Max,
Your UDDI entities (services, endpoints etc) are all topics from the
topic map point of view - as long as you want to say something about
them (like their relationship to one another), then you should make a
topic in the topic map that stands for the UDDI entity.

Can you not use the identifiers that UDDI assigns to each entity ? If
you are using URNs for entity identifiers, then that would seem to be a
subject address.

If you have topics standing in for entities A, B, C and D, then its a
simple association between those topics.

It depends on what you mean by "pointing" - there is no addressing being
done here, just a use of common identifiers. Also, remember that the
taxonomy part and the entity description part can be separate topic
maps. Equally, any entity relationships can be yet another topic map.

I'm not sure if I got to the bottom of your concerns, perhaps it would
help if you could give some concrete examples - perhaps point us at some
UDDI instances and explain what kind of information you would see being
in the realm of the topic map (if you have some examples of that too
that would be helpful).
