With the explosion in online business transactions and B2B (business-to-business) transactions, companies doing business on the Web need an easy way to discover one another and publish information that can be used to set up transactions. UDDI (Universal Description, Discovery, and Integration) is a standard that defines a common way for organizations to publish information about business services and provide other organizations with information that can be used to integrate business processes. UDDI is more than a directory. The UDDI Business Registry is an implementation of the UDDI specification in which organizations publicly list descriptions of services and methods of engagement. The UDDI specifications take advantage of Internet standards developed by the W3C and the IETF, including HTTP, DNS, XML, and SOAP. SOAP is a messaging specification originally developed by Microsoft but now promoted by the W3C.
