About
RDFa is Semantic Annotation for (X)HTML.
With RDFa, you can easily include extra “structure” in your (X)HTML to indicate a calendar event, contact information, a document license, etc… RDFa is about total publisher control: you choose which attributes to use, which to reuse from other sites, and how to evolve, over time, the meaning of these attributes.
This site tracks RDFa specifications, implementations, and news of all sorts. If you have an RDFa implementation, send us an email and we’ll be happy to announce it. (While we set up our email aliases, send Ben an email.)
For more information on RDFa, check out the RDFa Primer.
