The property has multiple domains i.e. Event, MediaObject, Movie, MusicRecording. For example, schema.org/Movie also > uses schema:duration. Maybe we should have renamed 'runtime' to > 'duration' instead? We could create specific properties for each domain and link them to schema:duration (maybe as subproperties). In this way, we can keep 'runtime' just for movies.

There is an official OWL [1] as well as an RDFS [2], but I don't know whether they are actually used or not. For example, schema:duration doesn't have a > dereferencable URI yet.
In conclusion, the open question is: should we try to reuse existing ontology terms i.e. schema.org or add new ones under the dbpedia namespace?
