UDDI like most directory services is mostly useful for those that helped design it.
The .NET Visual Studio use of UDDI is quite helpful when you are developing consumer applications against published UDDI Web Services, which I believe is the point. Obviously if you are building a Web Service and you are building the consumer application to interact with the Web Service then UDDI doesn't make a lot of sense....I have seen major companies use UDDI to provide a lookup of the internal Web Service they restrict to their own applications....doe. Further I know at least one portal company that jury rigs a kludge UDDI to lookup the entry point for a customer web service, only to use the UDDI to populate an internal configuration value for the URL to the entry point....huh? Why force the customer to provide a UDDI to the customer's web service WSDL? Doesn't the customer know the URL to the WSDL? Michael Oliver AppsAsPeers LLC 7391 S.

As far as I can see there's a huge gap between the reality of what can be done using UDDI and the marketing concept behind it (which seems to be that you can have your programs automatically look up and connect to services). Where UDDI starts to make sense to me is when you have standardized interfaces to particular types of services - then the dynamic lookup and use is actually possible. I don't know of any types of services that are actually standardized in this manner, though. Perhaps ebXML is the missing piece of the puzzle here. Without interface standardization, simple web-page directories of services (such as XMethods and the like) seem far more useful than UDDI. This is not knocking UDDI - I think it's a great tool, I just don't see any real use for it. :-) I'd love to be corrected on this if I'm overlooking something. - Dennis Dennis M.
