The journal encourages/requests authors to share research data required for confirming the results published in the manuscript and/or enhance the published manuscript under the principle ‘as open as possible, as closed as necessary. We accept supporting software applications, high-resolution images, background datasets, sound or video clips, large appendices, data tables and other relevant items that cannot be included in the article.

Authors may submit data together with the manuscript submission. In this case, the data will be made available to reviewers and published once the manuscript is accepted for publication online (e.g., on the general-purpose data repository Zenodo). Each data file will be assigned a DOI, enabling the data to be cited the same way as traditional publications. Note that these materials will not be copy-edited or typeset: their appearance and format is entirely the author’s responsibility.
