I've searched all over for an example of using a Common Lisp library (like Drakma) to call a RESTful web service, but all I've found are specific API calls to third party services. The Drakma site doesn't indicate how a schema would be used with an http service call.
If I have an schema/XSD and a URL for a RESTful web service that I'd like to invoke, is there a quick tutorial on how to get started calling the service, and what a response would look like?
Here are two things that you can try. The first is an course assignment for EECS 235 at Northwestern University that walks through using XML-RPC in Lisp. This links to library and gives examples of how to use it. The second is Allegro's Common Lisp API for SOAP.
