Linked Data - queryable, extensive, public data

Tim Berners-Lee has done it again. This time it's not about hyperlinked text but about queryable data. In many ways this can be seen as the public domain, social software equivalent of Stephen Wolfram's proprietary system, WolframAlpha.

It's not hard to see that open will win out over proprietary once again.

Take a look at ReadWriteWeb's post on this topic. It's an excellent roundup. They recommend starting with Tim Berners-Lees's breathless presentation at TED, so do I. I've embedded it below for convenience. Then take a look at the DBpedia website to see how you can use the material for yourself. An online paper presents the technical aspects.
