Licensing is giving permission for someone to use something. This category of the P2P Foundation Wiki covers a number of different aspects of licensing including reviews of licenses and licensing groups that serve creators throughout the world.

Christian Siefkes on the three freedoms characteristic of Copyleft licenses:

   * The freedom to use the work for any purpose.
   * The freedom to study the work and to change it to make it to do what you wish.
   * The freedom to distribute and share the work with others, so that the whole community may benefit.

Combinations of the three freedoms must be possible, too. The Free Software Definition specifies a fourth freedom that combines the preceding two (distribute modified versions).

Copyleft ensures that the three freedoms will also hold for all derived works: I may only published derivative versions if I give all their users the same rights." (
