 Profiling the Service

Move to top

This Service can be profiled. In general, Profiling is used to:

a) Refine which Interfaces are used and which operations are supported for each Interface;

b) Refine the data models (see the 1EdTech Application Profiling guidelines for more details on how data models can be profiled [APG, 05a][APG, 05b]).

Valid Profiles must be restrictive i.e., optional features can be removed or constraints increased but new features must not be added. A Profile of this service is made by annotating the UML supplied with the documentation for the specification.

Appendix A – Summary List of Service Status Codes

The summary list of status codes that can be returned by the different operations through the StatusInfo object is given in Table. A1.1. The key to the entries is: ‘Y’ denotes the code may be returned by that operation. A blank entry means that the code cannot be returned by that operation.

There is a set of status codes that must be supported by each of the Outcomes Management Service operations. These codes are described in Table A1.2.

Table A1.2 Common status codes for the service operations.

Status Code	Explanation of the Cause of the Code
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=unauthorizedrequest’	The source system is not authorized to make this request of the target. The reason for the refusal can be one of several causes.
‘CodeMajor=Failure’ ‘Severity=Status’ ‘CodeMinor=targetisbusy’	The target end-system received the request but is busy and cannot process the request. The request should be resubmitted.
‘CodeMajor=Failure’ ‘Severity=Error’ ‘CodeMinor=linkfailure’	There has been a failure in the end-to-end system communications mechanism and so the request has not been delivered.
‘CodeMajor=unsupportedLIS’ ‘Severity=Status’ ‘CodeMinor=*’	This service in LIS is not supported by the target system. Every system that implements any part of the LIS specification must return this status code for a service component in LIS that is not supported.
‘CodeMajor=unsupportedLISoperation’ ‘Severity=Status’ ‘CodeMinor=*’	This operation is not supported by the target system. Every system that implements any part of the LIS specification must return this status code for an operation that is not supported in a supported service.

Appendix B – Vocabularies

B1 Set of Defined Vocabularies

Move to top

The vocabularies listed in Tables B1.1, B1.2 and B1.3 are the default set maintained under the 1EdTech Vocabulary Registry [SDN11, 06]. It is the responsibility of an implementation to ensure that it is using the correct and latest versions of the vocabulary files. Changes to the default vocabularies are permitted; this results in the creation of a new vocabulary that should be registered with 1EdTech. As part of a profiling process entirely new vocabularies may be defined to replace the default set.

The set of external vocabularies that are used in this information model are listed in Table B1.1, B1.2 and B1.3.

The language code/country code combination used to identify the language for a piece of text is an enumerated external 1EdTech vocabulary that captures the full set of entries from RFC4646.

B2 Using Vocabularies for the Metadata Class

Move to top

The Metadata class consists of attributes:

· metadataNameVocabulary – identifies the vocabulary that contains the reference set of fieldName values for the meta-data[2];

· metadataTypeVocabulary – identifies the vocabulary that contains the reference set of fieldType values for the meta-data. The value for this attribute is the same as the ‘vocabIdentifier’ of the VDEX instance for this vocabulary;

· metadataField – contains the set of triples (fieldName/fieldType/fieldValue) for each meta-data entry.

The value in the ‘fieldName’ must be from the vocabulary (identified using the metadataNameVocabulary attribute). The value in the ‘fieldType’ must be from the external vocabulary containing the permitted set of external field types (as listed in the metadataTypeVocabulary attribute). The value in the ‘fieldValue’ is the metadata value itself. Nested values are possible using a dot notation in the ‘fieldName’ e.g., for LOM this could be ‘general.keyword.string’, etc.

B3 Using Vocabularies for the IMSExtension Class

Move to top

The IMSExtension class consists of attributes:

· extensionNameVocabulary[3] – identifies the vocabulary that contains the reference set of fieldName values for the extension;

· extensionTypeVocabulary – identifies the vocabulary that contains the reference set of fieldType values for the extension. The value for this attribute is the same as the ‘vocabIdentifier’ of the VDEX instance for this vocabulary;

· extensionField – contains the set of triples (fieldName/fieldType/fieldValue) for each extension.

The value in the ‘fieldName’ must be from the vocabulary (identified using the extensionNameVocabulary attribute). The value in the ‘fieldType’ must be from the external vocabulary containing the permitted set of external field types (as listed in the extensionTypeVocabulary attribute). The value in the ‘fieldValue’ is the extension value itself. Nested values are possible using a dot notation in the ‘fieldName’ cf. for meta-data.

Appendix C – File-based Data Exchange

The 1EdTech Bulk Data Exchange Management Service [BDEMS, 13] is used to exchange bulk Outcomes and related information. The Outcomes information is exchanged by placing multiple LineItemRecord, ResultRecord and ResultValueRecord structures within a bulk data container. Figure C1.1 shows the key class structure and the associated definitions are provided in Section 5 of this document.

Figure C.1 Outcomes class diagram for file-based data exchange.

Note that separate binding instance validation files will be used for containing the description of LineItemRecords, ResultRecords and ResultValueRecords within a file. This ensures that only the required data structures are contained in the corresponding binding validation files.
