Abstract
Technology has increasingly permeated the educational context making the use of learning objects (LOs) very popular. LOs need to be stored and cataloged so they can be located and retrieved in an efficient manner by both students and teachers. Furthermore, the objects collected in different repositories must be examined individually in order to select which ones best match the user’s needs. The main goal of this work is to propose a model that, prepared to the Web 3.0, enables LO to be used, reused or adapted from heterogeneous environments. To reach this goal the creation of a LO federation is proposed in order to organize various repositories in a hierarchical system. We describe how these objects can be harvested, indexed and retrieved by users from different standard repositories and how to present them to users in different devices. The system was able to index more than 100 thousand Los.
