Definition
- The Resource Description Framework (RDF) is a language for representing information about resources in the World Wide Web.
- Originally RDF was primarily intented to represent metadata 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. However, by generalizing the concept of a "Web resource", RDF can also be used to represent information about things that can be identified on the Web, i.e. the semantic web.
