We have two choices; either use URIs for this, or invent some other "Universal Thing Identifier" schema. I hope we can ignore the third "choice", which is do some ridiculously impossible inference based on context, probability, and voodoo. You need some basic level of confidence in your ability to identify things before getting into the voodoo. > obviously don't have it, since we can't agree whether the string > "http://www.ibm.com/" denotes a way to access information, a > collection of information, a linguistic expression of some > information, or a company about which one can get some information! Well, on the "obviously we don't have it" part, I am not sure I agree. The thing I agree on is that there are people who argue that an http: URL is a car. There are people who say that "bad" means "good". And there are even people who think that these two facts prove that words are meaningless and URIs identify nothing. URIs are the "words" of the Internet. Words mean things. I am quite happy to use URIs to identify things. > messier semantic web. I don't think anything will break, but a large Actually, it will. If we allow someone to use "bad" when they mean "good", and don't require that they disambiguate, then we have no meaning at all. We might as well not even use identifiers. If we do not stick with the meaning that http://www.microsoft.com is a web page, then we make it possible that someone could make an assertion about http://www.microsoft.com when they really mean http://www.ibm.com. If it is up to the listener to disambiguate something as basic as a noun, then there are no nouns. It is the responsibility of the speaker to choose the correct nouns. It is the option of the listener to reify, if possible, but the main burden of responsibility lies on the shoulders of the speaker. Even Umberto Eco, the father of interpretive semantics, has said "I was starting the dialectic between the right of the texts and the right of their interpreters. I have the impression that in the course of the last decades the right of the interpreters has been overstressed." I agree with Eco. > consensus. It's also not clear this matter much outside of RDF. It matters for any triples (or as Seth uses, quintuples) that make an assertion. It matters less for RDF (IMO), since RDF makes it easy for the car people to disambiguate responsibly.
