WSDL - Subset

Subset WSDL

Subset WSDL (SWSDL)^[4] is a WSDL with the subset operations of an original WSDL. A developer can use Subset WSDL (SWSDL) to access Subset Service thus handle subset of web service code. SWSDL (SWSDL) can be used to perform web service testing and top down development. Slice the Web service based on Subset WSDL (SWSDL) to access Subset Service. Subset Service can be categorized into layers. SWSDLs are used for Web service analysis, testing and top down development. AWSCM^[5] is the pioneer tool to construct SWSDL's successfully.
