Archiving

The Johns Hopkins Research Data Repository is an open access repository for the long-term management and preservation of research data. Through depositing datasets in the Johns Hopkins Research Data Repository, researchers are able to share their research data with the public for future discovery and reuse. The Johns Hopkins Research Data Repository is administered by professional curators, who will work with you to ensure your data is Findable, Accessible, Interoperable and Reusable (FAIR).

The Johns Hopkins Research Data Repository offers free data archiving for JHU researchers. Our Data Management Consultants offer personalized curation services that many public data archives do not, helping to prepare your data for long-term preservation and use. Our curators also manage access to archived data, store backup copies, and run quality checks on archived data for a minimum of five years. 

The Johns Hopkins Research Data Repository accepts data in any format and from any discipline, making the Johns Hopkins Research Data Repository a great option for fields that do not have a discipline-specific public repository. Some fields of research have developed repositories and databases specialized for their data types and topics. It is often preferable to deposit to specialized databases when appropriate, for better discovery by those in your field. Certain funders and grants may specify particular repositories. Our consultants can help you locate appropriate specialized repositories if available and assist in the deposit processes. 

All datasets in the Johns Hopkins Research Data Repository have a persistent identifier (DOI) and a suggested citation, ensuring your data is findable, accessible, reusable and citable. 

We recommend depositing the materials behind any findings, summary tables, and visualizations in your publication or research project. These materials, collectively called “data,” can include cleaned or processed data files used for analysis; code used to process or analyze your data; simulations; survey responses; interview transcripts; researcher observations; geospatial vector files; information computationally derived from public sources, and more. In short, data are all the files and scripts that would help a researcher reuse your data or reproduce the findings of your publication.  

Please note that if your data contain Protected Health Information (PHI) or Personally Identifiable Information (PII), this information must be removed or de-identified prior to depositing data to us. Contact us at dataservices@jhu.edu with any questions about human subject data deposits. 

All datasets in the Johns Hopkins Research Data Repository have a persistent identifier (DOI) and a suggested citation, ensuring your data is findable, accessible, reusable and citable. 

The Johns Hopkins Research Data Repository accepts only public access data with any personal and health identifiers removed, meeting HIPAA’s “Expert/Statistical Determination” criteria for de-identification. Contact us to discuss whether your data can be archived with us, alternative options, and to review your de-identification protocol. (Never email us human subject data even if you consider it de-identified.) To learn more about de-identification check out our online guide, Protecting and Removing Human Subject Identifiers.   

Yes, it is free for up to 1TB for users who are affiliated with JHU divisions that participate in our funding model. You can find the list of participating divisions here. We will charge a fee if

• Your data is more than 1 TB
• Your division is not listed in our participating divisions

If one of your affiliation or one of your data collection’s authors is with a school that participates in DMS funding, you will be able to archive up to 1TB of research data with us for free. Otherwise, please contact JHU Data Service for more details and fee information. 

Yes, we do! We offer options to mint one DOI, a bulk of DOIs (up to 10), and a dedicated DOI account for researchers. Please visit our DOI services page to view more details. 

No, Johns Hopkins Research Data Repository is not intended as storage for active research data. Its purpose is to provide open access to others interested in referencing and using research your data, and long-term preservation. You can contact your Department IT or JHU Central IT, if you are looking for a place to store and share research data with your lab members and/or collaborators.  

The 1 TB limit applies to each project or dataset in the Johns Hopkins Research Data Repository. To qualify for free archiving, all the files for a single data collection must be under the 1 TB limit. If an individual PI has multiple data collections that, if combined, would exceed 1 TB, they will still qualify for free archiving if each of their project is under 1 TB.

Please contact JHU Data Service for more details and fee information.  

In general, the whole process will take about one or two business week. The length of our archiving process depends on the quality of your documentation and how fast you can turn in the required forms and upload files. Visit our Archiving Steps page to learn more.  

We strongly advise that you provide information about your data. The more complete the description of your datasets, the more likely that someone will be able to find, understand, trust, and reuse your data. If you want to learn more about how to document your research, check out our series of online modules here.    

We currently don’t offer the option to embargo your data. However, your data collection is always private until you give us the approval to publish it online. If your manuscript is still under review and you want to hold onto publishing your data until the manuscript is accepted, we can offer you a private URL that you can share with your reviewer(s), even the data collection has not been published yet.  

Datasets in the Johns Hopkins Research Data Repository currently supports only public open access, not requiring registration from those accessing and download data. Open access meets funder and publisher preferences. If your data requires restricted access, please contact for help finding a data repository that best meets your needs. 

You can use the following language but adopt it according to your situation: “Long-term archiving of data will be managed by Johns Hopkins Data Services (JHUDS) using the Johns Hopkins Research Data Repository. The Data Repository provides public access to data through an established repository platform supported by storage and preservation practices that follow the Open Archival Information System reference model. Deposited data is given standard data citations and persistent identifiers (DOIs). JHUDS provides system administration and consultative support for researchers preparing data for deposit. Data will be archived under a memorandum of understanding renewed every 5 years with the PI’s consent.” 

No, the Johns Hopkins Research Data Repository welcomes data associated with a publication and datasets that are archived and shared on their own.
