If the question is philosophical and concerns the Web (in any form)
this is probably the best place I can imagine to ask it. If you're
looking for practical advice you may have to spend a lot of time
reading between the lines...

The discussion here two (three?) weeks ago on "After XQuery, are we
done?" touched on many of the questions you ask here. A side issue
that must be solved is "naming" vs. "pointing". Michael Kay's
question as to why does one have to use any pointers at all to tell an
application that <postcode> means something hit's to the heart of the
problem. One either has to have root Ontologies and a long chain of
discovery (local knowldge domain caches would help), or pointers (in
the abstract sense, read URL if you want to get into that debate).
Pointers become domain specific or a maintenance issue.

Yes, for people who want to use XML.... ;-) I can't really answer
this one other than to note that syntax seems to be the least of the
problems.

As I said, syntax seems to be the least of the problems. The problem
is complex, the solutions will be complex, but every time I start
diving into any of this my head spins. There's got to be a better
way...

I agree with Michaels comments, in particular the bit about the bottom
up approach being applicable. The other thing I'll note is that the
Government has a vested interest in driving much of this. One can
think of an Ontology infrastructure as being the Web equivalent of the
federal interstate system. It's a problem that needs to be solved on
the national scale and there is economic benefit as well as all the
indirect social (security, medical, you name it) benefit. However,
the idea of the government being in charge of how universal knowledge
discovery is done scares the heck out of me, some form of public
oversight with real clout is needed.
