This document is a part of the IMS Global Question and Test Interoperability (QTI) v2.2 specification. It introduces QTI-specific metadata. In QTIv2.2 the QTI-specific metadata is aligned with the IEEE Learning Object Metadata (LOM) in accordance with the IMS Metadata Best Practice and Implementation Guide for [IMD, 06]. The IEEE LOM standard defines a set of metadata elements that can be used to describe learning resources, but does not describe assessment resources in sufficient detail. The application profile provided in this document therefore extends the IEEE LOM to meet the specific needs of QTI developers wishing to associate metadata with items (as defined by the accompanying Item Information Model). QTIv2.2 further extends this to enable the description of tests, pools and object banks.
The IMS QTI Metadata v2.2 is used in conjunction with the following documents:
This QTI Metadata v2.2 specification supersedes the QTI v2.1 versions. The QTI Information Model is bound to an XML Schema Definition (XSD). This document and the accompanying XSD is generated using the IMS Global Binding Auto-generation Tool-kit (I-BAT) [I-BAT, 06]. The additions made in v2.2 are:
The IEEE LOM documentation describing the Information Model [LOM, 02] and the IMS XSD Binding [IMD, 06] should also be used with this specification.
The structure of the rest of this document is:
| 2. Information Model | The Information Model description for the QTI Metadata. This description uses a profile of UML to represent the structure of the data model; |
| 3. XSD Binding | This is the description of the binding of the data model to XML and the corresponding XSD that is used to validate QTI Metadata instances. This description includes an explanation of the relationship between the UML representation and the XSD that is produced through transformation of that representation; |
| 4. Extending and Profiling the Data Model | Identification of the ways in which the data model can be extended (both in terms of the extending features and proprietary extensions to the model) and how this base specification, and its model-based description, can be profiled to produce derivative specifications; |
| Appendix A Modelling Concepts and Terms | An overview of the model driven approach, the concepts and the terms used by IMS to create the data model representations (based upon a profile of UML), the corresponding set of bindings and the accompanying documentation (including this information model); |
| Appendix B Binding Terminology | An overview of the concepts and the terms used by IMS to create theXSD-based bindings representations and the accompanying documentation. The XSD binding is auto-generated from the UML representation to ensure full consistency between the information model and binding; |
| Appendix C XSD Listings | The listing of the QTI Metadata XSD that should be used to validate instances of the data exchange. |

Figure 2.5.3 - ScoringMode class definitions.
Note that the LOM-defined 'Structure' and 'AggregationLevel' fields are not recommended by this profile.
One of the values given for the identifier must have an entry that matches the identifier of the associated item, test or object bank.
The title must have a value that matches the value of the title attribute of the associated item, test or object bank. The language used to interpret the title is taken from the language attribute of the associated item, test or object bank.
There must be one value for each of the languages referred to by the language attributes on the associated assessmentItem, test or object bank and its 'bodyElements'.
When transforming item metadata records with no description into systems that require a value for this field, the 'title' of the item, test or object bank should be used to set the value of the description.
When transforming item metadata records with no keywords into systems that require a value for this field, the 'title' of the item, test or object bank should be used to derive a set of keywords. It should be noted that LOM specifically indicates the use of classification for the description of subject area, and specifies that general.keyword 'should not be used for characteristics that can be described by other data elements'.
See comment in status below for important information about the use of this field.
It is anticipated that systems for handling assessment resources would prefer to draw from wider vocabularies than the one defined by [LOM, 02]. However, in order to facilitate the transformation of metadata instances to systems that require the use of the LOM vocabulary for this field it is recommended that the version is used to achieve the tracking of items, tests and object banks through more complex production processes. The classification category may also be used to express the status and availability of assessment resources.
Usage as defined by [LOM, 02].
A globally unique label that identifies this metadata record.
Usage as defined by [LOM, 02].
Metadata records that adhere to this profile are conforming LOM instances, therefore references to both this specification and LOM are applicable. The appropriate references are QTIv2.2 and LOMv1.0. References to other schemas to which the metadata instance conforms are also permitted.
There are two approaches to providing multilingual information in LOM-based metadata records which can be used separately or in combination. The first is to translate the metadata on a field-by-field basis providing each field value as a set of strings, each individually language tagged. The alternative is to generate multiple equivalent metadata records and use this language field (on the meta-metadata category) to set the default language for the whole record. This profile prefers the latter approach, metadata records conforming to this profile should not provide multilingual values to individual fields within the record.
