Terms of Service

Updated: July 26, 2019

These Terms of Service apply to Individuals and Organizations who use or publish content on the Dryad Data Platform, pay for others to publish content (whether through vouchers, deferred payment plans, subscriptions or otherwise), or obtain and reuse content from the Dryad Data Platform. These terms apply with equal force to Individuals and Organizations using the web interface or an application programming interface to the Dryad Data Platform.

By submitting content to or using content from the Dryad Data Platform, submitters and users enter into a binding agreement to accept the Terms of Service described herein. If you do not agree to these Terms of Service, please refrain from using content from or submitting content to the Platform.

If there is any conflict between the Organization Membership Agreement and these Terms, the Organization Membership Agreement will prevail.

Guiding these Terms of Service are Dryad's aims to:

2. Publication Policies

2.1 Content Criteria

Dryad only Accepts Content that meet the following criteria:

2.2 Embargos

2.3 Expressions of Concern, Retraction and Removal of Data Files

If there is an associated Document, Dryad generally defers authority to the Document publisher when issues arise regarding validity of Content. If Content on the Platform is associated with a Document for which there is an "expression of concern," "retraction," or similar statement on the part of the Document publisher, Dryad will continue to make the Content available, but with an appropriate warning and a link to the statement from the Document publisher. Data files that are updated as corrections to the original paper will be similarly linked to the publisher's corrigendum where Dryad is made aware of such.

Those who wish to see Content on the platform taken down, either for copyright infringement, because of privacy concerns, or for other legitimate cause, should contact providing the following:

  1. A physical or electronic signature of a person authorized to act on behalf of the owner of an exclusive right that is allegedly infringed;
  2. Identification of the work claimed to have been infringed, or, if multiple works at a single online site are covered by a single notification, a representative list of such works at that site;
  3. Identification of the material that is claimed to be infringing or to be the subject of infringing activity and that is to be removed or access to which is to be disabled, and information reasonably sufficient to permit the service provider to locate the material;
  4. Information reasonably sufficient to permit the service provider to contact the complaining party, such as an address, telephone number, and, if available, an electronic mail address at which the complaining party may be contacted;
  5. A statement that the complaining party has a good faith belief that use of the material in the manner complained of is not authorized by the owner, its agent, or the law;
  6. A statement that the information in the notification is accurate, and under penalty of perjury, that the complaining party is authorized to act on behalf of the owner of an exclusive right that is allegedly infringed.

Notwithstanding the foregoing, Dryad reserves the right to temporarily or permanently remove any Content at any time if Dryad determines in its sole discretion that the Content is inappropriate (containing personally identifiable, sensitive, infringing or otherwise illegal material, or Dryad is advised by legal counsel that inclusion of such Content presents a potential risk to Dryad); provided, however, Dryad shall not be responsible for screening Content prior to or after its Publication for such issues. Dryad agrees to notify Submitter if Content is rejected or removed and the reasons related to the removal.

2.4 Large files

During the process of submission and review, and with the knowledge and consent of the Submitter, unusually large files that are within the scope of another repository may be transferred for archiving by Dryad to that secondary repository without retention of a copy on the Platform.

3. Dryad Obligations, Representations and Warranties to Purchasers and Submitters

3.1 Curation

Dryad curation personnel will provide Submitter support and will review and curate Content prior to and following Publication as follows:

  1. Confirm that files can be opened, are not corrupted, and do not contain viruses which can be discovered through commercially reasonable efforts;
  2. Confirm that metadata for the Document is technically correct;
  3. Confirm administrative metadata including, but not limited to, the embargo release date where applicable;
  4. Confirm that files are correctly versioned during the Review Workflow where applicable, and review updates to files and metadata Submitted either before or after Publication;
  5. Confirm that the Submission is covered by a Waiver or Payment Plan where applicable;
  6. Register Digital Object Identifiers (DOIs) for the Content;
  7. Resolve issues that come to the attention of curators after Publication including, but not limited to take-down requests and retraction notices.

Dryad may, but is under no obligation to:

  1. Review Content for personally identifiable or otherwise sensitive or inappropriate information;
  2. Review Content for copyright and license statements that are potentially incompatible with a CC0 Waiver;
  3. Review Content for compliance with file format and minimum reporting guidelines and alert Submitters or publishers when non-compliance is discovered.

Dryad will not:

  1. Make decisions regarding what Content is to be archived by the Document publisher rather than Submitted to the Platform;
  2. Check the scientific validity, veracity, accuracy or completeness of the Content;
  3. Guarantee compliance with content policies or guidelines set by Purchasers, Document publishers or funders in the absence of a separate contract for special curation services;
  4. Modify Content except as a by-product of format migration for preservation and accessibility.

3.2 Content Distribution

3.3 Preservation

Dryad aims to maintain the integrity, availability and reusability of its Content over the long term. Note that it remains the responsibility of Submitters to provide sufficient metadata and background information in order to facilitate Users' understanding of the data.

