An announcement from the Universal Description, Discovery, and Integration (UDDI) Project describes the publication of the UDDI Specification Version 2. The project is creating a "platform-independent, open framework for describing services, discovering businesses, and integrating business services using the Internet, as well as an operational registry that is available today." The Version 2 specification "delivers upon the roadmap and requirements outlined at the launch of UDDI in September 2000. New Features and improvements in the UDDI V2 specification will enable: (1) Description of Complex Organizations: Businesses can now describe and publish their organizational structure, including their business units, departments, divisions, and subsidiaries. (2) Improved support for internationalization: Businesses now have more flexibility in describing their business and services in multiple languages. (3) 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. (4) Richer searching options: Businesses can now search the registry using more expressive query parameters, using more fields and complex combinations of fields. The UDDI Community is comprised of more than 280 business and technology leaders working together to enable companies to quickly, easily, and dynamically find, and transact with one another." UDDI version 2 specification documents include the UDDI Data Structure Reference, UDDI XML Schema, UDDI Programmer's API, UDDI Replication Specification (with XML schema), UDDI XML Custody schema, and the UDDI Operators Specification.

UDDI Data Structure Reference Version 2.0. "This document outlines the details of each of the XML structures associated with these messages. The UDDI Programmers API Specification defines approximately 30 SOAP messages that are used to perform inquiry and publishing functions against any UDDI compliant service registry. Also see the UDDI XML schema."

UDDI Programmer's API Specification Version 2.0. "This document describes the programming interface that is exposed by all instances of the Universal Description, Discovery & Integration (UDDI) registry."
