h4. Resource Description Framework (RDF)

*RDF* is a language for representing information about resources in the World Wide Web. It is particularly intended for representing meta-data about Web resources, such as the title, author, and modification date of a Web page, copyright and licensing information about a Web document, or the availability schedule for some shared resource.

RDF is based on the idea of identifying things using Web identifiers (called Uniform Resource Identifiers or URIs), and describing resources in terms of simple properties and property values. This enables RDF to represent simple statements about resources as a graph of nodes and arcs representing the resources, and their properties and values.
