I think in moving images, and I don't think moving images are objects. I place these moving images in domain names. Each URL is the title and the location of each art piece. These websites are public, their ownership is exclusive. Domain names are one of the internet’s few scarcities. They are unique, they can't be forged or copied.
This contract explains the rights and duties of the artist and the collector, to make sure the work remains intact as long as possible. It was drafted by Aernoud Bourdrez, attorney at law.
