I agree. I finally gave up on the idea of having
"descriptive" GUIDs. Many will even argue that you should
*strive* for meaningless identifiers (i.e. having no
meaning other than that of uniquely identifying the object).

I would suggest that having readable identifiers is still a
good thing, if it can be done (and I believe it can). In
your example above, you may not want to rely on remembering
that your document had guid://machine.org/2003-01-31/45, but
once you've located the document through other means, this
guid may still ring some bells...

One still needs a cataloguing system, as you point out.
