Introducing Joost Widgets (2007 talk)

introducing-joost-widgets-2007-talk-presentation

I work on structured data standards for the Web. While I was at W3C I helped get the Semantic Web project started - developing technologies and the communities that support them. Since then I've been busy applying those standards in various domains, e.g. TV, social networks, digital library - most recently search via schema.org. 

I am now working full-time at Google as a Developer Advocate.

Specialties: Semantic Web, standards, W3C, software development, Social Web, technical research, RDF, schema.org, FOAF, Google, schema.org, Microdata, RDFa.
