Abstract

The semantic web ontology languages RDFS and OWL are widely used but limited in both their expressivity and their support for modularity and integrated documentation. Expressivity, modularity, and documentation of formal knowledge have always been important issues in the MKM community. Therefore, we try to improve these ontology languages by well-tried MKM techniques. Concretely, we propose OM- Doc as an alternative. We show how OMDoc can be made compatible with semantic web ontology languages, focusing on knowledge representation, modular design, documentation, and metadata. We evaluate our technology by re-implementing the Friend-of-a-friend (FOAF) ontology and applying it in a novel metadata framework for technical documents (including ontologies)
