Document Name: IMS OneRoster Resources Service REST/JSON Binding v1.2

Revision: 1st July 2021

toc | top

Abstract

The IMS OneRoster (OR) standard addresses the exchange of student data (primarily about people, courses, enrollments and grades) between different educational systems for the specific needs of K-12. The primary use-case is the exchange of data between a Student Information System (SIS) and Learning Management System (LMS). In OR 1.2, the service has been split into three core services:

This OR 1.2 Resources Service provides the ability to manage the allocation of resources to classes, courses and users. It does NOT enable access to the resources themselves. The resource data provides the information that describes the resource and its relationships to classes and/or courses and/or users. The service description includes the definition of the data formats that are exchanged using a set of service operations. In this document the binding implementation as a REST/JSON service is described.

1. Introduction

This Section is NOT NORMATIVE.

1.1. Scope and Context

This document is the OneRoster 1.2 Resources Service REST/JSON Bindinging and as such it is used as the basis for the implementing the OR Resources Service Model. The key related documents are:

This service model and this REST/JSON binding is described using the Unified Modeling Language (UML) based upon the IMS Global Model Driven Specification approach and the associated modelling toolkit [I-BAT, 06]. This means that this specification is based upon the concepts of:

Key artefacts produced as part of the REST/JSON binding description are the associated OpenAPI files based upon the OpenAPI Specifications version 2 [OAS, 14] and version 3 [OAS, 17].

1.2. Conventions

All sections marked as non-normative, all authoring guidelines, diagrams (with the exception of the UML diagrams), examples, and notes in this specification are non-normative. Everything else in this specification is normative.

The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC 2119]. This means that from the perspective of conformance:

The Conformance and Certification Guide for this specification may introduce greater normative constraints than those defined here for specific service or implementation categories.

The SHOULD/SHOULD NOT/RECOMMENDED statements MUST NOT be used in any document, or section of a document, that is responsible for defining the information model and/or the associated bindings and/or conformance and certification.

1.3. Changes in the Resources Service 1.2

The only changes made in this new version are:

1.4. Structure of this Document

The structure of the rest of this document is:

2. REST Endpoints An explanation of the relationship between the logical service operations (as defined in the OneRoster Resources Service Model) and how these are realised as the corresponding set of REST endpoints (including the set of query parameters that are permitted);
3. Using the Endpoint Parameters A detailed explanation of how the permitted set of query parameters should be used to control the volume and type of information that will be supplied by the service provider;
4. Security Framework The underlying security framework within which this REST/JSON binding is designed to operate. This includes the details about authentication and how the payload integrity may be protected;
5. UML to JSON Mappings The description of how the JSON payloads are derived from the equivalent UML data model definitions [OR-RES-SM-12]. Each UML class and attribute is mapped to the equivalent JSON object and property.
6. JSON Payloads Examples of the set of JSON payloads that are sent by the consumer (the request) and returned by the service provider (response). These examples are focused on the expected structure of a request/response and do not include actual payloads;
7. OpenAPI Description A detailed explanation of the structure of the OpenAPI files that are produced as part of the specification documentation. The associated JSON and YAML files are supplied in Appendix B;
8. Extending and Profiling the Binding An explanation of how the service can be extended, using the permitted points of extension and/or profiled. Profiling is the process by which the specification is tailored to a specific set of market/domain requirements;
References The set of cited documents, normative and informative, that are used to support the technical details in this document;
Appendix A Model Binding Terms and Concepts An overview of the model driven approach, the concepts and the terms used by IMS to create the service model REST/JSON binding definitions (based upon a profile of UML) and the accompanying documentation (including this binding);
Appendix B OpenAPI Listings The listings of the OpenAPI(JSON) and OpenAPI(YAML) files that have been created to define the REST/JSON binding in a machine-readable format i.e. conforming to the OpenAPI 2.0 specification;
Appendix C JSON Schema Listings The listings of the set of JSON Schema files (based upon IETF JSON Schema Draft 7) that have been created for the validation of the set of JSON payloads that are exchanged as part of this service.

2.5 Service Discovery

A Service Provider MUST provide a localized version of the OpenAPI file (version 3 JSON file format) to enable service discovery [Security, 21].

