Abstract : We present the integration of the Behavioral Coordination Operator Language (B-COOL) into the GEMOC Studio. B-COOL enables the system designer to automate the coordination of models by specifying Operators between Domain-Specific Modeling Languages. In this demonstration, we present how B-COOL is used to coordinate the heterogeneous model of a video surveillance system. To this propose, we define operators between timed finite state machines and activity diagrams. These operators are used to generate an explicit model of coordination that can be executed and verified. This demonstration comes as a support for the paper accepted into the main conference.
