The project aims to increase the volume and quality of open public data and to increase the re-use of data at the disposal of public bodies. It is a continuation and development of systemic activities implemented in the project Open Data – access, standard, education (OD-DSE). 5 databases of project partners will be opened by API. On data.gov. pl tools will be introduced to facilitate the management and coordination of the process of opening data. There will be reports of recommendations aimed at systematising and expertly supporting the process of opening data in central offices. Educational activities will continue for people who deal with and share public data on a daily basis, extended to more advanced topics and practical aspects. Information on the potential and benefits of data opened within the framework of the project, the data.gov.pl portal that makes these data available, as well as the possibilities of their reuse will be disseminated.
