WSDL can describe network services (Web Services)

WSDL refers to the Network Services description language.

WSDL is a document written in XML. This kind of document can describe a Web service. It can specify the location of the service and the operations (or methods) provided by the service.

The Development History of WSDL in W3C

In March 2001, WSDL 1.1 was submitted by IBM and Microsoft as a W3C record (W3C note) to the W3C XML activity on the XML protocol to describe network services.

(W3C records are for discussion only. The publication of a W3C record does not mean that it has been approved by the W3C or the W3C team or any W3C member. )

In July 2002, the W3C released the first working draft of WSDL 1.2.

Please read more about the status and timeline of the specification in our W3C tutorial.
