title = "A federated authorization service for bridging learning object distribution models",
abstract = "In a large federation of commercial learning object repositories, customers might be confronted to different access control procedures put in place by different content providers to enforce their respective distribution models. This paper proposes a federated authorization service that provides a uniform access to learning objects protected by different authorization protocols. This service is based on a learning object broker that mediates different distribution models.",
