In Genre

Connects a work to the art form that names its genre, such as painting, sculpture, film, dance or manuscript illumination. The inverse reading, Genre Of, names the same relationship from the art form toward each work classified under it. This relation type gives the genre classification already recorded as an enum fact on each work a durable, comparable entity identity; it does not replace that enum fact, which keeps classifying every work exactly as before, and it is kept separate from the In Form relation so the two classifications stay independent.
