Graphical and Textual Models Embedded in a Constructor-Driven Transformation

In this paper, we describe a method to transform a model from a graphical representation into a textual representation and back. In order to do this, we take a context-specific modeling language approach. This approach is graph-based and data-flow driven. This language has a BNF (Backus-Naur form) for the textual representation and another BNF, which is able to generate a graphical representation of a model. We transform our example in a central step into an Abstract Data Type (ADT) driven specification with an abstract syntax. After that we transform it to the appropriate and semantically transferable target form.
