Reconciliating divergent data is an important issue in concurrent engineering, mobile computing and software configuration management. Currently, a lot of synchronizers or merge tools perform reconciliations. However, they do not define what is the correctness of their synchronisation. In this paper, we propose to use a transformational approach as the(More)
Awareness widgets facilitate coordination for both synchronous and asynchronous groupware systems. Unfortunately, they cannot be used for multi-synchronous groupware systems. With a group of architects, we have designed a new awareness widget for multisynchronous groupware system called “State Treemap”. We have developed and integrated this widget in a(More)

In the context of cooperative work, a team alternates divergence phases where each member works in insulation on copies of objects and convergence phases during which the group reconciles and validates data. To support this style of working, we propose the concept of SAMS environments. A SAMS environment allows team members to work in Synchronous,(More)
Synchronisation of replicated shared data is a key issue in collaborative writing systems. Most existing synchronization tools are specific to a particular type of shared data, i.e. text files, calendars, XML files. Therefore, users must use different tools to maintain their different copies up-to-date. In this paper we propose a generic synchronization(More)
Semantic wikis have opened an interesting way to mix Web 2.0 advantages with the Semantic Web approach. However, compared to other collaborative tools, wikis do not support all collaborative editing mode such as offline work or multi-synchronous editing. The lack of multi-synchronous supports in wikis is a problematic, especially, when working with semantic(More)
Web 2.0 tools are currently evolving to embrace semantic web technologies. Blogs, CMS, Wikis, social networks and real-time notifications, integrate ways to provide semantic annotations and therefore contribute to the linked data and more generally to the semantic web vision. This evolution generates a lot of semantic datasets of different qualities,(More)
|Due to the popularization of Internet, cooperative applications are expected to become commonplace on the WEB. We are especially interested in cooperation in temporarily virtual enterprises. This paper introduces a new operator, called coo, which contributes to a better organization of the interactions between cooperating activities than current work ow(More)
