Hi Steven, It depends what, though the answer is probably: not really.
Isis generates the user interface dynamically from a metamodel, but that metamodel is built by reflecting over domain object classes. There is no capability to build the metamodel from a different structure, such as a REST API. What you could do is to create a view model [1] for each REST representation that you want to surface in the UI, and optionally use actions on those view models (or mixin actions) to invoke PUT and POST operations on your backend REST API.
