The main aim of this work is to improve the usability of the OBA-MC by implementing a learning object repository. The OBA-MC is a learning object model created from the Content Map and Dependency Map tools, whose creation process is a methodology for subject planning. To develop the repository, a block was implemented in the Moodle virtual learning environment. This block contains a menu for the inherent functionalities of a repository, such as importing, exporting and listing objects.
