When I find >a RDF document with URIs I don't know i just ignore them. When you come across an unknown non-web term, you ask a knowledge source. If you don't want to make things different on the web, you'll try to find a knowledge source for an unknown web term or resource URI as well, won't you? > If the RDF >document was well-written it should contain rdf:seeAlso links to URLs >of RDF-documents describingthe terms. Mights this be a solution? Yeah, but we don't have an RDF document. All we start with is a URI. The problem we discussed here was how to find this document containing the description of the resource denoted by the URI (in an efficient way), or how/where to serve this document in case you are the URI owner/publisher... Of course you can say that URIs are just labels and that noone should try to find out more about resources identified by URIs, but http-URIs have 95% of what is needed for automatic resource description discovery already built in, it seems to be worth the effort to find a solution for the remaining 5% in order to help the semantic web grow faster.
