RDF in Attributes (RDFa)

Overview

RDFa is a specification for attributes to express structured data in XHTML. The rendered, hypertext content of XHTML is reused by the RDFa markup, so that publishers don't need to repeat significant data in the document. Tools can extract that structured data and generate RDF triplets for further reuse. RDFa can be considered as another serialization format for RDF, alongside RDF/XML or Turtle.

Recommended Reading

The official RDFa documents, published in 2008, include a RDFa Primer. The community also maintains a separate RDFa Wiki for further information.

A number of textbooks have been published on RDF, RDFS, and on Semantic Web in general. Please, refer to a separate page listing some of those, as maintained by the community. That list also includes references to conference proceedings and article collections that might be of general interest.
