Global - Regional - Local Commons Graph
From P2P Foundation
"One can think of the commons in terms of both level and type. Level connotes the scope of impact or activity. For instance, there are commons on the local, regional, and global levels. Types include the domains of matter (physiosphere), life (biosphere), and mind (noƶsphere)." [1]
