A Generative Approach to Model Interpreter Evolution

Domain-specific modeling techniques are being adopted with more frequency in the engineering of computer based systems. In the presence of new stakeholder requirements, it is possible that a meta-model undergoes numerous changes during periods of evolution. There is a fundamental problem in maintaining the model interpreters in terms of such metamodel schema changes. This position paper outlines the technical challenges involved in providing evolution of model interpreters. The paper proposes an approach that is based on a mature program transformation engine to automate the evolution of interpreters in the presence of meta-schema changes.
