From wikipedia:
The Web Services Description Language
(WSDL, pronounced ‘wiz-dəl’) is an
XML-based language that provides a
model for describing Web services.
But in most cases, I found that WSDL is used in conjunction with SOAP. but as far as I know, if the WSDL is a language to describe web services. there should be possible to describe another kind of web services different from SOAP. is this possible? any examples?
Thanks!
WSDL 1.1 is for SOAP only, where WSDL 2.0 can be used for REST as well. Additionally there is a similar description language for REST based web services called WADL.
Neither WSDL 2.0 nor WADL are yet widely used.
