Semantic Document Management for Collaborative Learning Object Authoring

In this paper, we propose the use of semantic documents as learning objects. The core part of our solution is a semantic document model that allows for unique identification of document content units (CUs) and their annotation with different types of metadata. On the top this model, we have developed the semantic document management system (SDMS), which enables efficient collaborative authoring of learning objects within a social network of content authors, by reusing document CUs based on the accumulated metadata.
