       Web Services Description Language (WWW, XML)

WSDL

    (WSDL) An XML format for describing network
   services as a set of endpoints operating on messages
   containing either "document oriented" or "procedure oriented"
   information.  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
   (services).

   WSDL is typically used with SOAP over HTTP but it is
   extensible to allow description of endpoints and their
   messages independent of what message formats or network
   protocols.
