Viewpoints in the Smart Home Product Line

In product lines for systems engineering a number of different viewpoints on the modeled system have to maintained, comprising both software-related viewpoints and domain-specific views on hardware and environment. A major engineering challenge is to maintain model transformations and code generators working on these viewpoints. This paper proposes an engineering approach that explicitly describes the relation between viewpoints. We use these descriptions to better modularize transformations and thus improve the maintainability of MDD tool chains. This is shown within a smart home case study, which combines building automation and software engineering.
