Hi Jona,
I just want to make one thing clear - if either domain or range has a owl:Thing
"constraint" you don't export that information to the dbpedia.owl? E.g.
location [1] has a owl:Thing constraint for its domain, but it is not available
in the dbpedia_3.9.owl file. It is a problem, since it is not possible to tell
apart missing constraints from a "constraint" that accepts any kind of object.
Cheers,
Aleksander

Are you aware of the DBpedia mappings wiki? Maybe that's a dumb question.
Anyway, once you have a user account, you can add the domain/range here:
http://mappings.dbpedia.org/index.php/OntologyProperty:Genre
and fix the domain (maybe change it from Person to its superclass Agent?) here:
http://mappings.dbpedia.org/index.php/OntologyProperty:Hometown