This file MUST be located at: "...hostname.../ims/oneroster/resources/v1p2/discovery/".

The OpenAPI file MUST have the name: "onerosterv1p2resourcesservice_openapi3_v1p0.json".

Therefore the full URL for this service discovery file is: ...hostname.../ims/oneroster/resources/v1p2/discovery/onerosterv1p2resourcesservice_openapi3_v1p0.json

3. Using the Endpoint Parameters

This SECTION is NOT NORMATIVE.

3.1. Pagination

For requests of collections e.g. the response for the 'getAllResources()' call, there is a danger of data overload. To avoid this, implementations should adopt a pagination mechanism. Pagination is controlled via two parameters that are appended to the request:

An example of a request to return the first 10 resources in a collection:

    GET https://imsglobal.org/ims/oneroster/resources/v1p2/resources?limit=10

An example of a request to return the second 10 resources in a collection:

    GET https://imsglobal.org/ims/oneroster/resources/v1p2/resources?limit=10&offset=10

It is RECOMMENDED that implementations pass the total resource count in collection back to the requester. This MUST be provided in the custom HTTP header: X-Total-Count.

It is RECOMMENDED that implementers pass back next, previous, first and last links in the HTTP Link Header.

Consider the requests for the example where 503 resources exist in the collection. The pagination is in units of 10.

    Link:

    <https://imsglobal.org/ims/oneroster/resources/v1p2/resources?limit=10&offset=20>; rel="next",
    <https://imsglobal.org/ims/oneroster/resources/v1p2/resources?limit=3&offset=500>; rel="last",
    <https://imsglobal.org/ims/oneroster/resources/v1p2/resources?limit=10&offset=0>; rel="first",
    <https://imsglobal.org/ims/oneroster/resources/v1p2/resources?limit=10&offset=0>; rel="prev"

3.2. Sorting

It should be possible for collections, e.g. the response for the 'getAllResources()' call etc. to be returned in a sorted order. It should be possible to sort the collection based on any single data element in the core description of the resource. Sort requests MUST make use of the reserved word "sort" (?sort= data_field), and optionally the reserved word orderBy for which:

An example of a request to ask for a list of resources sorted into ascending title order:

    GET https://imsglobal.org/ims/oneroster/resources/v1p2/resources?sort=title&orderBy=asc

Sorting should conform to the use of the Unicode Collation Algorithm [UNICODE, 16] when using the relevant comparisons.

If the consumer requests that the data is to be sorted by a non-existent field, data MAY be returned in the service provider's default sort order or an error response MAY be returned.

When sorting/ordering is requested on a property that is an array, the first value in the array is used as the basis of the sorting/ordering.

To sort/order on the properties of nested objects, (for example, with metadata properties), a dot-notation approach MUST be used. The format for this is:

    ?sort=<Nested_Object>.<Property>

3.3. Filtering

For the calls that request collections e.g. 'getAllResources()' call, it should be possible to filter collections for elements matching a certain criteria. It should be possible to filter collections based on any data element in the core description of the resource.Filter requests MUST take the form:

    ?filter=<data_field><predicate><value>

or

    ?filter=<data_field><predicate><value><logical><data_field><predicate><value>

The data fields that can be used are those present in the class definition being filtered. So for example in 'resources', it MUST be possible to filter on: 'sourcedId', 'title', 'vendorResourceId', 'dateLastModified', etc.

Predicates MUST be chosen from those listed below:

Values MUST be enclosed within single quotes and they MUST be handled as case insensitive. When the response is returned it is the receiving system that should consider whether or not case-sensitivity is important.

The <logical> parameters allow more complex queries to be created. For version 1.0, it is RECOMMENDED that logical operations are limited to " AND " and " OR " (note the surrounding white space at each side) and that there is only one such operator used in any filter i.e. a single 'AND' or a single 'OR' in the filter. A single white space must occur before and after the parameter.

