Well, if you baulk at things as intangible as real numbers, how about points on a line, or spatial regions (eg., for a concrete example, geographical infomation bases)? There are far more of these than could possibly be represented by any finite collection of URIs. This isn't necessarily a _practical_ problem, but it certainly undercuts any suggestion that RDF(S) is capable of representing "everything". As Shakespeare might have said, there are more things in Heaven and Earth than are dreamt of in RFC 2396 ;-) Cheers, Miles -- Miles Sabin InterX Internet Systems Architect 27 Great West Road +44 (0)20 8817 4030 Middx, TW8 9AS, UK msabin@interx.com http://www.interx.com/
