Elinor Ostrom's 8 rules for managing The Commons

1. Commons need to have clearly defined boundaries.
2. Rules should fit local circumstances.
3. Participatory decision-making is vital.
4. Commons must be monitored.
5. Sanctions for those who abuse the commons should be graduated.
6. Conflict resolution should be easily accessible.
7. Commons need the right to organise.
8. Commons work best when nested within larger networks.

This is part of defining a commons ala David Bollier and Peter Linebaugh
