The paper deals with the design and a prototype implementation of a collaborative repository of scientific learning objects based on an efficient mechanism of filing and retrieving distributed knowledge on the Grid. The proposed repository can deal with a large variety of different learning contents. Its prototype implementation, developed for Chemistry contents, is part of an extended architecture consisting of a federation of autonomous local repositories. The federation is led by a coordinator who keeps track of the repository in which the learning objects are directly stored or referenced. In each repository server, a locally hosted Web Portal allows a easy management of the repository through a CMS front-end.
