OntologyClass talk:Genre

The class Genre has subclasses: MovieGenre MusicGenre

There are also LiteraryGenres such as Satire http://dbpedia.org/page/Satire which is currently marked up as a MusicGenre, but is primarily a literary genre.

How does one go about adding a subclass?

I, for one, would create a subclass LiteraryGenre. Next, you could then add subclasses for Sarire, Novels etc.
