A Metadata Model for Web Services Applied to Index and Discover E-Learning Services

摘要

In this paper, we propose a metadata model for indexing learning services. We propose to describe and index learning services with three dimensions: 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 yellow 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.
