Overview

MetadadataProvider objects represent a particular "stream" or "source" of Metadata in the repository. They resemble Aggregators in that they define a grouping of objects, but carry additional semantics and restrictions because they may only contain Metadata objects, and any given Metadata object must be provided by exactly one MetadataProvider.
