Nowadays, a typical software development process involves many developers which participate in the development process by using a wide variety of development tools. As a consequence, the data representing the project as a whole is distributed over different development tools. For the purpose of consistency, maintainability, and traceability it is an essential task to be aware of the relationships between semantic equivalent data in different tool repositories. The real-time systems Lab at the Technische Universitat Darmstadt performs research in the area of tool and metamodel integration to provide solutions to overcome this gap. In this demonstration we present the metamodeling framework MOFLON that addresses these issues by bringing together the latest OMG standards with graph transformations and triple graph grammars. Using MOFLON, developers can generate code for specific tools needed to perform analysis and transformation on one development tool or to incrementally integrate data of different modeling tools.

Current rule-based model transformation approaches as the Query / View / Transformation (QVT) standard or Triple Graph Grammars (TGGs) disregard means for structuring model transformation specifications. As a result large scale model transformation specifications are hard to understand and to maintain. Furthermore, these specifications cannot utilize reusing mechanisms which would reduce the size of the specifications and improve their readability. In this paper we discuss how to transfer means for structuring huge metamodels and models as provided by common modeling languages to the world of model transformation languages. We focus on generalization issues as well as on package dependencies. As a result we come up with an extension to our TGG approach that enables the user to specify structured bidirectional model transformations in a declarative way.
