Atom protocol and WADL


Via The Aquarium I see that Mark Hadley's work on Web Application Description Language (WADL) is now a Sun Technical Report. WADL provides a way to describe a REST based web application or service so that tools can discover services, generate proxies, etc. As I understand it, WADL is to REST as WSDL is to SOAP.

There's also something new since the last time I looked at WADL. Mark has added a section on the Atom protocol and examples that show how to use a WADL file to replace an Atom introspection document. Looks like good stuff to me. If you need an introspection doc for your REST based web service, why not use WADL?

Via Google, I found that there's also a WADL presentation on-line.

WADL sounds interesting. The WADL presentation link is pointing to Aquarium now. Were you planning to link to http://weblogs.java.net/blog/mhadley/wadl.pdf ? --Siva.

Thanks for pointing that out. I corrected the presentation link.
