The document discusses the proposed revision of the PSI (Public Sector Information) Directive, which aims to promote the reuse of public sector data. The key changes proposed include creating a genuine right to reuse public data, lowering the charging ceiling to marginal costs, shifting the burden of proving compliance with charging rules to public bodies, and requiring independent supervision of the rules. The expected impacts are higher incentives for PSI reuse leading to more competition and innovation, increased public efficiency and data quality, and indirect economic benefits for Europe estimated at €140 billion from further opening up public sector information.
