Web Services Description Language (WSDL)
WSDL is the Web Services Description Language. It describes where the Web service is
located, what it can do, and how these services can be invoked. The operations and messages
are described abstractly, and then bound to a concrete network protocol and message format to
define an endpoint. Related concrete endpoints are combined into abstract endpoints. WSDL
defines services as a collection of network endpoints (ports) (World Wide Web Consortium,
2004).
