I'm not talking about "most applications", which will have specialized
editors written for them, I suppose, at least if it's really
annoying.  I'm talking about turning a huge variety of "applications"
into a semantic web that can be traversed by a single application.  It
may not be that a single "universal" application (a la the web browser
for the ordinary web) is appropriate, but what I'm looking for is
evidence that apps for the semantic web are coalescing (acquiring each
others' capabilities) rather than proliferating.

Um, that is an proposed explanation of *why* the defects I perceive
are there; it's not an attempt to support the claim that they *are*
defects.  So even though it mentions people, it's not ad hominem.

I *do* have the relevant background.  So why are you classing my
arguments with those hominems over there?

Same difference.  Either way, putting the types into the literals is a
bad idea.

Hm.  I think I know an absurdum when I see one....

... I see.  A trivial problem looks like the above.  An interesting
problem would look like, oh, 1MB of the above?

That's Just AI, and has nothing to do with a semantic web as such.  As
you've pointed out, the semantic web is about connecting up the items
in a massively distributed database.  My "trivial" problem has that
nature, and your "interesting" one does not (as stated).

Um, no.  All of those can be done by specialist software and
databases.  Where's the need for a semantic web here?

Again, a special application that works by passing around tokens.
They happen to have internal structure, but they could just as easily
have been PGP keys which also allow chasing a trust graph.  Honestly I
don't see where the semantic web appears.

The semantic web will be a reality when three applications FOAF +
OpenID, FOAF + Dublin Core, and OpenID + PAM can be pasted together to
give login privileges to any author who I have cited in one of my
papers, and this can be done in a syntax as simple as yer average home
