Humph! I see far more than these 2 "schools of thought". For example,
mnemonic naming doesn't strictly fall into either of these categories.
My wife and I have a child overdue now, so I am abnormally keen to matters of
naming (we don't know the sex, nor do we have Igbo names picked out, though we
have English ones).
As far as I'm concerned naming is one of the most fundamentally inexplicable
things people do, and there is no way of lumping approaches to naming into
such neat camps.

This is true of names arrived at by any method, if people who use the names
choose to give the name such an ontological (warning: philosophical, not
compsci usage) load.
A name is what you make of it. Some people have stronger beliefs of the role
of a name in meaning than others, but this is a function of the user, not the
coiner of the name.

Again, I don't see how this is unique to functional names.

Yes. So what does this have to do with RDF?

I never heard this from the RDF activity. Do you have a citation? I have
heard it from some of the more, er, overenthusiastic boosters of RDF, just as
I've heard silly things from some boosters of markup.

I lost the trail somewhere.
