What is Dryad and Why Use it?

The Claremont Colleges Library is an institutional member of Dryad, a data repository which provides a platform to help make research data discoverable, freely reusable, and cite-able. Any researcher associated with the Claremont Colleges can deposit datasets from any discipline into Dryad at no cost.  Dryad is one of many data repositories that can be used to share research data.

Frequently Asked Questions

Anyone can submit data into Dryad for a cost. However, our institutional membership means Claremont Colleges researchers can submit datasets for free.

The Claremont Colleges Library provides access to Dryad for students, faculty and staff of Pomona College, Claremont Graduate University, Scripps College, Claremont McKenna College, Harvey Mudd College, Pitzer College, Keck Graduate Institute, the Library, and affiliated scholars.

Dryad used to be for specific disciplines only, but is categorized as a general data repository because it now accepts data from all disciplines. However, if you are submitting data to Dryad to comply with certain publisher or funder requirements, check which data repositories they recommend before submitting your data to Dryad.

No– Dryad no longer requires that data be associated with a publication.

Dryad is for data that is final and publication-ready.

Dryad integrates with several publishers and will link data with publications when they exist. Dryad also recommends that the data be cited in the references of the original publication so that the link between the publication and data is indexed by third-party services

Users can upload datasets that are 300GBs or less through the web interface. Larger datasets will be considered on a case-by-case basis by Dryad. Researchers should contact Dryad at for help.

To upload files into Dryad of more than 10GB, you need to use the “upload by URL” option on the data upload page during submission. If the files can be stored on Box, Dropbox, Amazon, or a lab server, that would be the easiest way to transfer them over. Direct upload of files over 10GB files are not allowed because of servers time-out issues.

Currently, only files less than 3GB will effectively transfer from Google Drive to Dryad.

Dryad currently only offers a CC0 license.

Data in Dryad is openly discoverable and downloadable. Data cannot contain any sensitive, restricted, or confidential information.

Dryad offers the option to make the dataset private during a related article’s peer review process.

Dryad tracks download, views, and citation metrics.

Dryad offers “light-weight” curation for all datasets to make data more FAIR (Findable, Accessible, Interoperable, Reusable). In the future, we may offer more support locally for data curation from Claremont Colleges researchers.

Dryad reserves a DOI immediately when a depositor begins a dataset submission, which is why the DOI appears on page 3 of the data submission process. The DOI is registered and can be resolved as soon as something is published, which occurs once the Dryad staff completes their data curation step (Dryad estimates this step to take 1-2 weeks). The DOI is unresolvable during the curation process, but Dryad reserves the DOI up front in case people need to provide it to a journal or update a DMP.

The institutional membership comes with services from the Dryad team such as hosting the platform, software updates, storage hardware maintenance, curation, waived data publication costs for Claremont researchers, and perpetual data hosting. These are attractive to us. Additionally, we are interested in their upcoming plans for integrations with 1) journals, 2) funders, and 3) Zenodo. Dryad is also flexible with local customization, which is something we’d like to explore in the future.

No. As mentioned above, Dryad may not be the best solution for all of our researchers. If there is a disciplinary repository, we always recommend that you use that for greater visibility and impact. There may also be considerations depending on if you are grant funded, and/or if you are working with a publisher. Choosing a repository solution currently is not a one size fits all, and the Library is here to consult and offer advice when making these decisions.
