Public Domain isn't truly a license, per se. The definition of what is in the public domain varies from country to country, as is whether or not the author of a work can place his/her work voluntarily in the public domain. If a work is in the public domain, no-one owns the copyright to the work, and/or (usually) anyone can use, copy, modify, redistribute, or otherwise exploit the work for any purpose. |
