Authors are recommended to make the research data that reinforce their publications available but are not obliged to do so. The decision to publish a paper will not be affected by whether or not authors share their research data.

This policy refers to the research data that would be needed to verify the results of research reported in articles published. Research data include data produced by the authors (“primary data”) and data from other sources that are analysed by authors in their study (“secondary data”). Research data comprise any recorded factual materials that are employed to produce the results and draw conclusions. They may be raw and/or processed data, tabular data, images, maps, audio- or video- documents, etc.

The data that are not a subject to public disclosure may be delivered as follows: deposited in science data repositories with limited access or preliminary anonymised. An author can also publicly deliver metadata only and/or description of the method of access to the data under requests from other scholars. The preferred mechanism for sharing research data is via data repositories. Please see https://www.re3data.org/ for help finding research data repositories.
