Commons:Creative Commons copyright tags
This project page in other languages:
This page lists all Creative Commons licenses that are accepted at Wikimedia Commons. Under our licensing policy, only "by-sa" (Attribution-ShareAlike), "by" (Attribution), and "sa" (ShareAlike) licenses are permitted; all "nc" (Noncommercial) and "nd" (No Derivatives) licenses are not acceptable.
Empty cells denote licenses that do not exist. Text in a cell means the license exists, and if the license template is blue, it actually exists on Wikimedia Commons. Each license is followed by an external link to its Creative Commons deed. This table was compiled with a script that examined every possible license permutation on the Creative Commons website. See the discussion for details.