To query on the properties of nested objects, (for example, with metadata properties), a dot-notation approach MUST be used. The format for this is:

    ?filter=<Nested_Object>.<Property>

Note then when querying on metadata, the property is loosely typed. An example or a request to find resources with a 'status' of 'active' is:

    GET https://imsglobal.org/ims/oneroster/resources/v1p2/resources?filter=status='active'

URL encoded as:

    GET https://imsglobal.org/ims/oneroster/resources/v1p2/resources?filter=status%3D%27active%27

Filter queries MUST be URL encoded.

An example of a complex query for all resources with a status='active' AND dateLastModified>'2016-12-12T00:00:00Z' is:

    GET https://imsglobal.org/ims/oneroster/resources/v1p2/resources?filter=status%3D%27active%27%20AND%20dateLastModified%3E%272016%3D12%3D12T00%3A00%3A00Z%27

When filtering on objects that are arrays the application of the filter depends on the nature of the comparison. So in the case of filtering on, for example, a 'role' field when the value of the field is 'role1,role2,role3' the following filters would return:

This means filtering using the '=' has 'AND' semantics and the '~' has 'OR' semantics. Filtering rules should conform to the use of the Unicode Collation Algorithm [UNICODE, 16] when using the relevant comparisons.

If the consumer requests that data be filtered by a non-existent field, NO data is returned and the server must provide the associated transaction status code information of:

3.4. Field Selection

For the read collection calls, such as 'getAllResources()', it should be possible for requesters to select the range of fields to be returned. By default, all mandatory fields from the core description of the resource MUST be returned. If any fields are specified in the request then the implementation should return those fields AND ONLY those fields i.e. the multiplicity constraint rules for an element are overridden. Any field or fields from the Data Model MAY be requested.

Field selection request MUST make use of the reserved word 'fields'. The value of fields is a comma delimited list of the fields to return. An example of a request message to ask for a list of Resources returning only the 'sourcedId' and 'title':

    GET https://imsglobal.org/ims/oneroster/resources/v1p2/resources?fields=sourcedId,title

If the consumer requests that data be selected using non-existent field, ALL data for the record is returned. If the consumer requests that data be selected using a blank field the request will be treated as an invalid request. The server must provide the associated transaction status code information of:

4. Security Framework

This Section is NORMATIVE.

The information in this section is taken from the IMS Security Framework [Security, 21]: that document describes the security approaches to be adopted in all IMS specifications.

4.1. Transport Security

As the service will be exposing personal data related to students and their grades, it is important that only authorized users have access to that data. Further, data exchanges should be encrypted to ensure that packet sniffing cannot be used to read the data in transit.

All Requests and Responses MUST be sent using Transport Layer Security (TLS). Exchange of the signed certificates for endpoints between clients and servers is beyond the scope of this specification. Implementers of clients and servers are advised to look at the various 3rd party certificate signing services in order to obtain signed certificates.

Support for TLS 1.2 and/or TLS 1.3 is REQUIRED and SSL MUST NOT be used.

4.2. Authorization

The use of OAuth 2.0 Client Credentials with the Bearer Token obtained using the mechanism described in [RFC 6749] (Section 4.4) is REQUIRED. Details of this are given in the IMS Security Framework [Security, 19].

Authorization will use the OAuth 2.0 Client Credentials Grant mechanism. In this mechanism the client can request an access token using only its client credentials (using the consumer key and secret information) when the client is requesting access to the protected resources under its control, or those of another resource owner that have been previously arranged with the authorization server. In this approach the client issues a client authentication request and receives in response an access token. Issuing of an access token is defined in Section 5 of [RFC 6749].

The request for an access token, including three scopes (scopename1, scopename2 and scopenamex) takes the form of (this uses TLS):

        POST /token HTTP/1.1
        Host: server.example.com
        Authorization: Basic czZCaGRSa3F0MzpnWDFmQmF0M2JW
        Content-Type: application/x-www-form-urlencoded

        grant_type=client_credentials&scope=scopename1%20scopename2%20scopenamex
        

The inclusion of scopes is REQUIRED and the set of scopes available for this service are defined in the following subsection. The authorization encoding is produced using the consumer key and secret. Note that the request for an access token MAY use a HTTP GET request.

