Development of Modelling Frameworks and Viewpoints with Kitalpha

A common need in system, software, and hardware engineering is to describe system architectures, especially in demanding domains such as aeronautics, defence or telecommunications. Kitalpha is an environment to develop and execute MBE (Model-Based Engineering) workbenches for description of system architecture. Kitalpha uses the DSL technique in order to develop such devel-opment environments accurately, quickly, and safely. This paper presents the main features of Kitalpha and lessons learned from a DSL-based development.
