Center node: "a domain specific transformation language"
  Abstract: Domain specific languages (DSLs) allow domain experts to model parts of the system under development in a problem-oriented no- tation that is well-known in the respective domain. The introduction of a DSL is often accompanied the desire to transform its instances. Although the modeling language is domain specific, the transformation language used to describe modifications, such as model evolution or refactoring operations, on the underlying model, usually is a rather domain inde- pendent language nowadays. Most transformation languages use a generic notation of model patterns that is closely related to typed and attributed graphs or to object di- agrams (the abstract syntax). A notation that reflects the transformed elements of the original DSL in its own concrete syntax would be strongly preferable, because it would be more comprehensible and easier to learn for domain experts. In this paper we present a transformation language that reuses the concrete syntax of a textual modeling language for hier-
