Copyleft Attitude License

Copyleft

The Free Art License published by Copyleft Attitude is an example of a "copyleft" license, which lets users freely distribute copies and modified versions of a work with the stipulation that the same rights be preserved in derivative works created later. The GNU and Creative Commons licenses are other examples, and many other licenses apply the concept to some degree.

• {{FAL}} – Free Art License can be applied to digital as well as to non-digital art. With this Free Art License, you are authorized to copy, distribute and freely transform the work of art while respecting the rights of the originator. The FAL is recommended by the Free Software Foundation: "We don't take the position that artistic or entertainment works must be free, but if you want to make one free, we recommend the Free Art License."

Custom public domain licenses

Many custom public domain licenses are listed at Category:Custom PD license tags. The works may be released into the public domain by an organization or individual, or may be extracts from a major work that is in the public domain, such as the Brockhaus and Efron Encyclopedic Dictionary (1890-1907). A small sample follows.

Copyrighted but may be used

Green copyright symbol

There are many tags for cases where a work is protected by copyright but may be uploaded to Wikimedia Commons using a generic or source-specific license. A small sample follows. See Category:Custom license tags for more licenses like this.

• {{Attribution}} – Copyrighted, but freely usable given the copyright holder is credited. If you are the author of the work, consider using {{Cc-by-4.0}}, instead.
• {{Copyrighted free use}} – Copyrighted, but the copyright holder allows anyone to use it for any purpose. Consider using {{Cc-zero}} for your own work instead.
• {{Free screenshot|license=<free license>}} – for screenshots containing pictures of not copyrighted programs, or programs released under a free license, or by some other way following the requirements of Commons. The actual free license should be indicated as a parameter to the tag. (See {{Screenshot}} for screenshots of copyrighted software or operating systems). If the screenshot shows original work by someone else, make sure it's under a free license and indicate that license using a separate license tag from above. If it shows your own work, say so explicitly and select a license tag of your liking from above.
