Data availability statement policy

Mandatory data availability statement policy

IOP Publishing encourages authors to make the data underpinning their article available to editors, referees and readers without undue restriction, wherever practical, legal and ethical to do so.

Authors must provide a data availability statement in their article, detailing whether data are available and, if so, where they can be found (including hyperlinks where available). Authors can make small amounts of data available within the article or as supplementary material, while larger datasets should be deposited in an institutional or general data repository. We encourage the use of publicly-accessible repositories where available. Authors of accepted articles in these journals may deposit their data and/or code free-of-charge in the IOP Publishing Figshare repository by following the link supplied during the article submission process.

As a trial, a mandatory data availability statement policy is currently being applied in the following journals:

  • Environmental Research Letters
  • JPhys Complexity
  • Machine Learning: Science and Technology

Permissible formats for data availability statements

Data availability statements should follow one of the following formats and should appear in their own section of the manuscript, between the Acknowledgments and the References.
