Maybe I'm just being obtuse, but most of the URN schemes I've seen
don't have that "x-" and so long as the naming authority is going
to make it impossible to create non-x domains (as apart from the
DNS where there are millions) I guess I'm simply in protest. From
what I heard at Sun (from those trying to gain a registered domain)
the idea is that there'd only be dozens of domains, not thousands.
That's not going to work. I want my own domain. I suppose I protest
"x-" because it's sort of like "alt." on usenet. I'd they'd made
it "urn:x:" rather than "x-urn:" this might seem different (what's
really in a name anyway?).

It's XML. That to me is a big deal. In Ceryle I deal with HTML
as plain text, XHTML as XML.

No, you'd have the Semantic Web.
There's my proposal of using <meta> elements to contain enough
information to make that not a problem. You'd harvest 2 million
XHTML elements with enough metadata to actually form the basis
of the "Semantic Web," which would then be a practical possibility,
whereas the W3C thinks they're going to get people to stick RDF
on their web pages. Good luck.

I *can* imagine web authors doing something like that, and it would
be harvestable. It uses all the best of our existing technologies;
we already have what we need. The rest is marketing hype to gain
funding for new work, IMO (there's an article related to this
subject re: funding for AI in Red Herring this month).

One of the sad things about corporations is that despite
their name they have no corpora, no body responsible for
their actions. They are therefore free to do whatever is
the will of those who control them, and can transmogrify
as necessary, like ghosts, to thwart those who might try.
