About Duke's Research Data Repository
The Research Data Repository is a program area of the Duke Digital Repository (DDR) and is provided by the Duke University Libraries as a place for the Duke community to publish and preserve digital data for long-term access and future use. All data go through a curation process to help ensure data are well described, in a structure and format that supports long-term preservation, and generally meet the FAIR Guiding Principles for data (i.e., Findable, Accessible, Interoperable, and Reusable) (Wilkinson, et al., 2016) Learn more about our curation services or contact us if you have questions. All data and documentation are openly accessible for download unless under embargo.

Who can deposit materials?
Data deposit in the DDR is open to all members of the Duke Community for their research data with a valid netid.
What types of materials can they deposit?
Research data are the original sources or materials (born digital or converted to digital) that were created or gathered in the process of your research. They serve as the foundation from which you draw conclusions and produce results/findings (test hypotheses, study trends, provide evidence, refute claims). They may be numeric or qualitative, structured or unstructured. Among many possible forms, data may take the form of notebooks, statistical or spatial data tables, audio or visual recordings, photographs or models. The end-results/findings of your research such as monographs, articles, white papers, or presentations are not considered research data.
- Data related to the teaching and research mission of Duke University including data linked to a publication, research project, and/or class
- Supplementary software code and documentation used to provide context for the data
What types of materials are out of scope for this area?
- Data for which the depositor cannot reasonably assert a license governing usage and access to the data.
- Data that contain sensitive, restricted, or confidential information (i.e., personally identifiable information, protected health information, export-controlled information, etc.)
- Data that do not include a minimal level of description necessary for the operation of the DDR.
- Dynamic data (continuously updated data) are outside the scope of the DDR, however, the DDR will consider archiving snapshots and significant versions of these types of data.
If your data are out of scope for the DDR, we are happy to help you identify an appropriate repository, contact us at firstname.lastname@example.org
The Duke Faculty Handbook mandates that:
"Research records should be archived for a minimum of five years after final reporting or publication of a project (or longer if required by an external sponsor, law, rule or regulation)."
Deposit in the DDR will fulfill the terms of the Duke Faculty Handbook. Additionally, deposit in the DDR will also fulfill many of the data sharing requirements as set forth in federal data sharing mandates.
Data Deposit Agreement
What you agree to:
By depositing this Content ("Content") in the Duke Digital Repository ("DDR"), you agree that you are solely responsible for any consequences of uploading this Content to the DDR and making it publicly available, and you represent and warrant that:
- You are either the sole creator and the owner of the copyrights and all other rights in the Content; or, if not the sole creator, you have the right to deposit the Content in an archive such as the DDR either based on the rightsholder’s express permission or as permitted by law. Additionally, you agree that the Content does not infringe the copyrights or other intellectual property rights of someone else, is not defamatory, and does not violate any laws or another's rights of privacy or publicity.
- You agree to provide your data under one of the standardized licenses identified in the DDR Licensing Policy.
- The Content contains no restricted, private, confidential, or otherwise protected data or information that should not be publicly shared, and that the deposit and sharing of this Content complies with any applicable IRB protocol.
- The Content is in a final state and is not subject to revisions or updates.
- Nothing in the Content contains any software viruses or computer codes, files, or programs capable of allowing unauthorized access or disrupting, damaging, limiting or interfering with the proper functioning of the DDR or other users' software, hardware, or telecommunications equipment.
What we agree to:
You understand that the DDR will do its best to provide perpetual access to your Content. The DDR will, consistent with the standardized license selected by you, provide access, reproduce, distribute and publicly display the Content, in whole or in part, in order to secure, preserve and make it publicly available. DDR may also migrate the Content to other media or formats, or make other copies to preserve its public access.
While DDR will do its best to provide perpetual access to deposited Content, DDR makes no promises or warranties that this Content will be perpetually or consistently preserved or accessible. In addition, DDR reserves the right to remove Content under the terms of its deaccession policy for reasons such as deposits made in conflict with terms of this license, in response to a valid DMCA notice, or in response to a valid court order compelling the removal of such Content.
Acceptable Use Policy
What users of files agree to:
- You will not attempt to identify any individuals included in the data or otherwise infringe the privacy or confidentiality rights of individuals discovered inadvertently or intentionally in the data
- If you should identify anyone unintentionally, you will contact the Duke Digital Repository at email@example.com
- You will abide by the Creative Commons license conditions applied to the data (if any).
- You will properly cite the data by including a data citation in any publication or presentation resulting from use of the data.
