Second version of UDDI standard published

The companies driving the UDDI project have unveiled version two of the proposed business registry specification, which includes a number of significant enhancements.

The companies driving the Universal Description, Discovery and Integration (UDDI) project have unveiled version two of the proposed business registry specification, which includes a number of significant enhancements.

UDDIv2 is based on comments submitted by the more than 280 companies involved in the UDDI community and comes just a month after Microsoft, one of the three UDDI registrars, launched the first Web services business registry based on the UDDI roadmap set out in September.

Among the new features, UDDIv2 includes support for complex organizations, improved internationalization, additional categorization and identifier schemes and richer search capabilities.

UDDI is seen by its proponents as a cornerstone for the emerging Web services infrastructure, and is intended to provide an open standard for the publishing and discovering of Web services via the Internet. Web services themselves are designed to simplify the process of conducting dynamic business-to-business e-commerce by using standardized components.

Initially, Microsoft, IBM and Ariba planned to operate as UDDI registrars, but Ariba subsequently stepped back to focus on its own financial problems and has been replaced by Hewlett-Packard, which will launch a registry based on UDDIv2 later this year.

Widespread use of UDDI isn't likely to take off until facilities for accessing it start to be built into core Web technologies. Nevertheless, the UDDI community is gathering this week in Atlanta to discuss requirements for the next version of the UDDI Specification (V3).

In the meantime, the enhanced UDDIv2 specification will enable businesses to describe and publish their organizational structure, including their business units, departments, divisions and subsidiaries.

Companies will also have more flexibility in describing their businesses and services in multiple languages, and they will be able to use additional industry-specific categories and identifiers to describe their businesses. Those searching the registry will be able to use more expressive query parameters, using more fields and complex combinations of fields.
