General information
URL http://datadryad.org
Description DataDryad.org is a curated general-purpose repository that makes the data underlying scientific publications discoverable, freely reusable, and citable. Dryad is an international repository of data underlying peer-reviewed scientific and medical literature, particularly data for which no specialized repository exists. The content is considered to be integral to the published research. All material in Dryad is associated with a scholarly publication

Dryad performs basic checks on each submission (can the files be opened? Are they free of viruses? Are they free of copyright restrictions? Do they appear to be free of sensitive data?). The completeness and correctness of the metadata (e.g. information about the associated publication, the date on which any embargo is to be lifted, indexing keywords) are checked and the DOI is officially registered.

The data packages are discoverable and backed up for long-term preservation within the DataONE network. The information content of the original file is never intentionally modified or processed, but copies may be made in different file formats to facilitate preservation.

The data package is publicly released once the online version of the associated publication is available (unless an alternative release option has been selected), and the metadata are shared with indexing services to promote discoverability.

Integrity Checksums



Confidentiality Data sets can be embargoed



Dryad does not accept submissions that contain personally identifiable human subject information, since all data is publicly available. Human subject data must be properly anonymized and prepared under applicable legal and ethical guidelines. The following article may be helpful: Hrynaszkiewicz I, Norton ML, Vickers AJ, Altman DG (2010) Preparing raw clinical data for publication: guidance for journal editors, authors, and peer reviewers.

Accepted preferred formats Dryad hosts research data underlying scientific and medical publications. Historically, the repository has been strongest in the life sciences. Most data in the repository is associated with peer-reviewed journal articles, but data associated with non-peer reviewed publications from other reputable sources (such as dissertations and books) is also accepted. At this time, all descriptive information must be in English.

Most types of files can be submitted (e.g., text, spreadsheets, video, photographs, software code) including compressed archives of multiple files. View additional guidance on preservation-friendly file types.
Accepteerde file formats Due to the diversity of datatypes hosted by the repository, Dryad does not require a single file format, or even set of file formats, but rather encourages users to follow accepted community standards where they exist. Users are strongly encouraged to ensure that data can be easily extracted from the files provided (e.g., by using CSV rather than PDF). View additional guidance and a list of preservation-friendly file formats.

Preservation
Long term guarantees See terms of service: http://datadryad.org/themes/Mirage/docs/TermsOfService-A4-2013.08.22.pdf
Long-term preservation by migrating common file formats when older versions become obsolete, and partnering with DataONE to guarantee access to its contents indefinitely.
Complies with international standards for trusted repositories Not certified
Preservation strategy Dryad will maintain its status as a participating publisher with CLOCKSS, which is a certified trusted repository,
(http://www.clockss.org) and maintain a failover copy of all published Content in the CLOCKSS dark archive. In the event that Dryad can no longer maintain the Repository as an
active service, all Dryad-registered DOIs will be updated to resolve to the copy at the
CLOCKSS archive,
Costs
Storage A Data Publishing Charge (DPC) of $90 needs to be paid.
Since a guiding principle of Dryad is to make its contents freely available for research and educational use, there are no access costs for individual users or institutions. Instead, Dryad supports its nonprofit mission by recovering costs up front.

Dryad collects a Data Publishing Charge (DPC) upon publication. The submitter is asked to commit to this charge at the time of submission, and is charged if the accompanying publication is accepted, unless

the associated journal, or another organization, has already contracted with Dryad to cover the DPC, or
the submitter is based in a country classified by the World Bank as a low-income or lower-middle-income economy.
To determine whether your DPC will be covered, look up your journal. If there is no payment plan or sponsor in place, the DPC is $80 for journals with integrated submission, and $90 for non-integrated journals.

Additional charges apply to data packages in excess of 10GB. $15 will be charged for the first GB over 10 and $10 for each additional GB or part thereof.

At this time, we are only able to accept credit cards in payment for DPCs (personal or institutional cards). We regret that we are currently unable to issue invoices for individual submissions.
