The UDDI specification The UDDI specification and protocol is a cross-industry effort, driven by the OASIS consortium, that takes advantage of W3C and IETF10standard message definitions, application programming interfaces (APIs) and data structures to build distributed registries on the web. UDDI includes a specific definition of the hierarchical relationship between a single instance of a UDDI implementation and others to which it is related. These data types are defined in several XML schemas, which together form a base information model and interaction framework of UDDI registries. The UDDI specification defines core data types that include a description of the service's business function, information about the service's publisher, the service's technical details and API, and other metadata. Universal Description, Discovery, and Integration (UDDI) provides the definition of a set of services supporting the description and discovery of (1) businesses, organizations, and other Web Services providers, (2) the Web Services they make available, and (3) the technical interfaces which may be used to access those services.

UDDI is seen with SOAP and WSDL as one of the three foundation standards of web … An operator site implements the UDDI specification and allows users to publish their own Web Service information for increased exposure and query the site for others' Web Service information. The Schema Centric Canonicalization algorithm addresses these concerns. 3. Using these models, or generic categories, a UDDI registry user can search for a type of service, rather than needing to know the access details for a specific service. The J2EE Engine provides a tool that fully implements the Universal Description Discovery and Integration (UDDI) functions based on the UDDI v2.0 specification. Existing XML Canonicalization algorithms such as Canonical XML and Exclusive XML Canonicalization suffer from several limitations and design artifacts (enumerated herein) which significantly limit their utility in many XML applications, particularly those which validate and process XML data according to the rules of and flexibilities afforded by XML Schema.
