WSDL
Web Services Description Language (WSDL) is an XML-based interface and implementation description language. The service provider uses a WSDL document in order to specify:
| 
|
| The operations a Web service provides |
|
|
|
| The parameters and data types of these operations |
|
|
|
| The service access information |
WSDL is one way to make service interface and implementation information available in a service registry. A server can use a WSDL document to deploy a Web Service. A service requester can use a WSDL document to work out how to access a Web Service (or a tool can be used for this purpose).
The specification for WSDL is available at:
