An Introduction to the Resource Description Framework
Eric J. Miller
The Resource Description Framework (RDF) is an
infrastructure that enables the encoding, exchange and reuse of
structured metadata. rdf is an application of xml that imposes needed
structural constraints to provide unambiguous methods of expressing
semantics. rdf additionally provides a means for publishing both
human-readable and machine-processable vocabularies designed to
encourage the reuse and extension of metadata semantics among
disparate information communities. the structural constraints rdf
imposes to support the consistent encoding and exchange of
standardized metadata provides for the interchangeability of separate
packages of metadata defined by different resource description
communities.
