Why you need RDF?  What does it give you that plain old XML doesn't give
you in this case? An OWL link-base so that you can do off-line
relationship management perhaps? But then the problem becomes
addressing/labeling/identifiers and mapping to this link-base?  

Let me put this another way: if what's being asked for is the management
of relationships between domains then the real problem is agreeing upon
common identifiers between those domains.  Once you've got that I don't
see that it matters whether you put those identifiers in RDF or plain
old XML.  I see the value for RDF for relationship management, I don't
think I need RDF for exposing the relationships to the outside world
(but I could probably be convinced otherwise)...
