Data Deposit Requirements of Selected Science Journals
An important principle of science is that experiments or studies should be reproducible by someone working independently. In order for this to occur, data that is the basis of research findings must be available. Explicit statements of data deposit requirements from some major scientific journals are included below to illustrate this expectation.
Dryad is an international repository of data underlying peer-reviewed articles in the basic and applied biosciences. Dryad enables scientists to validate published findings, explore new analysis methodologies, repurpose data for research questions unanticipated by the original authors, and perform synthetic studies. Dryad is governed by a consortium of journals that collaboratively promote data archiving and ensure the sustainability of the repository.
The Open Data Policy section of Author guidelines states that "to allow others to verify and build on the work published in Royal Society journals, it is a condition of publication that authors make available the data, code and research materials supporting the results in the article."
A condition of publication in a Nature journal is that authors are required to make materials, data and associated protocols promptly available to others without undue qualifications. Data sets must be made freely available to readers from the date of publication, and must be provided to editors and peer-reviewers at submission, for the purposes of evaluating the manuscript.
PLoS Editorial and Publishing Policy states that "PLOS is committed to ensuring the availability of data and materials that underpin any articles published in PLOS journals. PLOS's ideal is to make all data relevant to a given article and all readily replaceable materials immediately available without restrictions (while not compromising confidentiality in the context of human-subject research)."
Science supports databases that aggregate published data for the use of the scientific community stating that "all data necessary to understand, assess, and extend the conclusions of the manuscript must be available to any reader of Science". A list of approved databases is provided in the Data and Materials Availability section of the General Information for Authors.
