Maintaining Activity: Data Activity
This is the public community/discussion list for users, implementers, or any interested parties on the RDFa specification.
RDFa is a specification for attributes that can be used with HTML (and for any XML dialect) to express structured machine-readable data within an HTML document. Like microformats, RDFa allows parts of the HTML content to be used both for rendering (to the human reader) and be part of the structured (machine-readable) data. Unlike microformats, RDFa specifies only a syntax for including structured data and relies on independently-developed vocabularies (also called taxonomies or ontologies) to provide the specific terms for given data items. RDFa permits these vocabularies to be freely mixed within a single HTML document.
Additional information may be found in the RDFa 1.1 Core specification, the RDFa 1.1 Primer, and the RDFa community wiki.
