    XSD Data File Information
                Author:         Colin Smythe
                Date:           12th May, 2012
                Version:        2.1
                Status:         Final Release
                Description:    This is the Platform Specific Model of the Usage Data in the IMS QTI v2.1 Specification
                                Information Model. It is this representation that is used to produce the XSD binding for
                                the IMS QTI v2.1 UsageData XSD.

                History:        This version supercedes the full IMS QTI v1.2 and QTIv2.0 specifications.

                                This machine readable file is derived from IMS Global Learning Consortium (GLC) specification IMS Question and Test Interoperability (QTI) Version 2.1
                                found at http://www.imsglobal.org/qti and the original IMS GLC schema binding or code base
                                http://www.imsglobal.org/qti.

    The targetObject is used to refer to an assessment object. This object may be an assessmentItem or some other type of object defined outside the scope of this specification, for example, an entire test. In some cases it is desirable to refer not just to the assessment object but to a specific part of that object, in which case the optional partIdentifier can be used.

Complex Type Mapping.Type

Namespace | http://www.imsglobal.org/xsd/imsqti_usagedata_v2p1
Annotations | umldocumentation
    The Mapping complexType is a special class used to create a mapping from a source set of any baseType (except file and duration) to a single float. Note that mappings from values of base type float should be avoided due to the difficulty of matching floating point values, see the match operator for more details. When mapping containers the result is the sum of the mapped values from the target set. See mapResponse for details.
