A metadata model for Web services applied to index and discover E-Learning Services
Résumé
In this paper, we propose a metadata model for indexing learning services. We propose to de-scribe and index learning services with three di-mensions: as learning resources, as services that contribute and help researchers and as general services. They can be used by clients (learners or teachers) to query and discover services via yel-low pages like UDDI or a trader. We have used ontologies and knowledge representation to index and store the characteristics of services. The association of an ontology and knowledge representation provides a powerful combination.
