document: Online curriculum on the semantic Web : the CSD-UoC portal for peer-to-peer e-learning Online Curriculum Portals aim to support networks of instructors and learners by providing a space of convergence for enhancing peer-to-peer learning interactions among individuals of an educational institution . To this end , effective , open and scalable e-learning systems are required to acquire , store , and share knowledge under the form of learning objects ( LO ) . In this paper , we are interested in exploiting the semantic relationships that characterize these LOs ( e.g. , prerequisite , part-of or see-also ) in order to capture and access individual and group knowledge in conjunction with the learning processes supported by educational institutions . To achieve this functionality , Semantic Web ( e.g. , RDF\/s ) and declarative query languages ( e.g. , RQL ) are employed to represent LOs and their relationships ( e.g. , LOM ) , as well as , to support navigation at the conceptual e-learning Portal space . In this way , different LOs could be presented to the same learners , according to the traversed schema navigation paths ( i.e. , learning paths ) . Using the Apache Jetspeed framework we are able to generate and assemble at run-time portlets ( i.e. , pluggable web components ) for visualizing personalized views as dynamic web pages . Last but not least , both learners and instructors can employ the same Portal GUI for updating semantically described LOs and thus support an open-ended continuum of learning . To the best of our knowledge , the work presented in this paper is the first Online Curriculum Portal platform supporting the aforementioned functionality .
