They are especially useful in Linked Data and RDF knowledge bases that 1) rely on SPARQL querying and 2) require semantic support for chains of relations. ...
These knowledge bases integrate both data, like Kegg, and ontologies, like Gene Ontology, in the same RDF graphs. ...
Conclusion The use of MDGs, annotated with terms about relations in Metarel, enables a bridge between graphbased representations like RDF and DL-based representations like OWL. ...