Note that the LOM-defined Requirement, Installation Remarks and Duration fields are not recommended by this profile.
There should be at least one instance of format with the value 'text/x-imsqti-item-xml', 'text/x-imsqti-test-xml' or 'application/xml'.
Usage as defined by [LOM, 02].

Usage as defined by [LOM, 02].
Note that the LOM-defined 'Interactivity Type', 'Interactivity Level', 'Semantic Density', 'Intended End User Role', 'Typical Age Range' and 'Difficulty' fields are not recommended by this profile.
QTI objects are designed to be reusable in a variety of assessment scenarios. Therefore, the LOM-defined values self assessment and exam are forbidden. If the standard LOM vocabulary is used then only the values exercise or questionnaire should be used to describe an item.
This is used to provide an educational context for the value given in typical learning time.
In the context of a QTI object, the typical learning time is interpreted as the length of time the candidate would normally be allocated to complete the object. It is not a time limit, however, when building a time-limited test from an item bank the typical learning times of the selected items may be added together to estimate the expected duration of the test and used to calculate a time limit for the test if required.
Item, test or pool objectives should be included in this field if required.
Usage as defined by [LOM, 02].
Note that the LOM-defined cost and copyright_and_other_restrictions fields are highly problematic, and that a more detailed rights description language is necessary to adequately express the often complex rights issues surrounding resource creation and reuse. However, the vast majority of application profiles mandate the rights category, and it is therefore recommended for use within this application profile.
Care should be taken when an item depends on a (shared) media file with its own metadata to ensure that restrictions on the use of the media file are reflected in the overal rights description of the item itself.
Usage as defined by [LOM, 02].
Usage as defined by [LOM, 02].
Usage as defined by [LOM, 02].
This category is used to express the relationship between items and tests, fragments and the objects that include them and individual relationships between items.
A number of relationships between items may be described without extending the LOM vocabulary. However, a new vocabulary element has been introduced to allow one of the more complex inter-item relationships commonly expressed in item banks. In addition, interpretations of some LOM vocabulary elements are provided. It should be noted that each target should have a new relationship instance. The terms are:
Usage as defined by [LOM, 02].
Usage as defined by [LOM, 02].
Usage as defined by [LOM, 02]. The preferred solution for the description of an item's subject area is to used the LOM classification category with the value classification.purpose = "discipline". This allows the use of any recognized or bespoke subject classification scheme such as the top level(s) of the Library of Congress Classification (LCC) and Dewey Decimal Classification (DDC), or institutional, regional or national curriculum classifications, as specified under classiciation.taxonPath.source. For more detailed description of topics within subject areas, the value classification.purpose = "idea" may be used with further levels of LCC, DDC or subject-specific classification schemes. The classification category may also be used to describe the visibility and availability of items beyond the limited vocabulary provided by LOM lifecycle.status. The use of custom schemes for classification enables repository administrators to capture all the information they need to capture, using the terms most appropriate for that institution. There may be multiple instances of the classification category, enabling detailed classification of assessments by subject area and association of an assessment with a number of different subject areas or topics.
The XSD binding is described using a set of tables derived from the UML representation and a set of XML code snippets. The binding description consists of:

There are no schematron rules used in this XSD binding of the specification.
The binding of the IEEE LOM is based upon the IMS Metadata v1.3.2 XSD [IMD, 06]. This is a 'loose' binding of the IEEE LOM information model i.e. it permits extensions and does not enforce any of the default enumerated vocabularies.
The IMS Metadata XSD is located at: http://www.imsglobal.org/xsd/imsmd_loose_v1p3p2.xsd. The namespace is 'http://ltsc.ieee.org/xsd/LOM'. The QTI-specific entries should occur within the 'lom' element i.e. the root structure of the LOM binding (the actual child instance can occur at any point within the 'lom').
The QTI Metadata specification contains NO exension points. Any proprietary extension is non-conformant. The behavior of a system that receives a QTI Metadata instance that contains proprietary extensions is undefined (however a system should handle such violations in a controlled manner).
The QTI Metadata may be contained within a LOM instance. In such cases the LOM instance may have other extensions added to it; the QTI Metadata is inserted within a LOM extension point. The processing of other LOM extensions is beyond the scope of this specification.
