Open-source film

Open-source films (also known as open-content films and free-content films) are films which are produced and distributed by using free and open-source and open content methodologies. Their sources are freely available and the licenses used meet the demands of the Open Source Initiative (OSI) in terms of freedom.

Definition
A definition of an open-source film is based on the OSI's open-source software definition and the definition of free cultural licenses. This definition can be applied to films where:


 * 1) The license of the movie is approved for free cultural works. Specifically this is true for the Creative Commons licenses by and by-sa.
 * 2) The materials used in the movie (sources) are also available under a license which is approved for free cultural works.
 * 3) The movie and its sources are made publicly available via an online download or by other means that are either free or with a cost that covers reasonable reproduction expenses only.
 * 4) The sources should be viewable and editable with free/open-source software. If this is not the case they must be convertible into such a format by using free/open-source software. The same applies to the movie itself.
 * 5) It should be possible to re-create or re-assemble the movie using the source materials.

Films or film projects which do not meet these criteria are either not open source or partially open source.
