Scientific data and their opening


Scientific data are data collected, observed or produced as material for analysis, in order to obtain original scientific results: components of experiments performed, samples, results from laboratory apparatus, photographs, descriptions of field research, statistical data, observational data, software, methodological descriptions, surveys, etc.

Definition of scientific data taken from Directive 2019/1024 of the EU Parliament and of the Council of 20 June 2019. – Article 2.9: documents in a digital form, other than scientific publications, which are collected or produced in the course of scientific research activities and are used as evidence in the research process, or are commonly accepted in the research community as necessary to validate research findings and results;


The opening of scientific data is already included in a legal framework in Poland (Act of 11 August 2021 on Open Data and Reuse of Public Sector Information).

The essential rationale for applying Open Access to research data as well:

  • everything funded with public money should be publicly available
  • cost-effectiveness – more than 80% of data is never reused
  • the owner of research data is not the researcher, but his/her home institution
  • non-open access to research data is of course permissible, but must be justified (e.g. intention to commercialise, objections due to third party rights)
