Hi Jacek,

I'm currently working on a complete english translation of the first draft of my technical note on mapping SAWSDL/WSDL-S into UDDI.
This note also defines a mapping of WSDL 2.0 into UDDI based on the WSDL 1.1 mapping defined by the OASIS committee.

I'm pretty sure there will be a lot of changes that will be needed (and huge english errors) so I'll submit this document to the list as soon as possible.

Dear Pierre, 

the working group has not discussed any relationship between UDDI and
SAWSDL. However, I believe this is an important issue and the final
specification should in some way touch this topic, therefore I just
added an issue [1] that will be considered by the group. 

However, I cannot guarantee that the group will be able to consider this
issue earlier than after it publishes Last Call on the main parts of the

Below, please find my more concrete responses to your message, but 
I mostly request clarification because I'm not all that familiar with
UDDI yet.

I think both us and the WS-Description Working Group would be interested
in this mapping, please consider letting them know on their mailing list .

Can you please clarify what you mean by type-related semantic
annotations, and how you would map them to UDDI?

It seems that matchmaking based on the semantic annotations of inputs
and outputs is indeed among the possible uses for SAWSDL, but again,
I'll need clarification on what you mean with the "hard mapping" into
UDDI structures.

Please pardon my ignorance about UDDI,
