Recent research on web-based educational systems attempts to meet the growing needs
and expectations of the education community concerning e-learning efficiency, flexibility,
and adaptation by employing ontologies and Semantic Web standards and paradigms.
These advanced technologies allow for more intelligent access and management
of web information and semantically richer modelling of content, applications, and
users. Within the educational field, they motivate efforts to achieve semantically rich,
well-structured, standardised, and verified learning content and learning activities that
can be shared and reused by others. Conceptualizations, ontologies, the available W3C
standards such as XML, RDF(S), OWL, OWL-S and educational standards such as
LOM, SCORM, and IMS-LD allow specification of components in a standard way.
The standards-based machine-processable semantic descriptions of web resources provide
the necessary ground for achieving reusability, shareability, and interoperability of
educational web resources and better personalization in educational hypermedia and
web-based applications.
