One of the positive starts to the new decade has been the Open Data developments where public authorities have been encouraged towards greater transparency by making their data accessible. Leaders here have been the UK and the USA. Germany implemented the PSI Directive with the IWG in December 2006. The IWG is a Federal law which has effect upon Federal authorities, Federal State authorities and municipal bodies alike. This is in contrast to related legislation such as the freedom of information, access to environmental information, consumer information and geoinformation which require implementation at the Federal and Federal State level. This Topic Report gives an overview of the German regulatory framework surrounding PSI re-use and provides a critical assessment of the extent to which it supports an Open Data agenda for Germany.
