The resource description framework (RDF) is a specification being developed by the World Wide Web Consortium (W3C) to create a cross-platform standard for managing meta information. Metadata, or data about data, has many uses, including cataloging websites, creating intelligent agents, automating sitemapping, and managing digital signatures of intellectual property. RDF is designed to provide an infrastructure to support metadata across many Web-based activities. RDF will use the eXtensible markup language (XML) so that all other tools being built around XML will be able to provide a uniform and interoperable exchange across the Web.
