AssessmentItem:Attributes

An attribute is a characteristic of an item. An attribute has both and
 * a name predefined by the QTI specification (e.g. “Title”)
 * a corresponding value - e.g. “MCQ on the Inventor of the Jet Engine” - supplied by the item author

Attribute values are read and written by systems (e.g. delivery engines) which process QTI items.

Note that attributes are distinct from the structural components of an item - such as its stem and options. Attributes are meaningful only within a QTI environment. You cannot create your own additional attributes.

The following list shows the set of attributes predefined by the specification. Some are mandatory (you must supply a value for them); others are optional.


 * IDENTIFIER - Uniquely identifies item (Mandatory)
 * TITLE - A short descriptive title for the item (Mandatory)
 * LABEL - A short label for the item (Optional)
 * LANGUAGE - QTI supports different languages (Optional)
 * ADAPTIVE - Is this item adaptive? (Mandatory). An adaptive item can change its appearance or its scoring (or both) in response to each of the candidate's attempts. Otherwise it is a non-adaptive item (the default).
 * TIMEDEPENDENT - Will time taken to respond to the question affect candidate's score? (Mandatory)
 * TOOLNAME - Name of tool which created item (Optional)
 * TOOLVERSION - Version of tool which created item (Optional)

Example of Item Attributes
The following example shows attributes in action. The code segment below is taken from an example question (“Unattended Luggage”) in the QTI specification:-



Values, within double quotes, have been assigned to each of the four mandatory attributes - identifier, title, adaptive and timeDependent.
