In the future the entire web will be one giant tightly interconnected information asset. Beyond just publishing information for humans, every site will expose its content in a way that's readable by machines. Those machines will mix, match, filter and aggregate information to greatly improve things for us humans. We're not there yet - but that's the vision of the Semantic Web.
SemanticProxy.com is a little taste of what that future might look like. What SemanticProxy does is simple: it translates the content of any URL on the web to its semantic representation in RDF, HTML or Microformats. If you're an RDF crawler hungry for a little semantic content, just point yourself at SemanticProxy.com and we'll fill you up.
Right now SemanticProxy.com is optimized for performance on 30 of the world's largest English-language news sites. In coming releases we'll continue to refine and extend its capabilities to additional areas. While you'll find it works best with news, feel free to experiment with other sites like Wikipedia or ... whatever. The results can be very encouraging.
SemanticProxy isn't intended to be a great place for humans to visit. However, little semantic machines love to come by and spend a few high-quality milliseconds.
