Abstract : Nowadays, thanks to new tools and devices, students have more possibility to learn in a mobile way. Hence, e-learning platforms should support user mobility by offering access points to mobile devices. The system must adapt information corresponding to a learning activity to device's capabilities. Documents are provided in accordance to activities performed. For the coordination of activities we designed a flexible work-flow system named Cooperative Open Workflow. In this paper, we present our architecture which aims to support work coordination and user mobility.