The authorization encoding is produced using the consumer key and secret. Success results in the granting of the access token with a response of:

        HTTP/1.1 200 OK
        Content-Type: application/json;charset=UTF-8
        Cache-Control: no-store
        Pragma: no-cache

        {
            "access_token" : "2YotnFZFEjr1zCsicMWpAA",
            "token_type" : "bearer",
            "expires_in" : 3600,
            "scope" : "scopename1 scopename2 scopenamex"
        }
        

The recommended default value for the "expires_in" is 3600s. The authorization server MUST provide the scopes which are made available (either all or a subset of the scopes supplied in the request).

The client utilizes the access token to authenticate with the resource using the HTTP "Authorization" request header field [RFC 2617] with an authentication scheme defined by the specification of the access token type used, such as [RFC 6750]. An example of the use of the bearer token is:

        GET /resource/1 HTTP/1.1
        Host: provider.example.com
        Authorization: Bearer 2YotnFZFEjr1zCsicMWpAA
        

NOTE: This exchange assumes that TLS is used to secure the link.

6. JSON Payloads

This Section is NOT NORMATIVE.

6.1 "getAllResources" Request Payload

There is no payload for this request.

6.2 "getAllResources" Response Payloads

6.2.1 Response Payloads for the HTTP Codes (200)

A tabular description of the response payload is shown in the Table below.

Table 6.2.1 - Tabular representation of the JSON payload for "200" response messages for a "getAllResources" operation.
Property Name Multiplicity JSON Data-type Description
    resources [0..*] Array [ Object ] The set of contained resource identfiers.
            sourcedId [1..1] String All Objects MUST be identified by a Source Identifier. This is a GUID i.e. a unique system interoperability identifier for an object. This is the GUID that SYSTEMS will refer to when making API calls, or when needing to identify an object. It is RECOMMENDED that systems are able to map whichever local identifiers (e.g. database key fields) they use to the corresponding SourcedId. The sourcedId of an object is considered an addressable property of an entity and as such will not be treated as Personally Identifiable Information (PII) by certified products. Therefore, as a part of certification, vendors will be required to declare that they will notify customers via documentation or other formal and documented agreement that sourcedIds should never contain PII in general, but particularly users. This means that if a customer includes a student name in an enrollment.sourcedId, it will not fall to any certified product to protect the enrollment.sourcedId as PII, or even the userSourcedId field in the enrollment record.
            status [1..1] Enumeration All objects MUST BE either 'active' or 'tobedeleted'. Something which is flagged 'tobedeleted' is to be considered safe to delete. Systems can delete records that are flagged as such if they wish, but they are not under any compulsion to do so. NOTE: In v1.1 the enumeration value of 'inactive' was removed and so for backwards compatibility all such marked objects should be interpreted as 'tobedeleted'.
            dateLastModified [1..1] String (Format: date-time) All objects MUST be annotated with the dateTime upon which they were last modified. This enables requesters to query for just the latest objects. DateTimes MUST be expressed in W3C profile of [ISO 8601] and MUST contain the UTC timezone.
            metadata [0..1] Object All objects CAN be extended using the Metadata class. This specification is silent on what implementers may consider to be appropriate extensions.
                    extensions [0..*] Set of Proprietary Properties The form of the extension will be determined by the associated binding (for examples see [OR-IMPL-12]).
            title [0..1] String A human readable title/label for the resource.
            roles [0..*] Array [ Union(RoleEnumExt) ] The set of roles, types of users, who are expected to make use of the resource.
            importance [0..1] Enumeration This is an indicator of the significance of the resource i.e. primary or secondary.
            vendorResourceId [1..1] String This is a unique identifier for the resource allocated by the vendor.
            vendorId [0..1] String Identifier for the vendor who created the resource. This will be assigned by IMS Global as part of Conformance Certification.
            applicationId [0..1] String Identifier for the application associated with the resource. The nature, and how this identifier is assigned is not defined by this specification.

An example of the response JSON payload is shown in the code block below. The JSON Schema file that can be used to validate this payload is given in Appendix C1.1b.

There is no payload for this request.

6.10 "getResourcesForUser" Response Payloads

6.10.1 Response Payloads for the HTTP Codes (200)

A tabular description of the response payload is shown in the Table below.

