- Text to be discussed later once we've agreed upon the principle. It can be further explained on this panel. - This pattern is not be confused with the necessity to establish limits on access and use, as needed (see: Cap & Share or Mutualize. E.g., a workshop can be open to all participants but limited in the ultimate number. If demand exceeds limits, the best options are limits based on time, place and access rules, or to replicate and federate (i.e., creation of new commons-based options). Water supply can be open - and even for free - for basic needs, but not open and free for over-consumption based on market-driven demand. (South Africa case?) There is a crucial difference between non-discriminatory access and necessary limits on use of finite physical resources. - Since commons exist within pre-existing systems with different logics, including markets, maintaining commons requires semi-permeable boundaries that allow gradations of control with "outside" forces, especially those involving money and markets.
