If I understand well, is it a Model-Driven Development (MDD) framework? If yes it's quite nice to see some people are working on that.

The only famous tool I heard about it was some MOF Plugin on Eclipse IDE. And at a different level but kind of the same philosophy, Jetbrain MPS (but more focus on the DSL part).

I am not sure yet if I adhere with MDD principles, but at least it's good to see a modern tool to try it out.
