Restricted to literary and artistic works?Edit
A public domain date can only apply to literary and artistic works, databases (in some jurisdiction), inventions (in case of patents). It cannot be applied to persons as the term of protection for works created by that person might differ per work. Can we restrict this property to disallow its use at persons?
