RDF in Attributes (RDFa)
RDFa is a specification for attributes to express structured data in HTML5, XHTML, and any XML application. The rendered, hypertext content of (X)HTML or XML 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 triples for further reuse. RDFa can be considered as another serialization format for RDF, alongside Turtle, RDF/XML, or JSON-LD.
The latest version of the RDFa Recommendation is 1.1, completed in August 2013. The RDFa 1.1 suite consists of RDFa Core, that defines the general RDFa concepts; of RDFa Lite, that defines a subset of the general RDFa Core, a subset that is very easy to learn and covers a large percentage of the use cases; and of the mappings of the general RDFa Core concepts to HTML4 and HTML5 (including XHTML5) and to XHTML 1.1. The suite is completed by an RDFa Primer.
The official RDFa documents, published in 2013, include an RDFa Primer. The community also maintains a separate RDFa Information site for further information, test suite, and an additional list of tools.
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.
