Wednesday June 20 2001 UDDI Updated (A Bit) The UDDI 2.0 specifications were published on Monday June 18 at uddi.org, a major version update for the Universal Description, Discovery and Integration protocol. However, for an upgrade from 1.0 to 2.0, anyone following the UDDI specification's progress might have expected some major feature enhancements to UDDI. If you were, you're likely to be disappointed. UDDI 2.0 offers some limited enhancements to the search API, some internationalization enhancements, and some minor modifications of the data model to allow for the description of more complex business entities. This feels more like a point-version update - an UDDI 1.1 - than a major version release. And UDDI 1.0 was not without its problems. As this week's lead article, by Monica Copeland, shows, business adoption of UDDI has been tentative, and has not yet fulfilled the potential which UDDI hopes to offer. The enhancements to UDDI 2.0 seem destined to reinforce UDDI's position as a global yellow-pages for looking up telephone numbers and e-mail addresses, rather than offering an upgrade to its capabilities as a web services directory. There is more going on behind the scenes than in these changes to the public view of UDDI (its data structures and its API), and the two specifications which made up UDDI 1.0 have grown to four documents now, with two new specifications dedicated to how UDDI registry operators will share data and synchronize their databases. This trend - towards broader co-operation and building a future infrastructure of many UDDI registries - is clearly reflected in the change in editorial lineup on the new specifications. UDDI 1.0 was drafted by Microsoft, IBM and Ariba. UDDI 2.0 has seen SAP take up positions on the spec editing team (largely replacing Ariba), and a host of other companies providing contributors, including Oracle, Compaq, Intel, Fujitsu, Verisign, and Sun, as well as HP, who are setting up a third root UDDI directory later this year. Requirements gathering for version 3.0 of the UDDI spec is underway right now in Atlanta, GA, at the UDDI Advisor conference. Attendees are drawn from the 280 UDDI community members.
