"Universal Document Identifier"

I just came accros your mention of "Universal Document Identifier" in 
http://www.w3.org/DesignIssues/Architecture.html ...

It seems to me that what is identified is not a document, but a shared
memory region, a virtual location where a document can conceptually be
stored.   Something very much like a file, actually.

So why not "Universal Filename" ?

I have a lot of trouble with this talk of URI's naming documents,
because a documents seem like static things.  Of course we get this
whole weird notion of "living documents" from this.

The popular web lingo seems to have gravitated toward the location
terminology: it's all about "visiting" "sites" with "addresses".
People have no problem understanding why they should keep their
advertised address constant; it's the idea of deep-linking (that their
site might be considered to be made up smaller, also-addressible
locations, even down to fragment ids) that hasn't, I think, really
sunk into the public consciousness.  (after all, a few clicks of
navigation isn't so bad for humans.)
