While the Public Domain Mark is not intended to be used as a license, community consensus has found that when a copyright holder applies the PDM to their own work, they are declaring their work to be in the public domain.
If a file is tagged PDM by someone other than the copyright holder, a more specific copyright tag such as one found at Commons:Copyright tags/General public domain must be applied. If this is your own work, please use {{Cc-zero}} instead.
