What is the prefered method for a 'WSDL' for REST webservice?

Question

I have build plenty of SOAP webservices, but am building a REST webservice for a specific project, and I was wondering what people used for a \'WSDL\' for REST services or if it

Answer 1

While Sam's correct that RESTful web applications don't need a direct analog to WSDL, there is an XML vocabulary that's useful for describing RESTful web apps: WADL, or Web Application Description Language. At my company we primarily use WADL to define a spec for a given service that we want to build - we don't generally use it programmatically. That said, the WADL home page includes some Java tools for code generation, and Restlet, the Java REST framework, includes a WADL extension for dynamically wiring applications based on WADL and dynamically generating WADL based on a wired application. I'm a fan of WADL, and recommend that you check it out.
