This is true,

I would prefer to use rel="copyright"


because rel="licence" is primarily used for CC licences.

But even so the problem still exists that the rel-copyright still only 
applies to the entire document.

So *maybe* there is need  for something more specific that can be 
related to the object maybe a rel="rights" or something else new..?
