UDDI Specification Version 2

UDDI Project Releases Second Version of the UDDI Specification

Key Element of Emerging Web Services Infrastructure Continues Maturation Through Community Feedback

New York, NY, USA. June 18, 2001.

The Universal Description, Discovery, and Integration (UDDI) project today announced the public availability of the second version (V2) of the UDDI Specification.

Version 2 delivers upon the roadmap and requirements outlined at the launch of UDDI in September 2000. It encompasses input on key features from the entire UDDI Community, such as support for complex organizations, improved internationalization, additional categorization and identifier schemes, and richer search capabilities. The specification is available for download at

"UDDI is a core component of the emerging web services infrastructure," stated Daryl Plummer, Group Vice President, Internet and E-Business Technologies, Gartner Group. "Version 2 of the UDDI specification delivers a number of important features that will facilitate business-to-business ecommerce."

Continuing the momentum, the UDDI Community is gathering this week in Atlanta, GA, to discuss requirements for the next version of the UDDI Specification (V3).

New Features and Improvements

The key new features in the UDDI V2 specification will enable:

  • Description of Complex Organizations. Businesses can now describe and publish their organizational structure, including their business units, departments, divisions, and subsidiaries.

  • Improved support for internationalization. Businesses now have more flexibility in describing their business and services in multiple languages.

  • Additional categorization and identifier schemes. Businesses can use additional industry specific categories and identifiers to describe their businesses. For example, a chemical company may now use existing industry specific categories to describe themselves and their services. These categories can be validated during registration through third parties such as a chemical industry association.

  • Richer searching options. Businesses can now search the registry using more expressive query parameters, using more fields and complex combinations of fields.