This specification may be profiled: for example, the IMS Accessible Portable Item Protocol (APIP) v1.0 specification includes a profile of QTI Metadata (as well as several profiles of other IMS specifications). A profile must be a formal subset of the base specification. This ensures that, with the exception of namespace/schema location changes, any instance which is compliant to the profile MUST also be compliant to the base specification. This means that a profile must only increase the constraints on the properties of the data model. For example, an element with a multiplicity of [0..1] can have this changed to [1..1] but NOT [0..*]. Proprietary extensions are ONLY permitted as defined by the base 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, 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.
Table A1.1 provides the key to the descriptions of data model diagrams.
| Feature | Definition and Usage |
|---|---|
| Data Model Package | Each data model description is enclosed in a UML Package that has the stereotype of « dataModel » under which is the name of the data model diagram being described. Only one logical data model can be described. |
| DerivedType Class | This is a class that is identified by the stereotype « DerivedType » under which is the name of the data-type. A derived class is one that is derived either from another derived class or a PrimitiveType class. |
| Enumeration Class | This is a class that is identified by the stereotype « Enumeration » under which is the name of the enumeration data-type. The enumeration class consists of the list of tokens that are the permitted values of the assigned attribute. |
| Enumerated List Class | This is a class that is identified by the stereotype « EnumeratedList » under which is the name of the enumerated list data-type. The enumeration list class consists of the list of tokens that are the permitted values of the assigned attribute. A list of tokens is permitted using comma separation. |
| PrimitiveType Class | This is a class that is identified by the stereotype « PrimitveType » under which is the name of the primitive data-type. A PrimitiveType is one of the many base data-types on which a data model can be built (see Appendix A1.3 for the set of primitive types that are available). |
| Selection Class | This is a class that is identified by the stereotype « Selection » under which is the name of the data-type. The selection means that only one of the listed attributes make occur in an instance. If this is an abstract class then multiple iterations of the instance may occur and the multiplicity of the attribute defines the constraints on the number of times the attribute can occur in the full instance. If the stereotype and associated name of the class are in italics this denotes the class is abstract. |
| Sequence Class | This is a class that is identified by the stereotype « Sequence » under which is the name of the data-type. The sequence means that the listed attributes must occur only in the order of the attributes listed on the class. The associated multiplicity defines the number of times the attribute may occur consecutively in the instance. If the stereotype and associated name of the class are in italics this denotes the class is abstract. |
| Unordered Class | This is a class that is identified by the stereotype « Unordered » under which is the name of the data-type. The unordering means that the listed attributes may occur in any order but the associated multiplicity for the attribute must be followed (when binding to XML this requires the use of Schematron rules to enforce the multiplicity). If the stereotype and associated name of the class are in italics this denotes the class is abstract. |
| List Class | This is a class that is identified by the stereotype « List » under which is the name of the data-type. A list class is one in which the associated instance will consist of a list of objects that conform to the permitted data-types of the list (the superclasses for the list class). The terms in the list are separated by a space. |
| Union Class | This is a class that is identified by the stereotype « Union » under which is the name of the data-type. A union class is one in which the associated instance will consist of a objects that conform to the any of the permitted data-types of the union (the superclasses for the union class). |
| Characteristic Description | Many classes contain a set of characteristics (the set of characteristics are listed under the stereotype « Characteristics »). Each characteristic description consists of the scope, name, data-type and multiplicity (see Appendix A1.3 for a more complete description). Note that when bound to XSD/XML, a characteristic is mapped to an XML attribute. |
| Attribute Description | Many classes contain a set of attributes (the set of attributes are listed under the stereotype « Attributes »). Each attribute description consists of the scope, name, data-type and multiplicity (see Appendix A1.3 for a more complete description). Note when bound to XSD/XML, an attribute is mapped to an XML element. |
| Composition Arrow | This is an arrow with a filled diamond head to indicate that the child class is a composite structure of the parent class i.e. the child class only exists within the context of the parent class. This association allows complex structures to be constructed with common subcomponents. |
| Generalization Arrow | This is an arrow with a white arrow head to indicate the class/superclass relationship. The arrow points in the direction of generality i.e. from the class to the super class. |
Table A1.2 provides the key to the descriptions of the data class tables.
