How to Share and Reuse Learning Resources: the ARIADNE Experience
Download as KEY, PDF1 like403 views
This document discusses the ARIADNE experience in sharing and reusing learning resources. It describes the key technologies used in ARIADNE including metadata standards, harvesting protocols, federated search, and publishing interfaces. It provides examples of metadata validation, transformation, and harvesting workflows. ARIADNE services including repository software, validation tools, harvesting, and federated search are presented. Software quality attributes and performance results are evaluated. The conclusion discusses the open, standards-based architecture and its ability to integrate and manage learning objects across applications.
