Service de réconciliation pour la synchronisation de copies

The concept of multi-synchronous interaction has become popular in the context of collaborative work [7]. This cooperation mode allows the participants of a virtual team to alternate periods of work in coupled mode collaborating with the other team members with isolated work in uncoupled mode. As divergence may then occur, a reconciliation mechanism is required for team members to synchronize their work. This article deals with collaborative work among mobile users who manipulate component-based applications. We present the architecture of a reconciliation service that can be seen as an extra-fonctional service supported by the components container. More precisely we propose to extend a component-based middleware by the integration of a synchronisation service implementing the SOCT4. ("Sérialisation des opérations concurrentes par transposition") algorithm [23, 24] based on operation transforms technology.