| Category | Definition |
|---|---|
| Class Name | The name given to the class being described. |
| Class Type | The nature of the class. This is described as a "Container [...]" or "Abstract Container [...]". The value of "..." being (see Appendix A1.1 for the meaning of these values):
|
| Parents | This is the list of classes that contain the class being described as either the type of a child characteristic or attribute. In the case of a Root Class the entry is also labelled as "Root Class". |
| Derived Classes | The set of classes that are derived from this class (there may be none). The entries are linked to the corresponding class descriptions. |
| Super Classes | The set of super classes from which the class being described is derived (there may be none). The entries are linked to the corresponding class descriptions. |
| Characteristics | Lists the set of characteristics for this class. The list of characteristics includes those that are inherited. Each characteristic is linked to the corresponding characteristic description table. |
| Children | Lists the set of attributes for this class (the only other permitted associations are generalizations). The list of children includes those attributes that are inherited. Each child entry is linked to the corresponding attribute description table. The nature of the relationship between the children is defined by the stereotype of the parent class i.e. the class type. If the child is in italics this denotes a reference to an abstract class and that an instance would NOT contain a child of that name but would be replaced by a complex set of children as defined by the associated abstract class. |
| Description | Contains descriptions relating to the class and its properties and relationships. |
Table A1.3 provides the key to the descriptions of the data attributes/characteristics for the data classes.
| Category | Definition |
|---|---|
| Attribute Name or Characteristic Name | The name given to the attribute or characteristic being described. If the name is in italics this denotes an abstract attribute or characteristic. |
| Data Type | This is the data-type of the attribute or characteristic (if this is in italics it denotes an abstract class). The data-type can take many forms:
|
| Value Space | The range of valid values for this attribute/characteristic (including any default value). If the value space is unspecified, it is not known or is not important. This value space must be defined in terms of the associated data-type. |
| Scope | This is the scope of the attribute/characteristic with permitted values of:
|
| Multiplicity | A property of an attribute/characteristic indicating the number of times it may be used or appear in a given class instance. The values of this property are expressed as a range or shorthand for a range using the notation:
|
| Description | Contains descriptions relating to the attribute/characteristic and its values space. |
Table A1.4 provides the key to the descriptions of the enumerated vocabulary classes. These are vocabularies that will be contained within the binding form itself
| Category | Definition |
|---|---|
| Term | The vocabulary token itself i.e. the vocabulary entry. |
| Definition | The meaning of the term and how it should be used. |
Table A1.5 provides the key to the descriptions of the external vocabulary classes. These are vocabularies that will be contained in some independent format e.g. using the IMS VDEX.
| Category | Definition |
|---|---|
| Term | The vocabulary token itself i.e. the vocabulary entry. |
| Definition | The meaning of the term and how it should be used. This consists of the "Caption" and "Description" of the vocabulary term. The caption is used to provide a human readable label for the term. |
Table A1.6 provides the key to the descriptions of the import classes.
| Category | Definition |
|---|---|
| Import Class Name | The name of the class. |
| Parent Classes | The list of parent classes, and the associated children, that use this imported class. Each class and attribute name has a link to its corresponding tabular description in the information model. |
| Description | The description of how the class is used within the data model. |
Table B1.1 provides the key to the descriptions of UML to XSD attribute mapping tables.
