What is the purpose of a WSDL to UDDI mapping model? Solution the purpose of the mapping is : The web services description language is an extensible Markup language , which describes the web services that represented as group of web endpoints that perform functions on messages. A wsdl provides the description for the services that includes definitions as the abstract model which provides group of actions on the messages and also the concrete set of protocols that binds the operations with the messages an d the binding contains specification for the network endpoints. Universal Description Discovery and Integration (UDDI) describes the set of methods for publishing and discovering detailed information as the description for the services. By using UDDI it is possible for the entities that are required to describe business information as well as the service information. Usually the WSDL contains the description about the data that is defined in the group of services as the complementary for the data identified in the UDDI archive . Many different kinds of descriptions of services are supported by the UDDI . .
