A multi-modal coordination service model for cooperative distributed systems engineering

This paper defines a coordination model allowing different collaboration modalities to be managed by maintaining consistency of the distributed management actions at the user and collaborative tool levels. The model was achieved to manage multi-tools and multi-user collaboration sessions during the DSE project for design review activities in space domain. We have identified and formalized three coordination relations that guarantee maintaining the consistency. Our model is used to implement a software component for collaborative session management. We proceed by control of user-level management actions and by automated execution of tool-level management actions.
