This work describes the application of semantic wikis in distant learning for Semantic Web courses. The resulting system focuses its application of existing and new wiki technology in making a wiki-based interface that demonstrates Semantic Web features. A new layer of wiki technology, called “OWL Wiki Forms” is introduced for this Semantic Web functionality in the wiki interface. This new functionality includes a form-based interface for editing Semantic Web ontologies. The wiki then includes appropriate data from these ontologies to extend existing wiki RDF export. It also includes ontology-driven creation of data entry and browsing interfaces for the wiki itself. As a wiki, the system provides the student an educational tool that students can use anywhere while still sharing access with the instructor and, optionally, other students.

    Inferencing in infobox displays
    rdfs:domain -> property in template and form
    owl:symmetricProperty -> in infobox both ends of triple
    Inferencing in Forms input
    rdfs:range -> Semantic Forms autocompletion parameters

    MediaWiki for teacher access
    The more on the wiki the better
    The Semantic Web in the wiki
    Remains an “extra” tool for students
    Future work
    More SPARQL usage: internal & external
    Fresnel integration
    Additional semantic browsing features
    Continued integration with new extensions
