An idea for an alternative schema.org type for artwork

This is my first draft of an idea of how to mark up artwork using Schema.org. It is intended to replace both http://schema.org/Painting and http://schema.org/Sculpture (and http://schema.org/Photograph when it is being used to describe photographs in an artistic context rather than photojournalism, snapshots, etc.)

My desire to create a new Schema.org type for artwork came about because of my annoyance with the limited vocabulary in the currently available types (most notably, the lack of a type for printmaking and drawing).

I should state that this is just an idea of mine – it is not an accepted way to use Schema.org markup and so should not be used on a production website!

Schema.org tools may have only weaker understanding of extra types, in particular those defined externally.
