The Resource Description Framework [RDF] provides a basic model to describe relationships between objects. Ultimately, it is intended to permit the representation, combination and processing of most types of metadata from Web-accessible documents or databases. However, except for representing simple metadata, its current XML-based syntax [RDF syntax] and the set of basic concept/relation types that have been defined [RDF schema] are insufficient. To make extensions, the users are required to declare new concept/relation types in "schemas" or import schemas from other users.
