At Reboot – the “annual meetingplace for the digital community in denmark” – Ben Hammersley did a entertaining to talk on the Semantic Web. Best of all, there is a video recording of the talk and Ben has put up the slides as well giving you the chance to retroactively experience his 30 minutes talk. The are more videos available that might be worth checking out but I haven‘t seen them all yet.
Interestingly, he mentions Mac OS X “produces enormous amounts of RDF data in the background”. I have no clue what could be meant by that but I would be more than happy if somebody could shed some light on this.
