A role language to interpret multi-formalism System of systems models

New systems are by nature distributed and built around existing systems. The concept of System of systems (SoS) has become the key for creating new systems. Modeling is a central issue of SoS design and evolution. Since subsystems of a SoS can be modeled in different languages, the SoS modeling environment should be able to handle heterogeneous modeling formalism. Traditionally, this problem is handled through type-based model transformations which are rigid and static. In this paper we address this problem by proposing a role modeling language offering a dynamic and extensible way to interpret and connect models from different languages. An usage of the role modeling language on a seafloor observatory use case is shown.
