@ritch If I understand your intentions correctly, we will use `type` property in remoting metadata, and then convert it to `responseModel` property in https://github.com/strongloop/loopback-explorer/pull/52. That way the strong-remoting part is not tied to Swagger, the DSL stays consistent, and we can support both Swagger 1.2 and 2.0 in the future.

If that's the case, then +1000.
