The other is to the take example of schema.org/Book which has a genre property which accepts a text string instead of having a plethora of subClasses such as ScienceFictionBook, FantasyBook, Romance, LiteraryFictionBook, Western, Thriller, ReferenceBook, Textbook, Biography, etc. This enables a wide range of types of book to be marked up without the need to maintain a lot of new subClasses, and is my preferred option as it allows easier mapping to other systems such as CDWA, VRA CORE, etc. > > So if acceptance of new subClasses of VisualArtwork would be limited > to those that need additional values, wouldn't that help keep the > amount of types needed/expected reasonable? I'd note that the existing Painting and Sculpture types don't have any additional properties, so what would be the premise for having them as subClasses? > > "They served a purpose in the past, but I think that their purpose > has been superseded and are probably due for retirement." > > > Oh, that very well could be, I haven't got any numbers at my disposal > which show if these two types are published a lot or not.
