W3C WSDL activity

WSDL is an XML-based language that describes Web Services and how to access it.

Wsdl

WSDL (Web Services Description Language) is an XML format used to describe Web Services.

To learn more about WSDL, read our WSDL tutorial.

WSDL 1.1

As an XML format that describes Web Services, WSDL 1.1 was recommended to W3C (by Ariba, IBM, and Microsoft) in a march 2001 record.

This record also describes how to use WSDL in combination with SOAP 1.1, HTTP GET/POST, and MIME.

W3C WSDL 1.1 is only a record for discussion (NOTE). The publication of this record does not represent any degree of W3C's endorsement of it.

WSDL 1.2

The first draft work was published on 17 December 2001.

The latest draft work was released on June 11, 2003.

WSDL 2.0

W3C's XML Protocol team is currently working on WSDL 2.0.

Web structure

At the heart of the Web structure is a Web server, which is generally undertaken by a separate server, the database server is the information management system database server, each client data request is submitted by the Web server to the database server, and then the Web server returns to the client sent to the request.

The Web server here can be set up as a gateway, with one end of the information management system's intranet and the other end connected to the enterprise Intranet, which avoids direct external exposure to the intranet and makes the Web site accessible internally.
