Dryad Digital Repository

Tool name: 

Dryad Digital Repository


The ‘Dryad Digital Repository‘ is a curated resource providing a general-purpose location for a wide diversity of data types. Dryad's mission is to make the data underlying scholarly publications discoverable, accessible, understandable, freely reusable, and citable for all users. Dryad originated from an initiative among a group of leading journals and scientific societies in evolutionary biology and ecology to adopt a joint data archiving policy for their publications. Dryad is governed by a non-profit membership organisation. Membership is open to any stakeholder organisation, including but not limited to journals, scientific societies, publishers, research institutions, libraries, and funding organisations.

Pros and Cons of the tool:

The data hosted by Dryad have been dedicated to the public domain under the terms of Creative Commons Zero (CC0) license, in order to minimise legal barriers and maximise the impact on research and education, the terms of reuse are explicit and have some important advantages:

  • Interoperability: Since CC0 is both human and machine-readable, other people and indexing services will automatically be able to determine the terms of use.
  • Universality: CC0 is a single mechanism that is both global and universal, covering all data and all countries. It is also widely recognised.
  • Simplicity: There is no need for humans to make, or respond to, individual data requests, and no need for click-through agreements. This allows more scientists to spend their time doing science. Dryad is based on the DSpace repository software with built-in internationalisation (i18n), automatically translating DSpace text based on the default language of the web browser. 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. Dryad complies with Section 508 of the Rehabilitation Act of 1973. This is a United States federal law, while also being recognised as an international best practice. The Dryad website uses HTML by Section 508 standards and accessibility testing tools to ensure issues are found and fixed when new content features are added. A full overview of integrated journals and costs for submission is provided here.

EU BON recommendations: 

Dryad hosts research data underlying scientific and medical publications. Most data is associated with peer-reviewed journal articles, but data associated with non-peer reviewed publications from other reputable sources (such as dissertations) is also accepted. At this time, all Dryad submissions 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. Ordinarily, no more than 10 GB of material are submitted for a single publication; larger data sets are accepted but will be subject to additional charges.