Table 6.10.1 - Tabular representation of the JSON payload for "200" response messages for a "getResourcesForUser" operation.
Property Name Multiplicity JSON Data-type Description
    resources [0..*] Array [ Object ] The set of contained resource identfiers.
            sourcedId [1..1] String All Objects MUST be identified by a Source Identifier. This is a GUID i.e. a unique system interoperability identifier for an object. This is the GUID that SYSTEMS will refer to when making API calls, or when needing to identify an object. It is RECOMMENDED that systems are able to map whichever local identifiers (e.g. database key fields) they use to the corresponding SourcedId. The sourcedId of an object is considered an addressable property of an entity and as such will not be treated as Personally Identifiable Information (PII) by certified products. Therefore, as a part of certification, vendors will be required to declare that they will notify customers via documentation or other formal and documented agreement that sourcedIds should never contain PII in general, but particularly users. This means that if a customer includes a student name in an enrollment.sourcedId, it will not fall to any certified product to protect the enrollment.sourcedId as PII, or even the userSourcedId field in the enrollment record.
            status [1..1] Enumeration All objects MUST BE either 'active' or 'tobedeleted'. Something which is flagged 'tobedeleted' is to be considered safe to delete. Systems can delete records that are flagged as such if they wish, but they are not under any compulsion to do so. NOTE: In v1.1 the enumeration value of 'inactive' was removed and so for backwards compatibility all such marked objects should be interpreted as 'tobedeleted'.
            dateLastModified [1..1] String (Format: date-time) All objects MUST be annotated with the dateTime upon which they were last modified. This enables requesters to query for just the latest objects. DateTimes MUST be expressed in W3C profile of [ISO 8601] and MUST contain the UTC timezone.
            metadata [0..1] Object All objects CAN be extended using the Metadata class. This specification is silent on what implementers may consider to be appropriate extensions.
                    extensions [0..*] Set of Proprietary Properties The form of the extension will be determined by the associated binding (for examples see [OR-IMPL-12]).
            title [0..1] String A human readable title/label for the resource.
            roles [0..*] Array [ Union(RoleEnumExt) ] The set of roles, types of users, who are expected to make use of the resource.
            importance [0..1] Enumeration This is an indicator of the significance of the resource i.e. primary or secondary.
            vendorResourceId [1..1] String This is a unique identifier for the resource allocated by the vendor.
            vendorId [0..1] String Identifier for the vendor who created the resource. This will be assigned by IMS Global as part of Conformance Certification.
            applicationId [0..1] String Identifier for the application associated with the resource. The nature, and how this identifier is assigned is not defined by this specification.

    8. Extending and Profiling the Binding

    This Section is NOT NORMATIVE.

    8.1. Extending the Binding

    Proprietary extensions of the service are based upon three approaches:

    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.

    8.1.1. 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. A new version of the OpenAPI files should also be generated with the new operation definitions.

    An example of creating such an extension is given in the accompanying Implementation Guide document [OR-IMPL-12].

    8.1.2. Proprietary Scopes

    It is permitted to create extra OAuth 2 scopes to provide more control over the availability of various endpoints.

    An example of proprietary scopes is given in the accompanying Implementation Guide document [OR-IMPL-12].

    8.1.3. Proprietary Data Elements

    It is recognized that implementers may wish to extend the specification. The preferred mechanism for doing this is for implementers to use an extension space within the OneRoster data model, and then set their parsers to read those extension attributes. Extensions are ONLY permitted using the 'metadata' attribute within the 'Base' class.

    These extensions take the form of name/value pairs. The name is the label of the extension field, and the value is the value of the extension. For example, if wanting to show the extension of field "classification", with value "private" that was added/provided by "ims", the name/value pair is: "ims.classification" : "private".

    It is RECOMMENDED that where extensions are used, whenever possible the name/value pairs are based upon vocabulary controlled files. This eliminates a proliferation of free text equivalencies from entering the data e.g. "Florida" vs "FL", vs "Florida, USA". In such cases either the attribute, or the value (or both) MUST be a URI that references the attribute and/or value from an appropriate vocabulary file. For example:

    "http://www.nbrs.org" : "FL"

    Within the OpenAPI files, uncontrolled data extensions are explicitly prohibited by the JSON Schema definition.

