Heterogeneous megamodel slicing for model evolution

Slicing is a widely used technique for supporting comprehen- sion and assessing change impact during software evolution activities. While there has been substantial research into the slicing of particular model types, model-based software development typically involves heterogeneous collections of related models and there is little work addressing slicing in this context. In this paper, we propose a generic slicing ap- proach for"megamodels" -A well-known model management technique for representing and manipulating collections of models and relationships between them. Our approach ex- ploits existing model slicers for particular model types as well as the traceability relationships between models to ad- dress the broader heterogeneous model slicing problem. We illustrate our approach on an example of evolution in model- based automotive software development.
