I publish photos under multiple Creative Commons licenses and often want to indicate the licensing in a short caption or comment on the photo online or in print. If one of them is dual licensed, how can I represent that in a way that will be recognized by as many people as possible?
My naive approach has been to simply concatenate the license names with
|| as a separator (example:
CC-BY-SA || CC-BY-NC), which indicates a logical OR to me, but might mean nothing to non-programmers.
