<
architecture> (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.
