This is discussion we just had on the "After XQuery, are we done?"
thread: starting from the question of how to glue separate documents
together.  Given the twists and turns that thread took I wouldn't hold
out a lot of hope for solving this any time soon.

If all the components for the Semantic Web existed you'd arguably
already have universal relationship discovery. If you build all the
components needed for universal relationship discovery you arguably have
the Semantic Web. Two sides of the same coin; no need to debate which
one comes first since they'll both be boot strapping each other into
existing for a long time yet.

The first two are easy compared to the third?

The idea of w3c level ontology roots seems to pop up every once and a
while. I believe you're asking for something a little more local and a
little less heavy weight than ontology traversal to locate resource
descriptors so that you can query for document contents, but that's the
crux of the problem: anything universally applicable needs to solve
universal scale problems. At the moment I'd have to conclude that you
need to be careful what you ask for, you might get it...
