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.

In the automotive industry, the model driven development of software, today considered as the standard paradigm, is generally based on the use of the tool MATLAB Simulink/Stateflow. To increase the quality, the reliability, and the efficiency of the models and the generated code, checking and elimination of detected guideline violations defined in huge catalogues has become an essential task in the development process. It represents such a tremendous amount of boring work that it must necessarily be automated. In the past we have shown that graph transformation tools like Fujaba/MOFLON allow for the specification of single modeling guidelines on a very high level of abstraction and that guideline checking tools can be generated from these specifications easily. Unfortunately, graph transformation languages do not offer appropriate concepts for reuse of specification fragments - a MUST, when we deal with hundreds of guidelines. As a consequence we present an extension of MOFLON that supports the definition of generic rewrite rules and combines them with the reflective programming mechanisms of Java and the model repository interface standard JMI.

As an increasing number of industrial software development projects adopt model-driven development technologies, there is an emerging need for analysis, transformation, and integration of models. In this paper, we propose MOSL, an integrated specification language composed of MOF 2.0, OCL 2.0, Fujaba SDM, and Triple Graph Grammars as a suitable metamodeling and specification language. This language is the basis of the MOFLON metamodeling framework, which is currently developed at our department.
