Commons

Definition
Commons refers to the cultural and natural resources accessible to all members of a society, including natural materials such as air, water, and a habitable earth. These resources are held in common, not owned privately. The resources held in common can include everything from natural resources and common land to software. The commons contains public property and private property, over which people have certain traditional rights. When commonly held property is transformed into private property this process alternatively is termed "enclosure" or more commonly, "privatization."
