This is a proposal for a new Type: Thing > CreativeWork > VisualArtwork
I am aware that there are already sub-Types for "Painting", "Sculpture", and "Photograph", but this doesn't seem like a viable way forward. There are many other types of artwork (printmaking, drawing, collage, assemblage, digital art, etc.) and it seems illogical to create new Types for each artform.
So my proposal is for the 'VisualArtwork' Type to be used instead of "Painting" or "Sculpture", and instead of "Photograph" where the photograph in question is being presented in context as an artwork as opposed to forensic photography, etc.
A number of additional properties enable would allow a wider range of visual artwork media to use this type, and provide more information about the artwork being described.
A draft machine-readable schema is available.
