The document discusses the ARIADNE project, which aims to facilitate sharing and reuse of learning resources. It describes several ARIADNE services including a repository, registry, harvesting tools, and federated search. The services use open standards and specifications to store, search, transform, validate and aggregate metadata and learning resources. ARIADNE also provides tools to access resources visually, through multi-touch, augmented reality, and bridges to integrate with other systems like Moodle.
