One semantic addition to UDDI that I can think of (but I don't yet see
how to really make it work) would be to provide the ability to describe
the semantics of the associations that are created by adding categories
to a service. 
In a bit more detail: 
I have a taxonomy of things registered in UDDI, and I have a service.
I register my service, adding a category from my taxonomy to the service
(to its category bag).
This creates an association between my service, and a category of my
But what association is that? Is it an ISA link? Is it "is instance of"?
"Is it "is provider of"?
It would be nice to know.

	Yes, that's the question I am asking myself. 

	Let me try to turn around my original question and see if we can
get a better understanding of the issue. The paper "Importing the
Semantic Web in UDDI" describes the mapping of the DAML-S Profile to
UDDI data structures. From the diagram in Fig. 5, it seems that most of
the Profile information is simply mapped to existing UDDI structures, so
that what is already available in UDDI is sufficient for a faithful

	So a question could be: are there other elements of the DAML-S
Profile (not shown in that picture) that currently do not easily map and
that would benefit from the creation of new data structures in UDDI?
Alternatively, is it useful to come up with a more complex Profile that,
while currently difficult to map, would easily map with the addition of
new data structures to UDDI and would provide more reasoning power?
