Non-software Use
The principles of open source have been adapted for many forms of user generated content and technology, including open source hardware, Wikipedia, and open access publishing.
Supporters of the open content movement advocate some restrictions of use, requirements to share changes, and attribution to other authors of the work.
This “culture” or ideology takes the view that the principles apply more generally to facilitate concurrent input of different agendas, approaches and priorities, in contrast with more centralized models of development such as those typically used in commercial companies.http://en.wikipedia.org
