In replying to your email I've just done a bit of browsing to learn about the difference between XText and XTend. The hello world video at [1] on XTend is useful, as is the page on the XTend syntax at [2]. For the Isis DSL I'd be looking for a similar degree of interoperability with Java, but going beyond what XTend does, especially with regard to its @Property annotation. A bit more googling led me to the "domain model" example for XText [3], and some pages showing how to extend this [4,5,6]. This looks like the obvious way to go, to me. > > 3. made myself somewhat familiar with the ecore architecture. > > Can you explain how this relates back to XTend?

Having not used XText myself, it'll be hard to judge whether this is a very easy project, or a difficult one. But in case of the former, it'd be good for the proposal to have some additional optional elements. I did in fact start (though never really complete) some Eclipse views; the code is all up on github [7]. You can see there's a bunch of views that it provides.

I'm happy to review it. I'll ask if Maurizio (who has some language experience) will lend a hand reviewing it too).
