Towards Combinators for Bidirectional Model Transformations in Scala

In model-driven engineering (MDE), often models that conform to different metamodels have to be synchronized. Manually implemented model synchronizations that are not simple bijections are hard to maintain and to reason about. Special languages for expressing bidirectional transformations can help in this respect, but existing non-bijective languages are often hard to integrate with other MDE technologies or depend on up-to-date tool support. We embed lenses – a promising term-rewriting-based approach to bidirectional transformations – into the Scala programming language and use lenses for model synchronization. We discuss how this allows for static type-safety and for seamless integration with existing Java-based MDE technologies.
