The SIIF’s IT system features three components: (1) content for the data community (informationneeds and how they are organized); (2) the process for data providers (who does what and how);(3) dissemination for data users (how to display). All of these components have a national andEuropean dimension.This IT development is related to the process and dissemination of the existing content of theEuropean urban waste water data model.The SIIF project opted to implement an open-source IT toolbox. The tool was designed todisseminate environmental data and information at national level but also to facilitate the reportingprocess. It provides EU Member States with a cheap way to implement Article 11 of the INSPIREdirective, and thus to develop a national waste water website. The framework of this website canalso be adapted to correspond to other European Policies.