Content within the files are governed by the DDR Data Deposit Agreement. Data are offered with no warranty or claim of fitness for any purpose. In no event shall Duke University be liable for any actual, incidental or consequential damages arising from use of these files.
If you discover that a link is broken or that you are not able to download the files you need, please contact firstname.lastname@example.org.
A license helps secondary users understand how they can or cannot use your data. The default waiver suggested for research data deposited within the Duke Digital Repository is a CC0 public domain dedication. The CC0 waiver reduces many legal and technical obstacles to data reuse that can arise from applying other licenses (such as attribution stacking). Since in many jurisdictions data may not be copyrightable, the CC0 waiver also removes legal questions related to the copyright status of datasets. While the CC0 waiver does not require attribution, growing community and data citation norms create an expectation that users will properly cite data in the same manner they would any other form of scholarly communication.
If releasing your data into the public domain is not appropriate, data depositors may elect to apply another Creative Commons license to their data. We encourage data depositors to carefully consider both their rights to assign a license to the data as well as what license might be required by other stakeholders including funders and journals. If you have questions about licensing your data, please contact email@example.com or the Duke Libraries Office of Copyright and Scholarly Communications (firstname.lastname@example.org).
Pricing for Storage
As of January 1, 2017, all Faculty are entitled to deposit research data into the Duke Digital Repository up to 2.5 GB for unsponsored projects or 10 GB for sponsored projects for preservation. Additional preservation-level storage can be provided at the cost of:
- $0.282/GB per year billed annually
- $1.41/GB one time for five (5) years of preservation
- $1.97/GB one time for seven (7) years of preservation
- $7.05/GB one time for perpetual preservation
Duke graduate students, postdoctoral staff, or other Duke staff members who do not have a faculty member as a co-author or co-creator of their research data, qualify for 1.5 GB of storage for unsponsored projects and 5 GB of storage for sponsored projects. Any student with storage needs above this allocation will require a faculty sponsor to facilitate the payment of the additional preservation costs as listed above.
These costs will be updated annually to reflect any changes in costs and can be used for project and grant budgets. These costs reflect the direct cost of storage only. The Libraries do not charge for administrative overhead or indirect costs for this service.
The Duke Digital Repository has outlined its commitment to the long-term preservation and persistent access to the University's digital assets curated in the Duke Digital Repository (DDR) within the DDR Preservation Policy. The primary preservation strategies for the DDR include bit-level preservation including fixity checking and version control, geographically disparate copies, file formats and obsolescence management, and information security. To learn more, consult the complete DDR Preservation Policy.
Persistent identifiers are long-lasting references to a document, file, web page, or other object, usually digital. Typically, these references may be entered into a web browser and will resolve to the specified resource. All objects in the Research Data Repository are assigned an Archival Resource Key (ARK) on ingest, which will serve as the basis for a persistent link to each object in the data package. Additionally, datasets will be assigned a Digital Object Identifier at the level of the complete data package, which will be included in the dataset citation and will provide persistent access to the data.
The purpose of the Duke Digital Repository is to allow open, immediate access to Duke research data. It is understood that there are times when immediate access may need to be delayed. To meet this need, the Duke Digital Repository allows depositors to delay publication (embargo) of a full dataset (all data and documentation) for up to one year from time of deposit. During the embargo period, a descriptive metadata record for the dataset will be made publicly discoverable in the repository that includes a Digital Object Identifier (DOI) and the date on which the files will be made available. Contact email@example.com if you need to apply an embargo to a dataset.
As outlined within the DDR Data Deposit Agreement, data producers should make every attempt to ensure that data deposited within the DDR is in its final publication-ready state. However, we also understand that errors may be discovered post-publication or additional data or documentation files may need to be added. In these cases, the DDR staff can help you create a new version of your dataset. We will continue to provide access to the previous version of all files to ensure persistent access to previously published materials (if you need to permanently remove files, see deaccessioning below). Versioning should not be used as a method to add files to a collection from different waves of a study or as a method to preserve data during the active research phase of a project. If you foresee your dataset evolving over time then consider a "release cycle" for your data. If you need to version content already within the DDR or have questions about creating a plan for publishing dynamic data, contact firstname.lastname@example.org.
The mission of the Duke Digital Repositories (DDR) is to ensure the long-term integrity and accessibility of its contents. If for some legal or ethical reason (such as discovering the inadvertent disclosure of sensitive information) you need to permanently remove files from the DDR, please reference our Deaccession and DMCA Takedown Policy and complete the Deaccession Request Form. When files are removed from the repository a "tombstone" metadata page will remain providing a provenance record for the persistent identifier (DOI).
