Elinor Ostrom's Eight Design Principles for Managing a Commons (per Nordman):

• The physical and social boundaries are clearly defined;

• Locally tailored rules define resource access and consumption;

• Individuals who are most affected by the rules can participate in rule making;

• Resource monitors are accountable to resource users;

• Graduated penalties can be imposed on rule breakers;

• Conflict management institutions are accessible;

• Authorities recognize the right to self-organize;

• Complex systems are organized into layers of nested governance.

Ostrom developed these through the study and analyzing of about 5000 examples of common-pool resource management around the world. The ones that were successful, had some version of these.
