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.

All Rights Reserved. The CategorizedStatsitic complexType is the container for information about an item statistic that consists of multiple values e.g. IRT Dispersion Parameters. 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. The OrdinaryStatistic complexType is the container of an item statistic that consists of a single numeric value. Usage data, most commonly item statistics, do not form part of an assessmentItem directly because they always relate to some context or domain in which the statistics are valid. Therefore, this specification defines a separate class for describing these statistics. The map is defined by a set of mapEntries, each of which maps a single value from the source set onto a single float. 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. A simple type used to represent a single value of any baseType as defined by the assessment variable data model.
