Automating the Maintenance of Non-functional System Properties using Demonstration-based Model Transformation

Given a base model with functional components, maintaining the non-functional properties that crosscut the base model has become an essential modeling task when using DSMLs. We present a demonstration-based approach to automate the maintenance of non-functional properties in DSMLs [29] . Instead of writing model transformation rules explicitly, users demonstrate how to apply the non-functional properties by directly editing the concrete model instances and simulating a single case of the maintenance process. An inference engine generates generic model transformation patterns, which can be refined by users and then reused to automate the same evolution and maintenance task in other models. Our demonstration-based approach has been applied to several scenarios, such as auto-scaling and model layout.
