Federated authentication and authorization for reusable learning objects

The LiLa (Library of Labs) project goal is to combine virtual laboratories and remote experiments spread out over Europe, which will be shared and exchanged among educational institutions in the form of reusable learning objects. This work addresses the needs of authentication and authorization when reusable learning objects are exported from an experiment provider organization to an experiment user Learning Management System. The paper discusses possible solutions based on using the SCORM run-time environment specification as a framework for learning objects and Shibboleth as a framework for a federated authentication and authorization.
