Defining Model Transformations for Business Process Models Graphically

Because of today’s diversity of models and heterogeneous modelling languages in the area of business modelling there is a need to automate model transformations on the level of business process models. To define such transformation processes in a simple way, a graphical modelling approach is required. In previous works a textual model transformation tool, the BMT (BOC Model Transformer) has been introduced. It enables the transformation of business process models which are instances of different meta models. A rule file which contains XML-coded instructions controls the transformation process. To simplify the requirements for creating such a rule file this paper introduces a graphical approach for modelling transformation processes. For this purpose a meta model for the transformation language of the BMT is introduced. Furthermore transformation processes which represent model instances of this meta model are illustrated and discussed.
