As I've been following all the stuff about URIs and global names, etc. I've been reminded of many years of fighting the issues of symbol grounding in my misguided youth (Pat, I can only claim 22 years of AI, so you win)... However, I'm puzzled by Stefan's claims that we cannot deal with a lot of things without "true" URIs and some of the other things I've been reading here. Here's a stab at something - to me the most important idea in DAML is the "equivalento" sort of mechanism -- it let's a first user define a desiognator for Boston, a second user defines a different URI for Boston, and a third comes along and says - they are the same (the issue of whether to believe the third person is irrelevant to this discussion - all multi-person representation will need some sort of caveat emptor mechanism or we'll all be in infinite loops forever) So, I say on one page that (forgive me for not using RDF, DAML or the like - this doesn't need the syntactic stuff) jah:ProfessorHendler is at the URI http://www.cs.umd.edu/~hendler/#hendler-daml Someone else has that darpa:JimHendler is at URI http:"mailto:jhendler@darpa.mil" If I now put somewhere in web space that EquivalentTo jah:ProfessorHendler darpa:JimHendler then we have a nice network, if you believe me we've appropriately grounded the symbols, etc. btw, you're free to have your own completely different notion of what a James Hendler is, but if you want to share it with me, you'll need to "name" it, and then I'll need to be able to find it on the web, and also to check my KBs to see if I know something it is equivalentTo. Hey, I like the web -- let's use it! -Jim H. (URI = PGP-key:123451234543212345432...)
