We have had two workshops on model-driven architecture and development at the HDM. You can find the latest workshop and some reflections on the results here: MDA/MDSD Uses and alternative approaches. At HDM I've organized generative computing around three different lectures:

Right now it seems as if Markus Voelter and Jorn Bettin provide useful papers on patterns for MDSD, development processes based on generative technologies and so on. Also the community around the former b+m generator seems quite active.
