This allows humans and UDDI/WSDL aware tools to locate the service interface definition. The Binding Template. UDDI4r − It provides a basic UDDI client for inquiry and publishing. PIP2A2 − Enables a partner to query another for product information. • The UDDI Data Model. The UDDI registry can replicate data according to multiple replication definitions that are defined using UDDI standard queries. WSDL is represented in UDDI using a combination of businessService, bindingTemplate, and tModel information. However, the UDDI data model is only capable of storing one layer of annotations because it was designed to deal with flat identification and categorization systems. tModel is a way of describing the various business, service, and template structures stored within the UDDI registry. Retrieving Information. delete_binding − Removes the given web services technical details from the UDDI registry.
