In recent years the amount of educational resources available online has constantly increased. However, it remains challenging how to make use of such wealth of material in a simple and effective way, ranging from primary schools to high schools. Typically, the lack of available time and the peculiar procedures imposed by each system constitute the main difficulties faced by the teachers. In this context, this work proposes an architecture to allow different repository systems to work together in a transparent fashion by means of the CMIS API and through a new integration layer with a simplified interface, designed on the basis of the needs of typical content creators and users. The preliminary feedbacks are encouraging, showing that the platform could be widespread adopted by the Italian educational system.
