The semantic web assumes two separate layers of Google is incredibly dependent on several forms of metadata: * Every time you publish a web page that contains a hyperlink to another page, you are asserting that "the target page is interesting to me". That is metadata in every sense of the word. * When you click through a Google search result, you are asserting that "this search result was more relevant than the others". Google captures this metadata randomly. * When you browse pages, you are asserting that "this page is interesting enough to spend time on". If you have Google toolbar installed, and the appropriate opt-in selected, Google captures this metadata * When a certain number of pages around the world link to a particular page, that page is given a higher "page rank". This is metadata in every sense of the word. > Sites can and will lie with their metadata. Google, by You seem to be assuming that metadata is only something which is published by a page author about his or her own page. Metadata about content which you own is no more interesting than hyperlinks to content which you own. The point of semantic web is to permit anyone to publish metadata about anyone else, the same as the point of the web was to allow anyone to hyperlink to anyone else. In fact, you can think of the WWW as a version if the web which had only one term in the vocabulary: href. You also seem to be assuming that metadata is something which must be published by a human. Again, I would argue that some of the most interesting metadata available is implicit, and needs no human interaction to maintain.
