The most common elements in the Data Archive are Studies, Questionnaires, Questions, Datasets, and Variables. There are also other elements in the archive, but they usually relate to one of these 5 basic elements. The following diagram shows the basic relationship between these elements.
The Data Archive interface makes it easy to browse the metadata by navigating from an element to related elements. For example, while looking at a Question, it is simple to navigate to the related Questionnaires, or the related Variables.
