RDFa

As Danny reported, it seems that Joost has triggered a race for using RDF in video metadata: ZDNet has reviewed the alpha version of Seesmic, an online video applications using RDF “as the foundation”, supporting vocabularies such as FOAF, SIOC, DC, MPEG-7 (cf. Multimedia Vocabularies on the Semantic Web report for further details). As an aside: Seesmic supports RDFa!

Over in the public HTML list, a posting by Peter Krantz caught our eye with this line:

I am working in a project right now where RDFa solves a lot of problems for over a 100 government organizations.

Nice to see RDFa gaining traction!
