RDF (Resource Description Framework)
Resource Description Framework (RDF) is a foundation for processing metadata; it provides interoperability between applications that exchange machine-understandable information on the Web. RDF emphasizes facilities to enable automated processing of Web resources. RDF can be used in a variety of application areas; for example: in resource discovery to provide better search engine capabilities, in cataloging for describing the content and content relationships available at a particular Web site, page, or digital library, by intelligent software agents to facilitate knowledge sharing and exchange, in content rating, in describing collections of pages that represent a single logical "document", for describing intellectual property rights of Web pages, and for expressing the privacy preferences of a user as well as the privacy policies of a Web site. RDF with digital signatures will be key to building the "Web of Trust" for electronic commerce, collaboration, and other applications.
Resource Description Framework provides a technique for describing resources on the web. The RDF specification is made up of two W3C documents:
- RDF Model and Syntax Specification (http://www.w3.org/TR/REC-rdf-syntax/) : W3C Recommendation
This document introduces a model for representing RDF metadata as well as a syntax for encoding and transporting this metadata in
a manner that maximizes the interoperability of independently developed Web servers and clients.
- RDF Schema Specification 1.0 (http://www.w3.org/TR/rdf-schema/) : W3C Candidate Recommendation
This specification describes how to use RDF to describe RDF vocabularies. The specification also defines a basic vocabulary for this purpose, as well as an extensibility mechanism to anticipate future additions to RDF.
