Go to IBM developerworks, there are lots of info. concerning about the UDDI and the WSDL relationship. WSDL is a standard markup language to describe the web service, and the service provider has to regist it through a publich UDDI registry service. The client have to find their needed service from UDDI, and then get the access point , through proxy to bind with the related service. In general, the UDDI business service can be mapped with the WSDL service implmentation , and the tModel canbe mapped with the WSDL service interface file. so UDDI is something as a search engine but with standard description for services that can be understood by all clients and service providers.

Doug.. UDDI is more like a repository/search engine mechanism.. xmethods.org and few other are examples of the repositories where we can get the information about the services (WSDL)we are interested.. Now since UDDI is an interface the underlying implementation may vary... Currently to my understanding the underlying implementation are just distrubuted database (xmethods.org).. UDDI spec doesnt mandate any implemenation... So in the future we can see UDDI implementation to be in LDAP which IMO is a good fit for lookup services.. Hope it helps Ragu
