Well, as far as I understand UDC, you can also use a directed
relationship connector (::) - but in general you are right.

I would express the UDC number something like:

skos:Coordination
  skos:coordinationType #Relation
  skos:coordinationMember #32(Politics);
  skos:coordinationMember #91(Geography);
  skos:prefLabel "32:91"

SKOS should be able to express DDC, UDC and CC - but it must stay
simple! So what do you suggest to express CC's "U:(W)" in the next SKOS?
I must admit that I don't understand the concept of "devices" in CC. I
have seen that there is also Chronological Device (CD); Geographical
Device (GD) etc. Can you explain it?

Greetings,
Jakob
