The Organisation for the Advancement of Structured Information Standards consortium (Oasis) has ratified version 2.0 of the Universal Description, Discovery and Integration web services specification, an important step towards finalising the widely awaited, significantly expanded 3.0 version of the standard.
Together with XML, Soap (Simple Object Access Protocol) and WSDL (Web Services Description Language), UDDI forms the foundation for the standards-based web services architecture many suppliers are endorsing as a way to link disparate data and applications.
Of the four standards, UDDI has been the most sparsely adopted. Security issues have held up wide implementation of the specification for publishing, locating and integrating with web services, but a number of suppliers backing UDDI said features planned for version 3 would help address those concerns.
"UDDI has the potential to do for server-to-server communication what DNS did for the internet, by making it much easier and cheaper to connect and stay connected to services," said Eugene Kuznetsov, chairman and chief technical officer of Oasis' UDDI technical committee member DataPower Technology.
Other committee members include Microsoft, IBM, SAP, Sun Microsystems, Oracle and Computer Associates International.
Committee co-chair Tom Bellwood, of IBM, forecast that UDDI use will pick up when version 3 features become available, such as support for digital signatures and multiregistry environments.
UDDI support is included in the latest version of IBM's WebSphere Application Server.
