Real-time model-driven engineering: an overview

After a maturing period of over a decade, Model-Driven Engineering (Mde) starts to extend to novel areas that include safetycritical or embedded, but also cyberphysical systems. These domains explicitly manipulate time. This paper proposes three dimensions to analyse how Mde frameworks integrate time: which transformation paradigm is used, how time is represented inside it, and which characteristics of time are considered. Without claiming for exhaustivity, we validate our approach by analysis several contributions from the literature, thus offering an overview of the current practice in Real-Time Mde.
