Description and comments

RDFa is a technique for semantic data in XHTML using the RDF abstract data model, but with a syntax that works easily alongside existing markup. In common with Microformats and GRDDL, it shares the underlying idea of encoding semantic (machine processable) information in the markup for human-readable content. One might view RDFa as a kind of generalized microformat (though in some respects it goes against the microformats principle of only addressing specific problems - see DefiningImageAccess/Standard/Microformats for more discussion).

Strictly, to validate, RDFa needs to be used with XHTML 2.0, which is not yet widely used. This (too) is a cause of some tension with the Microformats community.
