For real-world case studies, the closest that I can offer is what I described in my September 2003 ebXML Forum article titled "UDDI and ebXML Registry: A Three-Tier Vision[2]", in which I describe how UDDI and ebXML Registry can indeed be utilized in a complementary fashion, on multiple levels (tiers). In that article I also describe a pilot project for Tier 1, "Reachthrough Capability". > Also it seems that ebXML can do everything that UDDI can and more (except be > a lot easier to implement than ebXML), is this the case? Not sure about which is easier to implement (would depend on the product, of course) - but in essence, one may consider ebXML Registry to be a "superset" of UDDI in ways that are described in [1]. > Is this just an > accidental effect of trying to provide for all business processes?

(which is really anything you'd like, as ebXML Registry's information model is abstract and designed for any type of content). More specifically, do you need to store (vs. simply register) artifacts in a repository? UDDI does not have a repository capability, but ebXML Registry does. Also, how does the product landscape look for UDDI? How does it look for ebXML Registry? These are only some of the factors involved in such a decision. There is an open-source ebXML Registry SourceForge project called "ebxmlrr" that you can find at [3]. Farrukh Najmi of Sun Microsystems is the leader for this project, and he is on this listserv.

That scenario is certainly possible, given the capabilities of the 2 specifications. It all comes down to your business needs, including whether or not you can/want to procure 2 products instead of one. Hope this helps.
