The Semantic Web

Les Orchard over at 0xdecafbad has a good summary of the semantic web

There are some other great references at the World Wid Web Consortium, the Semantic Web Community Portal, and at infomesh.

There is also an article in the May 2001 issue of Scientific American by Tim Berners-Lee, James Hendler and Ora Lassila.

Thanks to Michel V for the link.
