Markus, Arno, Bernd an me (Sven) have written an article about MDSD and oAW which has been published on The ServerSide today. It is called The Pragmatic Code Generator Programmer and is about a reimplementation of an exerceise from the best selling book "The Pragmatic Programmer" by Dave Thomas and Andy Hunt. We've used openArchitectureWare 4.1 and Xtext for the reimplementation, of course.
