In this paper, the work on a visual specification language for high-level design of concurrent systems with heterogeneous coordination models, called Visual Coordination Diagrams (VCD), is presented. Special emphasis is given to component-based specification of heterogeneous systems. The key property of VCD is separation of behavioral aspects from coordination aspects.
We briefly summarize recent research related to the topic and give an overview of VCD language and its semantics. The summary of already achieved results of our work is presented as well.
