I don't think that Semantic Web is the extension of the current Web. It could be and surely some aspect of it is being build on it. However the Web may not be the best technology to extend for the Semantic Web. Semantic Web is a vision where data can be shared verified and searched much better than now.
To my knowledge, the Semantic Web does not exists, yet. Or, does it, and I missed it?? Ervinn 04:23, 6 May 2009 (UTC)
