Construction de collecticiels : étude d'architectures logicielles et de fonctions de contrôle

Abstract : The focus of this dissertation is the study of groupware or CSCW-applications development. One major approach for groupware development consist of constructing a platform that provide the different services required for supporting collaboration. In this work we start by out-lighting the main requirements for a CSCW platform. Then we describe and compare the different possible approaches for implementing these requirements. The results of the above mentioned study are used to feed the conception and the implementation of a new CSCW platform that we call : Colt (for Collaboration Terrain). Main features of the proposed platform are : 1) Easy transition between individual and collaborative work and 2) High functional and structural flexibility. Colt users share a common information space. Each has his own role that defines his view on the shared space. The flexibility of the environment allows the users to define a wide variety of collaborative activities and to dynamically adjust and reconfigure existing ones. A special attention is paid to provide the environment with various strategies for concurrency control. In this goal, an original protocol, called LICRA (for Lock-free Interactive Concurrency Resolution Algorithm) is integrated in the environment. LICRA implements an optimistic strategy based on the use of operation transformation mechanism. A first prototype of Colt, developed in TCL-TK, is now available for a Unix-platform.
