RDF is designed to provide an infrastructure supporting
Meta Data across many
WWW-based activities. RDF is the result of a number of
Meta Data communities bringing together their needs to provide a robust and flexible architecture for supporting
Meta Data on the
Internet and the
WWW. Example applications include site maps, content ratings, stream channel definitions, search engine data collection, digital library collections, and distributed authoring. RDF allows different application communities to define the
Meta Data property set that best serves the needs of each community. RDF provides a uniform and interoperable means to exchange the
Meta Data between programs and across the
WWW. Furthermore, RDF provides a means for publishing both a human-readable and a machine-understandable definition of the property set itself. RDF uses
XML as the transfer syntax in order to leverage other tools and code bases being built around
XML.
