Model driven development is a popular approach to master the complexity of computer based systems, but it is still missing well-established technologies for model transformations. A lot of research has been done to address this subject, most of it tends towards highly expressive and highly specialized transformation languages. This paper takes a contra point to this trend, proposing the transformation implementation language Mopa (Model Pattern), which is less expressive but provides more flexibility. Mopa is independent of the chosen modelling techniques, it allows the realization of different transformation approaches, and it is integrated into the Java programming language, hence easy to integrate into existing environments. Mopa is described with formal syntax and semantics, and this paper shows how to use Mopa to implement different existing transformation approaches.
