WSDL for other protocols different than SOAP?

Question

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!

Answer 1

You can use WSDL 2.0 to describe a REST web service.

There exist binding for CORBA as well.

Answer 2

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.
