Open content, coined by analogy with
open source, describes any kind of creative work (for example, articles, pictures, audio, video, etc.) that is published under a non-restrictive copyright license and format that explicitly allows the copying of the information. (An example is the
GNU Free Documentation License, which is used by
Wikipedia and
Nupedia.) But "open content" also describes content that can be modified by anyone. Of course, this is not without prior review by other participating parties--but there is no closed group like a commercial encyclopedia publisher which is responsible for all the editing.
Just as open source software is sometimes described simply as free software, open content materials can be more briefly described as free materials. See free software movement.
