I believe so.  In addition to model structure, operations can also be supported using the "Category" mechanism (class associated with the factory, which contains static methods implementing the operation).  Here's the documentation (sparse as it is): http://code.google.com/p/google-web-toolkit/wiki/AutoBean

Just to clarify my original intent behind an API: I was only considering interfaces, not implementations.  Those interfaces would collect cruft as the API evolves.  This implies the interfaces would be backward compatible as long as desired.  Also, I believe that maintaining an interface would help keep developers "honest," highlighting the fact that management details are API (i.e. change the structure, roll the version and update the interface; I suppose that implies the version can be queried).  In the end, a client includes a JAR that defines the interfaces, implements those however they want (e.g. AutoBean framework, ModelNode, etc.) and they're off.  They don't need to maintain a parallel set of interfaces.  And, if they're using an older set of interfaces with a newer server version, they should still get the benefit of partial operability, as the implementations are ultimately working on the DMR structure (strings and whatnot).

Best,