This policy is informed by the Open Archival Information System (OAIS) reference model (ISO 14721:2012) ( which defines "long term" to be a period of time long enough for there to be concern about the impacts of changing technologies, including support for new media and data formats, and of a changing user community.

3.3.1 Preferred formats and format support levels

While Dryad Accepts all data types and formats within reason, some formats are preferred. Curators may contact Submitters to request a file in an alternate format, and/or Dryad may save additional versions of files that have been transformed to preferred formats. Non-proprietary, openly documented formats are preferred if the format does not compromise reuse potential. Dryad recognizes that some formats may be preferred for reusability even if not ideal for preservation.

Preferred file formats:

Format support levels:

  1. Full support: Dryad will make a best effort to ensure the properties and behaviors into the future of Content submitted in a preferred format or other common format as enumerated below, including future format migration.
    • Office: Open Office (ODS, ODP, ODT), Microsoft Office (DOC, DOCX, XLS, XLSX, PPT, PPTX)
    • Markup: HTML/XHTML, XML, Nexus formats (NEX, NEXML)
    • Image: PDF/A, JPEG/JPEG2000, PNG, GIF, TIFF, SVG (no Java)
    • Audio: FLAC, AIFF, WAV, MP3
    • Video: AVI, M-JPEG2000, MP4
  2. Limited support: For uncommon formats for which we are less confident there will be robust conversion tools, Dryad will make some effort to ensure the future readability and functionality, but there may be some loss. Examples would include PDF files that are not compliant with the requirements of PDF/A.
  3. As-is bitstream access: For binary files from proprietary instrumentation and software and other exotic formats, Dryad preserves the bitstream as-is and makes no commitment to format transformation or future usability.

3.3.2 Procedures for preservation

Dryad aims to preserve the originally submitted Content indefinitely. Steps to ensure long-term availability include:

3.3.3 Security

Full backup copies of Platform Contents are stored in multiple secure facilities offsite. All deposits to Dryad are sent to a CoreTrustSeal-certified preservation repository called Merritt. Merritt distributes backup copies through cloud and physical locations globally. For further details on Merritt’s process and certification, see:

3.3.4 Versioning

Dryad Datasets may be Versioned in order to correct errors in the archived files or to provide additional data associated with the analysis reported in the associated Document.

(Datasets between 50 and 60GB = $50, between 60 and 70GB = $100, and so on). These fees are subject to change as posted to

Submitters also are responsible for paying any third-party costs associated with Submission of the Content (e.g. fee to use a large file transfer service external to Dryad).

For planning and scientific review purposes, Dryad will keep records of usage. Dryad makes available to the public information about aggregate usage of Datasets. Logs of usage may also be maintained for the purposes of monitoring and improving services, or measuring the impact of a particular function on our resources. These logs may be made available, after anonymization, to third parties. Usage of the Dryad website indicates agreement to the use of a Google Analytics cookie.

Dryad may automatically collect and store the following information not generally considered "personally identifiable" from Users or Submitters who access Dryad Content directly or indirectly, including:

8.2 Personally Provided Information

Users who do not Submit Content to Dryad are not asked to provide any personally identifying information.

The Platform shall not store or record any Purchaser's credit card, debit card, bank account or any other form of payment account information on its servers.

Researchers creating data submissions will login to Dryad via ORCID; researchers affiliated with a Member institution will use a single sign in process via Shibboleth. Personal identifiable information is used by Dryad to conduct and improve core services including billing, and responding to customer help requests. We may contact submitters with information or questions directly related to their use of the Platform service.

Publishing organizations and the Platform may send automated notices to each other as part of Submission Integration; these communications may convey personally identifiable information regarding authors and Submitters that will only be accessed by staff as required to provide services.

If Users or Submitters choose to provide Dryad with additional personally identifiable information through an email message, form, survey, etc., Dryad will maintain the information securely to the extent allowable by law and take every precaution to protect it. However, Dryad will treat feedback on services and software provided by Dryad, excluding personally identifiable information, as non-confidential unless the individual or organization providing the feedback states otherwise.

8.3 Security and Intrusion Detection

Dryad implements and follows commercially reasonable electronic security measures to secure the systems through which information is collected or stored. Security protections, and all other elements of this policy, extend to data copies and backups implemented for business continuity.

For site security purposes, and to ensure that this service remains available to all Users, we employ software programs to monitor traffic and to identify unauthorized attempts to upload or change information or to otherwise cause damage. In the event of authorized law enforcement investigations, and pursuant to any required legal process, information from these sources may be used to help identify an individual.

8.4 Disclosure of Personally Identifiable information

Aggregate information or individual information that does not personally identify a user can be shared with third parties without restriction. One such third party is Google Analytics, (see their privacy policy), which is used to understand how the website is being used.

Dryad will only disclose individually identifiable personal information about its users under the following restricted circumstances:

8.5 Privacy Protection Limits

Referrals to external sites: Dryad's web services may link to Internet sites and services outside the administrative domain of Dryad.
