hi,

Web service standards have made outstanding progress. However, let's take a quick step backwards to examine an older standard called Universal Description, Discovery and Integration of Web services (UDDI). The UDDI specification defines a SOAP-based Web service for locating Web services and programmable resources on a network. It offers a foundation for sharing information about internal services across the enterprise and public services on the Internet.

What is UDDI?

Windows Server 2003 includes Enterprise UDDI Services, a dynamic and flexible infrastructure for XML Web services. This standards-based solution enables companies to run their own UDDI (Universal Description, Discovery, and Integration) directory for intranet or extranet use, making it easier to discover Web services and other programmatic resources. Developers can easily and quickly find and reuse the Web services available within the organization. IT administrators can catalog and manage the programmable resources on their network. Enterprise UDDI Services also helps companies build and deploy smarter, more reliable applications.

How is UDDI Services designed?

UDDI Services is a managed code service in Windows Server 2003. It was developed using the Microsoft .NET Framework and utilizes Microsoft's experience running the Microsoft public node of the UDDI Business Registry. UDDI Services can be accessed through a Web-based user interface or programmatically through a SOAP interface.

UDDI Services automatically publishes its existence and location within UDDI Services so that it is easily discoverable as a Web service.

Hi Aman,

UDDI (Universal Description, Discovery, and Integration) currently represents the discovery layer within the Web services protocol stack.

UDDI was originally created by Microsoft, IBM, and Ariba, and represents a technical specification for publishing and finding businesses and Web services.
At its core, UDDI consists of two parts.

First, UDDI is a technical specification for building a distributed directory of businesses and Web services. Data is stored within a specific XML format, and the UDDI specification includes API details for searching existing data and publishing new data.

Second, the UDDI Business Registry is a fully operational implementation of the UDDI specification. Launched in May 2001 by Microsoft and IBM, the UDDI registry now enables anyone to search existing UDDI data. It also enables any company to register themselves and their services.

The data captured within UDDI is divided into three main categories:

White Pages: This includes general information about a specific company.

For example, business name, business description, and address.

Yellow Pages: This includes general classification data for either the company or the service offered.

For example, this data may include industry, product, or geographic codes based on standard taxonomies.

Green Pages: This includes technical information about a Web service. Generally, this includes a pointer to an external specification, and an address for invoking the Web service. You can view the Microsoft UDDI site, or the IBM UDDI site. The complete UDDI specification is available at uddi.org.

Beta versions of UDDI Version 2 are available at:

Hewlett Packard

IBM

Microsoft

SAP
