The document describes the ARIADNE experience in sharing and reusing learning resources. It discusses key technologies like metadata, harvesting, federated search, and publishing that allow learning resources to be described, collected, searched across repositories, and added to repositories. The ARIADNE infrastructure provides services like validation, transformation, harvesting, and access tools to facilitate open sharing of over 1 million learning objects among various projects and repositories around the world using open standards.
