Since meta-modeling is non-constructive, it does not provide a systematic way to generate all possible meta model instances. In our approach, an instance-generating graph grammar is automatically created(More)
In this paper we present a model transformation from a visual representation (Vi-sualOCL) of the Object Constraint Language (OCL) to the textual one using graph transformation. Starting from VisualOCL diagrams, we show how their underlying abstract syntax can be modeled by typed attributed graphs and converted into an OCL string representation using graph(More)