    8.1.4. Proprietary Vocabulary Terms

    In this version the capability to extend the 'RoleEnum' enumerated vocabulary has been added. Each proprietary term must start with the characters 'ext:'. An example is adding the two proprietary roles of 'ext:teachingasssistant' and 'ext:principal'.

    It is essential that the capabilities of any new roles are clearly defined so that mapping between other proprietary roles can be established.

    8.2. Profiling the Binding

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

    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.

    It is strongly recommended that a profile of this specification is undertaken either by, or with the close support, of IMS Global. However, no matter who is responsible for creating the profile artefacts (documents, OpenAPI files, XSDs, etc.), it is strongly recommended that the IMS specification tools are used. This will ensure that the artefacts are consistent with the base specifications and that useful support documentation is automatically produced e.g. creation of a document that summarises the differences between the base specification and the profile. Organizations wishing to produce a profile of this specification should contact Lisa Mattson (IMS Global Chief Operations Officer) at: lmattson@imsglobal.org.

    Feature Definition and Usage
    Name The name of the UML class and the associated set of attributes and characteristics. The first row is used to describe the UML class. Camel-case is used for the attribute and characteristic names.
    UML Artefact The UML Class will be denoted as "Root" or "Core" depending on the nature of the class. The list of attributes (mapped to JSON properties) and characteristics (mapped to JSON properties) will be identified as either "Attributes" or "Characteristics".
    Data Type The data-type has several permitted values:
    • PT:... - denotes a primitive type with "..." replaced by the actual primitiveType name
    • DT:... (PT:...) - denotes a derived type of name "..." derived from the primitive type "PT:..."
    • [Enumeration(...)] - denotes an enumeration of name "..."
    • [List(...)] - denotes a list of the name "..."
    • [Union(...)] - denotes a union of one or more data-types with the name "..."
    • [Imported(...)] - denotes a class with the name "..." has been imported from another specification

    Multiplicity The multiplicity of the child attribute/characteristic. The value for the Class itself is "-N/A-". The multiplicity values are:
    • "0..1" [optional; restricted]
    • "0..*" [optional; unrestricted]
    • "1" [mandatory; restricted]
    • "1..*" [mandatory; unrestricted]
    The multiplicity will also indicate when groups of elements have variable multiplicity. In the case when a selection between groups of elements is used then this is denoted by "XOR" being displayed above the multiplicity for each of the grouped elements. Alongside the XOR is the multiplicity of the group as a whole.
    JSON Name This is the equivalent name of the UML artefact in the JSON.
    JSON Type The JSON data-type. For the Class this will have the value "Object". For the attributes the value is either "Property" or "Array of Properties" depending on the multiplicity. For the characteristics the value is either "Properties" or "Array of Properties" depending on the multiplicity.

The sourcedId of an object is considered an addressable property of an entity and as such will not be treated as Personally Identifiable Information (PII) by certified products. Therefore, as a part of certification, vendors will be required to declare that they will notify customers via documentation or other formal and documented agreement that sourcedIds should never contain PII in general, but particularly users. This means that if a customer includes a student name in an enrollment.sourcedId, it will not fall to any certified product to protect the enrollment.sourcedId as PII, or even the userSourcedId field in the enrollment record.

    Appendix C JSON Schema Listings

    C1 JSON Schemas for Payload Validation

    This is the set of JSON Schema listing that are used to validate the set of JSON payloads used by this service.

    C1.1a JSON Schema for the "getAllResources" Operation Request Payload Validation.

    No request parameters are sent for this request and so there is no JSON Schema listing.

    C1.1b JSON Schema for the "getAllResources" Operation Response Payload Validation for HTTP Codes (200)

    The JSON Schema listing is shown below (the JSON Schema is available at: https://purl.imsglobal.org/spec/or/v1p2/schema/jsd/onerosterresourcesservicev1p2-getallresources-200-responsepayload-schemav1p0.json).
