Description

A SubjectSet is a container for a set of Subjects. All of the Subjects within a SubjectSet should come from the same controlled vocabulary.

A document can be described using terms from more than one controlled vocabulary. In order to do this, you should use the Scheme attribute to distinguish between controlled vocabularies.
