The Open Knowledge Foundation is an english non-for-profit organization whose objective is to promote open knowledge, defined as:
Any content, information or data that people are free to use, re-use and redistribute — without any legal, technological or social restriction. The main principles are:
1. Free and open access to the material
2. Freedom to redistribute the material
3. Freedom to reuse the material
4. No restriction of the above based on who someone is (e.g. their nationality) or their field of endeavour (e.g. commercial or non-commercial)
The main purpose seems to be to apply to culture and knowledge the same principles that were developed for free and open source software. To achieve their objectives they work on several projects, a couple of which revolve around the idea of open data and open government too.
