The W3C’s Semantic Web Deployment Working Group has published the first working draft describing RDFa’s syntax: RDFa in XHTML: Syntax and Processing. This is a significant step for RDFa — congratulations to the group for their effort. RDFa provides a standard way to embed semantic content expressed in RDF in HTML documents. More precisely, it lets one add RFD content in XHTML documents. RDFa will open up more use cases for the Semantic Web and may offer a way to embrace other approaches to adding semantic information to Web documents such as microformats.
