Metadata is data about data. It is useful if you are organising a lot of questions, you can use metadata to describe each question. You can add Metadata to any question by right clicking while your mouse is over the question in the Action Pane and selecting the add option. The metadata properties window will open and you can add four metadata elements to the question:
Title
Description
Identifier
Keywords
The question will then appear with the blue circle information icon below it in the quiz tree.
The Title you use in the metadata will be used as an identifier for the question in the Question Writer Tracker as well as when setting conditions to evaluate scores for Custom Feedback.
