The document discusses two types of open data pricing models - Type I, which provides open data for free with no quality assurances, and Type II, which provides quality-assured public sector information (PSI) at a cost-plus price. It introduces a third model, Type III, which provides both open data and PSI depending on service level agreements, and uses marginal cost pricing to cover infrastructure costs. The document promotes taking open data reuse to the next level and provides contact information for the author to discuss further.
