DAML-S, UDDI and WSDL

I've read some of the papers on how DAML-S can be used to enhance UDDI
and WSDL.  If I want to use DAML-S to perform service discovery and
description of web services without having to create a DAML-S query
engine, is it correct to say that I need to 1) create a DAML-S to UDDI
matchmaking engine to enhance the UDDI registry with semantic search
capabilities, and 2) also create a DAML-S to WSDL converter so that the
semantic description can be published in the UDDI registry?

 

Or if I just have 2) (DAML-S to WSDL mapping), then I can just do a UDDI
query on this WSDL file to find the semantic information.  In other
words, do I need to have both 1) and 2) in order to make the semantic
service discovery and description work?

 

Also, are any of these tools available for 1) and 2)?

 

Thanks.
