RDFa or Resource Description Framework in Attributes is a W3C Recommendation that adds a set of attribute-level extensions to HTML, XHTML and various XML-based document types for embedding rich metadata within web documents. The Resource Description Framework (RDF) data-model mapping enables the use of RDFs for embedding RDF subject-predicate-object expressions within XHTML documents. RDFa also enables the extraction of RDF model triples by compliant user agents.

The RDFa community runs a wiki website to host tools, examples, and tutorials.
