Model-Driven Architecture,including model-drivenapproaches in general,holds the big promise of moving software development towards a higher level of - straction. Given the challenges in the software industry of delivering more c- plex functionality with less e?ort, I am convinced that it isn’t a question of whether model-driven development will succeed, but rather a question of when it will break through. However, before this can happen, we have many challe- ing problems to conquer. There are both theoretical and pragmatic problems to solve and therefore we need a close collaboration between industry and the academic world. ThegoaloftheEuropeanConferenceonModel-DrivenArchitecture-Fo- dations and Applications (ECMDA-FA) is to bring together industry and academia to tackle the problems in model-driven development. This volume includes 18 foundation papers and 12 application papers, which is a ?ne b- ance between both worlds. ECMDA-FA 2006 also hosted six workshops on both theoretical and practical aspects of MDA. Furthermore, the keynote speakers, David Frankel and Bran Selic, from some of the world’s largest IT companies proved that industry is very much involved in MDA.
