Include attribution in metadata?

Some CC licensed works include specific instructions for how they want to be attributed. This is an example:

http://commons.wikimedia.org/w/api.php?action=query&titles=File:-Fernsehstudio-Journalistengespraech-crop.jpg&prop=imageinfo&iiprop=extmetadata

(check the Attribution metadata field). It would be interesting to see how this kind of information could be expressed using W3C Media Annotations so that it can be picked up and used by Elog.io.
