A tModel dscribes a "technical model" representing a reusable concept, such as a Web service type, a protocol used by Web services, or a category system. A tModel is used in UDDI to represent unique concepts or constructs. They provide a structure that allows reuse and, thus, standardization within a software framework. The UDDI information model is based on this notion of shared specifications and uses tModels to engender this behaviour. For this reason, tModels exist outside the parent-child containment relationships between the businessEntity, businessService and bindingTemplate structures.

a data structure representing a service type (a generic representation of a registered service) in the UDDI (Universal Description, Discovery, and Integration) registry

a technical specification that enables a client to determine if the Web service complies with a particular behavior or programming interface
