The course starts with the basic notions underlying the Wikidata ontology and goes on to cover querying using SPARQL, inference, constraints, advanced ontology notions, problems with the ontology, and other ontology-related aspects of Wikidata. Participants in the course are expected to complete weekly exercise sets and a project. More information on the course can be found at WikiProject Ontology/Ontology Course.
