Does anyone have any experience building topic maps in an XML database?
I'm starting a project where I have alot of entities (people, things,
resources) and alot of types of relationships (owned by, assigned to,
etc). I think (though I'm not sure) that this sort of thing can be
managed by topic maps and that there is an XML specific way to describe
them (XTM?). Would anyone have any ideas about doing this sort of
thing?

Thanks!
