I added generic XPath's to this which indexes ALL references between
objects, regardless of where they are. I am all giggly now, because the
result is just mindbogglingly cool. Now I can do search-replace of
object references (e.g. "delete object X and replace all references with
object Y") and easily find how many links I have to a particular page
(e.g. "find all references between X and Y where X is a Link and Y is a
Page"). Stuff like that. Things that would have been IMPOSSIBLE with our
old technology, and certainly very very difficult with either just an
RDBMS or even XML-database. Now it's just plain trivial. I could even
implement garbage collection of objects in the database by using this
(e.g. "find all objects with no references and remove them. Repeat until
none are left").

Very nice. :-)