| Feature | Definition and Usage |
|---|---|
| Attribute Name | The name of the attribute (these are the attributes listed in the class identified by the « Roots » stereotype). |
| UML Class | The name of the class, the type of the attribute, in the UML diagrams (each class will have an associated stereotype label to denote its modelling interpretation). If the information model description is contained within the same document, this value is hot-linked to that description. |
| XSD Name | The equivalent name of the UML attribute name in the XSD i.e. the XML element name. |
| XSD Type | The XSD type - this will always be "Element". |
| XSD Data Type | The data-type in the context of the XSD. This is hot-linked to the corresponding description table in the binding. |
Table B1.2 provides the key to the descriptions of UML to XSD class mapping tables. This table shows the relationship between the two modelling components:
| 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", "Core" or "Derived" depending on the nature of the class. The list of attributes (mapped to XML elements) and characteristics (mapped to XML attributes) will be identified as either "Attributes" or "Characteristics". |
| Data Type | The data-type has several permitted values:
|
| Multiplicity | The multiplicity of the child attribute/characteristic. The value for the Class itself is "-N/A-". The multiplicity values are:
|
| XSD Name | This is the equivalent name of the UML artefact in the XSD. In the case of a "Derived" class the UML attribute may be used to define constraints on the primitiveType and so may not have visibility in an instance. In this case the name entry will be "[ No XML instance visibility ]". |
| XSD Type | The XSD data-type. For the Class this will have either the value "ComplexType" or "SimpleType" or the statement "There is no equivalent derived complexType. This is a logical class that is used to identify a namespace constraint.". For the attributes the value is either "Element (Global)" or "Element (Local)" depending on the scoping. For the characteristics the value is either "Attribute (Global)" or "Attribute (Local)" depending on the scoping. In the case of a "Derived" class the UML attribute may be used to define constraints on the primitiveType and so may not have visibility in an instance. In this case the type entry will denote the type of restriction i.e. MinLength, MaxLength, WhiteSpace, MinInclusive, MaxInclusive and Pattern. |

Table B1.6 provides the key to the descriptions of XSD element tables.
| Feature | Definition and Usage |
|---|---|
| Namespace | The namespace for the XSD element. |
| Diagram | This diagram consists of three types of linked blocks. Straight link lines denote XML sequence whereas diagonal lines denote XML selection/unordered. The block forms are:
|
| Type | The data-type for the element. This will possible entries are:
|
| Type Hierachy | The identification of the superclass upon which this type is based (the superclass is shown on the top line). This indicates the source of the inherited set of XML elements and attributes for the element. |
| Properties | The set of properties for the element including (these will not be shown for Global elements):
|
| Used by | The features in the XSD that make use of this global or root element. These features are listed under the heading "ComplexTypes". Each of the entries is linked to its formal description table. |
| Facets | The permitted set of facets for the content i.e. the ways in which the content is further constrained. This row is only present if there are associated facets. The set of permitted facets are:
|
| Model | The set of child elements. This is an ordered list of elements (as per the sequence in the data-type complexType) and accompanied by their multiplicity. Links to the corresponding declarations are supplied. In the case where the type is an enumeration or primitiveType then the value is "N/A". The value may also be "Empty" to indicate that no children are permitted. If the element is imported i.e. from an external XSD, only the URL for that XSD will be given. |
| Attributes | The set of global and local XML attributes for this complexType (if the element is imported i.e. from an external XSD, only the URL for that XSD will be given). Links are made to the associated tabular definitions. Each attribute is described by:
|
| Schematron Rules | The set of schematron rules to be applied for the element grouped as:
|
| Source | The equivalent XSD code for the declaration of the element. This includes the multiplicity and default values for the element. See the W3C XSD documentation for the description of the permitted contents for this declaration. If the element is imported i.e. from an external XSD, only the URL for that XSD will be given. |

| Facets | The permitted set of facets for the content i.e. the ways in which the content is further constrained. This row is only present if there are associated facets. The set of permitted facets are:
|
| Used by | The features in the XSD that make use of this complexType. These features are listed under the headings "Root Elements", "Elements" and "ComplexTypes". Each of the entries is linked to its formal description table. |
| Model | The set of child elements. This is an ordered list of elements (as per the sequence in the complexType) and accompanied by their multiplicity. Links to the corresponding declarations are supplied. In the case where the type is an enumeration or primitiveType then the value is "N/A". The value may also be "Empty" to indicate that no children are permitted. In some situations the value may be "None" denoting that there are no children defined e.g. for a base class from which other classes are derived and which may have children as part of the extension. |

| Version Date: | 1st August, 2016 |
| Status: | IMS Final Release |
| Summary: | This is the definition of the data model and the corresponding XSD binding to be used to support the exchange of QTI Metadata. This data model defines the object model for the exchange of a QTI-specific Metadata and also explains how to place this information within the context of an IEEE Learning Object Metadata (LOM) XML Schema Definition (XSD) XSD binding. The data model and XSD binding is described using the IMS profile of UML to support the IMS model driven specification engineering method. |
| Revision Information: | This document supercedes IMS QTI Metadata Information Model and XSD Binding v2.1. Version 1.0.1 is a document consistency update with the QTI ASI 2.2.1 XSD. |
| Purpose: | This document is made available for adoption by the public community at large. |
