The repository

The repository: Key features

  • Flexible about data format, while encouraging the use and further development of community standards.
  • Fits into the manuscript submission workflow of its partner journals, making data submission easy.
  • Gives journals the option of making data privately available during peer review and of allowing submitters to set limited-term embargoes post-publication.
  • Data are linked both to and from the corresponding publication and, where appropriate, to and from select specialized data repositories (e.g. GenBank).
  • Assigns data Digital Object Identifiers (DOIs) to data so that researchers can gain professional credit through data citation.
  • Promotes data visibility by allowing content to be indexed, searched and retrieved through interfaces designed for both humans and computers.
  • Contents are free to download and have no legal barriers to reuse.
  • Contents are curated to ensure the validity of the files and metadata.
  • Submitters may update datafiles when corrections or additions are desired, without overwriting the original version linked from the article.
  • Long-term preservation ... by migrating common file formats when older versions become obsolete and partnering with Data Archiving and Networked Services (DANS) and DataONE to guarantee access to its contents indefinitely.

The repository: Technology

  • The original version of Dryad was built upon the open-source DSpace repository software. All customizations not available within the main DSpace distribution are available from the Dryad code repository under an open source (new BSD) license.
  • The version of Dryad released in fall 2019 is based on the Dash software developed by the California Digital Library. All code is available from the CDL-Dryad code repository
  • Dryad supports multiple ways of receiving article or manuscript metadata from publishers. The simplest method involves reading email notifications, but we are also implementing a REST API for those desiring greater control over the data deposition process.
  • Digital Object Identifers provided by DataCite
  • Terms of reuse provided by Creative Commons
  • Information on programmatic access to Dryad's data is available on the Dryad wiki.


Accessibility statement

Dryad’s vision is to promote a world where research data is openly available, integrated with the scholarly literature, and routinely re-used to create knowledge. Our mission is to provide the infrastructure for, and promote the re-use of, data underlying the scholarly literature.

We believe that universal design and adherence to coding standards are the best means to ensure access to the broadest possible audience, and our design and development staff work together to achieve those goals.

DSpace internationalization

The DSpace repository software used by Dryad has built-in internationalization (i18n). This feature automatically translates DSpace text based on the default language of the web browser. Some customized parts of the Dryad website are only available in English at this time.

Section 508 compliance

Section 508 of the Rehabilitation Act of 1973 is a United States federal law, while also being recognized as an international best practice. To ensure that we meet or exceed the requirements of Section 508, Dryad continually reviews our site and modifies pages to remove accessibility problems for people with disabilities.

Our website uses HTML that follows Section 508 standards; for example, we include alternate text to describe graphics. We use accessibility testing tools to help us find and fix issues whenever we add new features of content.

For more detailed information on the 508 compliance status of the Dryad website, please see our Voluntary Product Accessibility Template® (Dryad-VPAT.PDF  (opens in a new application)).

Accessibility of Dryad contents

The Dryad Repository does not impose any file format restrictions. As a result, Dryad cannot guarantee that all files in all data packages are accessible. However, we encourage authors to submit data in formats such as ASCII and HTML that are not only accessible to screen reading software, but also more suitable for preservation and reuse.

What to do if you have a problem

If you have a problem accessing any information on the Dryad website, please contact and we will work to resolve the problem.
