Embedded RDF is a pattern for enriching content by interweaving existing XHTML markup with RDF. The method used requires no new markup so the XHTML can still be validated, is fully CSS compliant and will not affect browser behaviour. In this presentation I’ll explain the advantages of visible metadata, not repeating yourself and reusing existing technologies. I’ll show several detailed examples of how the embedding works using schemas such as DOAP, FOAF and vCard and how the RDF can be extracted using XSLT and GRDDL. I’ll also demonstrate how browser extensions such as Piggy Bank can detect and act on the embedded RDF. Finally I’ll summarise how much of the RDF model can be embedded and explore the limits of the embedding method.
