Randy,

I suspect any RESTful spec will need a little of both - some automatically generated content from the schema (to JSON, presumably) and text that "binds" it all together into a spec that can actually be implemented (model is abstract, binding is concrete).

Waving our hands while saying WSDL defines everything is, IMHO, a mistake.  All you have to do it look at IPP FaxOut or IPPSIX to see how a direct mapping of a Semantic Model/Cloud Imaging schema isn't enough on its own.

You don't have to know XML, XSD, or WSDL dialect to understand it.

We may need to review a couple of other "out-of-scope" items to make sure we're not specifying an abstract model that can't be instantiated by something "concrete" that actually works.

As Glen likes to call it, our focus will be on "device registration" and not on the specific security/ACL implementation details - that will be IDS's bailiwick.  Thus, it will be possible to use the model with any security framework so long as it meets the basic requirements of the Semantic Model and whatever we come up with for requirements of Cloud.
