What is WSDL, UDDI and when do I need them?
Web Services that are available can be “Discovered”, information about the available Web service can be obtained from a “registry”, the standard for the Web Service registry function is UDDI (Universal Description, Discovery and Integration), and the standard for describing web services within the registry is WSDL (Web Service Description Language). WSDL and UDDI provide the equivalent of a tailor-made directory service for the dynamic discovery of web services, such dynamic discovery may be required to provide particular services to end users. Initial deployments of Web services may be implemented with static configurations and consequently will not require Web Service discovery standards.
