If we can give TBL the benefit of the doubt, I think it is possible that the "semantic web" means--at least--something. At a minimum, surely it is a web of atoms of information each component of which can be universally addressed, and where the arcs between each node (or the node itself) has some label, and that if one can trace back along these arcs (including schemas to bring the labels into the web too) to well-known datums (IYKWIM) then one can do more or less useful things with that web. This is not AI, this is just a big fat database. Is dog has a collar; a dog is an animal; an animal can have a name; a dog can have a collar, a collar can have a name tag; a nametag can have a name: start from the dog and do a search of everything connected to it to try to find the name. AI comes into the heuristics in navigating around a database of information. The question is how much the technology we are building actually promotes that: an XML Schema is not "semantic" in the kind of sense above--it gives information for types not meanings or properties. This is one objection to identifying namespaces and schemas too much: it actively prevents a semantic web (in that sense.) Cheers Rick
