Learning Object Virtualization Allowing for Learning Object Assessments and Suggestions for Use

Works presented in this paper offer teachers and learners the opportunity to express their learning objects assessments and suggestions for use directly from a learning management system, and to store these annotations within a learning object repository. Annotations are thus stored when and where they become relevant. Thanks to an open and standardized architecture, these annotations can be widely shared and exploited in various contexts such as re-authoring, curriculum designs, or learning object retrieval. Indeed, annotations can represent a basis for a (personalized) quality-based sorting mechanism helping users to find and reuse learning resources that match with their preferences. An implementation focusing on Moodle and the Ariadne knowledge pool system validates our approach.
