  Hardin introduced the notorious concept of "tragedy of the commons". Worrying
about the consequences of human overpopulation on the planet, he discussed
"hard problems": problems with no technical solutions, that can only be
addressed by way of an evolving morality. Hardin's tragedy of the commons
predicts that the hard problem of human population growth directly implies a
hard problem of overuse or pollution of the commons. This paper focuses on the
knowledge commons. A technical proposal is presented, based on a JSON schema
for structuring pieces of knowledge. This is used to show that even if the
knowledge commons satisfies the necessary conditions of the tragedy of the
commons, the ensuing problems are not necessarily hard. Some can be made
trivial by relying on traditional principles implemented in a technical
framework.
