It is almost impossible to distinguish and keep track of all the cooperative systems and computer-supported learning environments currently available. One of the key characteristics of any cooperative system is the chosen access rights model. Most systems of this sort employ a model that is specifically tailored to one application area, e.g. a number of fixed roles. This article begins by examining the different basic characteristics of access rights in the area of cooperative work, and then goes on to present an open and flexible rights model. In addition to covering classical access rights, this model enables rights to be delegated to others and inherited contextually. The presented model is implemented in the cooperative sTeam open-source work environment. Finally we will present some evaluation results of using sTeam at various courses at our university.
