Mapping external taxonomies and ontologies into UDDI

In view of our discussion regarding a standard 
for external taxonomies (item 5.1 in our agenda) if you have the chance you may 
wish to have a look at the early work of some Carnegie-Mellon researchers 
(especially page 8):
http://www-2.cs.cmu.edu/~softagents/papers/Essw.pdf
I have not met Dr. Sycara yet, but her 
work may be very useful to us. I still don't have a good grasp of what they 
are doing, and I am not sure I fully agree with this complex approach, but it 
appears to me that their work is a particular example of what could be done by 
mapping external taxonomies into UDDI representations. 
Obviously the above 
example was an undertaking focussing on a specific external system, and on 
establishing its ability to map into the UDDI spec as it was at its early 
stages of development. DAML is also now evolving into OWL. We will therefore 
need to look into the following:
1. Find out how UDDI v2 and v3 relate to OWL 
based on the above mapping model and similar models
2. Extend this 
examination beyond DAML/OWL to Topic Maps (After looking at the very useful 
information Max has sent out to us, I feel that Topic Maps are far more 
promising)
3. Try to find what functionality we can incorporate in UDDI v4 in 
order to make this kind of mapping better and more flexible
