OASIS has approved UDDI version 2 as an OASIS Open Standard. UDDI (Universal Description, Discovery and Integration) specifies a standard interoperable platform that enables companies and applications to find and use Web services over the Internet. UDDI V2 components include the UDDI Version 2 API Specification, Data Structure, XML Schema, Replication Specification, XML Replication Schema, XML Custody Schema, Operator's Specification, WSDL Service Interface Descriptions, and UDDI tModels. The OASIS UDDI Specification Technical Committee, part of the UDDI.org OASIS Member Section, was been chartered "to continue work on the Web services registry foundations developed and published by UDDI.org. The UDDI specifications form the necessary technical foundation for publication and discovery of Web services implementations both within and between enterprises. The scope of the UDDI Technical Committee is the support of Web services discovery mechanisms in the following areas: (1) Specifications for Web services registries and Web service interfaces to the registries; (2) Replication or synchronization mechanisms across multiple implementations; (3) Security facilities for access or manipulation of the registry and maintaining data integrity. The UDDI specifications will use implementation and language neutral XML formats defined in XML Schema where appropriate."
From the Announcement
The OASIS interoperability consortium today announced that its members have approved the Universal Description, Discovery and Integration specification (UDDI) version 2.0 as an OASIS Open Standard, a status that signifies the highest level of ratification. UDDI enables companies and applications to dynamically publish, locate, and use Web services.
Uttam Narsu, Vice President, Forrester Research, Inc. noted, "While UDDI has not been as widely adopted as SOAP and WSDL, UDDI v2, under the aegis of OASIS, offers a concrete step to the widely anticipated version 3 specification. We forsee UDDI adoption as critical to the realization of a service-oriented architecture, and expect to see a significant increase in its adoption over the next two years."
"We came to OASIS with the goal of advancing UDDI into a recognized industry standard with support and input from the broadest possible range of constituents," recalled Luc Clement of Microsoft, co-chair of the OASIS UDDI Specification Technical Committee. "UDDI's ratification as an OASIS Open Standard indicates our success in establishing an interoperable, cross-industry standard that provides a cornerstone for the Web services architecture."
Members of the OASIS UDDI Specification Technical Committee include Computer Associates, Fujitsu, IBM, IONA, Microsoft, Novell, OpenNetwork, Oracle, SAP, SeeBeyond, Sun Microsystems, Tata Consultancy Services, and others.
According to Tom Bellwood of IBM, co-chair of the OASIS UDDI Specification Technical Committee, "UDDI v2 is being widely implemented today. It provides powerful features like business relationships and external taxonomy validation. As OASIS now continues moving version 3 towards a standard, with its support of multi-registry environments and digital signature features, we expect the use of UDDI in all environments to expand even further."
Before becoming an OASIS Open Standard, UDDI v2 first completed an extensive public review and was approved by the OASIS UDDI Specification Technical Committee. Then, the specification demonstrated its readiness through multiple implementations, after which UDDI was reviewed and approved by the OASIS membership as a whole.
"Universal Description, Discovery and Integration, or UDDI, is the name of a group of web-based registries that expose information about a business or other entity and its technical interfaces (or APIs). These registries are run by multiple Operator Sites, and can be used by anyone who wants to make information available about one or more businesses or entities, as well as anyone that wants to find that information. There is no charge for using the basic services of these operator sites."
"By accessing any of the public UDDI Operator Sites, anyone can search for information about web services that are made available by or on behalf of a business. The benefit of having access to this information is to provide a mechanism that allows others to discover what technical programming interfaces are provided for interacting with a business for such purposes as electronic commerce, etc. The benefit to the individual business is increased exposure in an electronic commerce enabled world."
"The information that a business can register includes several kinds of simple data that help others determine the answers to the questions 'who, what, where and how'. Simple information about a business -- information such as name, business identifiers (D&B D-U-N-S Number, etc.), and contact information answers the question 'Who?' 'What?' involves classification information that includes industry codes and product classifications, as well as descriptive information about the services that the business makes available. Answering the question 'Where?' involves registering information about the URL or email address (or other address) through which each type of service is accessed. Finally, the question 'How?' is answered by registering references to information about interfaces and other properties of a given service. These service properties describe how a particular software package or technical interface functions. These references are called tModels in the UDDI documentation."

PDF - http://uddi.org/pubs/ProgrammersAPI-V2.04-Published-20020719.pdf
"This document describes the programming interface and expected behaviors of all instances of the Universal Description, Discovery and Integration (UDDI) registry. The primary audience for this document is programmers who want to write software that will directly interact with a UDDI Operator Site. Private implementations of the UDDI specification should provide support for the interface described here as well as the behaviors defined... coupled with the UDDI API schema (uddiAPI2.xsd) and the information in the UDDI Version 2.0 Data Structure Reference, this document defines a programming interface that is available according to the licensing terms defined in the beginning of this document. Software developers, businesses and others are encouraged to define products and tools that make use of both public and private UDDI registries. Developers who license this specification are further encouraged to build registries that are compatible with the UDDI specifications..."

PDF - http://uddi.org/pubs/DataStructure-V2.03-Published-20020719.pdf
"The programmatic interface provided for interacting with systems that follow the Universal Description Discovery & Integration (UDDI) specifications make use of Extensible Markup Language (XML) and a related technology called Simple Object Access Protocol (SOAP), which is a specification for using XML in simple message based exchanges. The UDDI Version 2.0 API Specification defines approximately 40 SOAP messages that are used to perform inquiry and publishing functions against any UDDI compliant service registry. This document outlines the details of each of the XML structures associated with these messages..."

PDF - http://uddi.org/pubs/Replication-V2.03-Published-20020719.pdf
"This document describes the data replication process and programmatic interface required to achieve complete data replication between UDDI Operators. The replication process makes use of Extensible Markup Language (XML) and a related technology called Simple Object Access Protocol (SOAP). SOAP is a specification for using XML in simple message-based exchanges. The UDDI Version 2.0 Programmer's Reference Specification provides a short introduction to the project and describes the public UDDI interfaces. This specification describes the interfaces required to perform all of the UDDI Operator to UDDI Operator communications... Implementers will find information in this document that defines the required replication process protocol and recommended and required behaviors all UDDI Node Operators must implement as a part of their UDDI Services. The goal of these policies and behaviors is to ensure that the UDDI Service works smoothly, both for the user community as a whole, and for the individual operators..."

The replication specifications describe the protocol used for UDDI Operator Nodes to synchronize registry information. This document describes the behavior and operational parameters required of all UDDI Node Operators... Implementers will find information in this document that defines one required protocol (Custody Transfer), as well as recommendations and the operational behaviors all UDDI Node Operators are required to implement as a part of their UDDI services.
