Abstract

We present a general approach to the incremental development of model-based applications using endogenous transformations, i.e. transformations whose input and output models conform to the same metamodel. Our work describes these transformations as model deltas that, when composed, deliver a complete model. We establish a relationship between a metamodel and its corresponding delta metamodel, show how model deltas can be defined as model changes (additions), explain how deltas can be composed using domain-specific composition algorithms, and propose metamodel annotations to specify these algorithms. We present different case studies as proofs of concept.
