This paper presents the work done by the research group of the Open University of Catalonia within the coordinated project towards the definition of adequate grid and peer-to-peer middleware for cooperative learning environments. The main results of our research consist in designing a layered framework for modelling online collaborative learning interactions which in turns leads to the development of a computational platform, called Collaborative Learning Purpose Library (CLPL), that can be used as a basis for the development of Collaborative Learning applications that achieve an efficient event (group activity) information management. To that end, we developed a Grid approach in order to increase the efficiency of processing event log files. Finally, we developed a middleware architecture, called LaCOLLA, that follows the peer-to-peer paradigm and can be used to build collaborative applications that provide general purpose collaborative functionalities while it pays special attention to the autonomy of its members and to self-organization of the components of the infrastructure. All these results were reflected in several publications in international journals, refereed conferences, as well as participations to new European projects.
