What Is WSDL?

WSDL (Web Services Description Language) is an XML-based interface definition language that is used for describing the functionality offered by a web service.

WSDL 2.0 uses the following XML elements:

• Service - Contains a set of system functions that have been exposed to the Web-based protocols.
• Endpoint - Defines the address or connection point to a Web service. It is typically represented by a simple HTTP URL string.
• Binding - Specifies the interface and defines the SOAP binding style (RPC/Document) and transport (SOAP Protocol). The binding section also defines the operations.
• Interface - Defines a Web service, the operations that can be performed, and the messages that are used to perform the operation.
• Operation - Defines the SOAP actions and the way the message is encoded, for example, "literal." An operation is like a method or function call in a traditional programming language.
• Types - Describes the data. The XML Schema language (also known as XSD) is used (inline or referenced) for this purpose.
