What is WSDL?

WSDL is the Web Service Description Language. It provides a formal description of a web service, much like CORBA's IDL. The WSDL file is all you need to know how to call the web service; toolkits can generate proxy code from a WSDL file directly. The official WSDL definition is at http://www.w3.org/TR/wsdl.
