The JDAP is a policy of required deposition to be adopted in a coordinated fashion by Dryad partner journals. The Joint Data Archiving Policy (JDAP) is distinct from Dryad. However, it is recognized that Dryad is designed in order to make the JDAP easier, and without JDAP there would likely be limited adoption of Dryad; thus the two efforts are mutually reinforcing. The following wording was agreed upon by the Dryad Consortium Management Board:
<< Journal >> requires, as a condition for publication, that data supporting the results in the paper should be archived in an appropriate public archive, such as << list of approved archives here >>. Data are important products of the scientific enterprise, and they should be preserved and usable for decades in the future. Authors may elect to have the data publicly available at time of publication, or, if the technology of the archive allows, may opt to embargo access to the data for a period up to a year after publication. Exceptions may be granted at the discretion of the editor, especially for sensitive information such as human subject data or the location of endangered species.
The journals behind the JDAP are committed to minimizing the burden on authors, while ensuring that important data is permanently archived.
No, only the data required to support the claims made in the publication need to be archived. Of course, you are welcome to archive as much of it as you like.
The use of data carries the same intellectual debt as citation of a published paper. Any reuse of the data must cite the original paper from which it was derived.
Data may be placed under embargo at the time it is archived, allowing you to prepare additional publications from the same original data. The JDAP (and Dryad) allows each data file to be placed under embargo for a period of one year from the publication of the associated article.
