Definition

An instance of this DRM class provides a characterization of the data set being described, including its intended use and limitations. In the documentation for this class, the phrase “the data set” refers to “the data set being described by the given <DRM Description> instance”. This, in turn, refers to the object tree rooted at the aggregate of the <DRM Description> instance. If a <DRM Description> is shared by multiple aggregate objects, then “the data set” refers to the collection of object trees rooted at its various aggregates.
