Web Service Definition Language


Web Service Definition Language

(architecture)(WSDL) An XML format for describing networkservices as a set of endpoints operating on messagescontaining either "document oriented" or "procedure oriented"information. The operations and messages are describedabstractly, and then bound to a concrete network protocol andmessage format to define an endpoint. Related concreteendpoints are combined into abstract endpoints(services).

WSDL is typically used with SOAP over HTTP but it isextensible to allow description of endpoints and theirmessages independent of what message formats or networkprotocols.
