Interestingly, he didn’t mention the words “Semantic Web” once during the talk, nor did he ever say “RDF” or even “URI” – instead he spoke about “names starting with ‘http’”. Cool enough, his slides had the dog food data set in them! :)
A video of the talk and a link to the slides can be found on the ebiquity blog.
