Marks that say what somebody else may do with a work. Unlike most groups in this catalogue these make legal claims, and three distinctions inside the group are load-bearing: the plain Creative Commons badge carries no terms at all without the condition marks beside it, CC0 is a waiver of rights rather than a licence granting permissions, and the copyleft C has no legal force whatever — a work is copyleft because of the licence it carries, not because of that symbol. Grouped so a reader who has seen one of them on a photograph can find out what it actually obliges them to do.
