I will try to give you a short answer to your good questions.


DAML-S vs UDDI

There is no direct connection between UDDI and DAML-S, so you will not
find anywhere in their documents references to one or the other.
Nevertheless,  there is an encoding of DAML-S Profiles into UDDI
records, such an encoding is described in [1].  Using that encoding
you can register DAML-S descriptions as UDDI records in UDDI.

Also, soon we will release a DAML-S registry that will use the
semantic matching capabilities of DAML-S [2] to enhance UDDI.  The
registry is under development, but the first version will be out
soon. 

A DAML-S API for DAML-S based on Jena will hopefully available by the
end of the month.  It is currently under test.

Let me know if you have additional questions,
