RDFa

- RDFa in XHTML: Syntax and Processing: W3C Recommendation 14 October 2008 http://www.w3.org/TR/2008/REC-rdfa-synta...

RDFa, Resource Description Framework with attributes is a set of extensions recommended for XHTML to support metadata in any XML document. The recommendation includes only syntax. Pre-defined context specific vocabularies can be used to define attributes.
Support for RDFa allows web site owners to publish specific data about events, products, services, people and more. That data can be read and understood by search engines and other software. Yahoo, Google and Bing provide enhanced search results for various vocabularies expressed using RDFa.
Incorpoation of RDFa data in web pages is a stepping stone to Tim Berners-Lee's original vision of the web of meaning also referred to as the Semantic Web.
