Need a place to share your research data publicly for a publication or after you have finished your research project? All Johns Hopkins researchers can use the JHU Data Archive to meet their funder and/or journal data sharing requirement.
The benefits of using the JHU Data Archive:
- Offers free archiving for projects under 1TB for JHU schools which participate in DMS funding (list of participant DMS funding)
- Accepts data from any research discipline and file format (Note: Human subject dataset require full de-identification for public access before archiving with us)
- Provides each dataset with a permanent citation and a persistent identifier (DOI), facilitating both attribution of authors and linkage to research publications
- Preserves research data through regularly checking file integrity and retaining multiple copies
- Data is managed, maintained and preserved by our professional curators
If you are considering archiving and sharing data via JHU Data Archive, please follow the steps below to start the process:
Step 1: Decide what to share
- Does your research involve human subjects? Have you fully de-identified these data? Please contact us (via firstname.lastname@example.org) for guidance on sharing your human subject data. Sharing medical research at the JHU Data Archive may require approval from the Data Trust Council. We also have an online guide about data de-identification, Protecting and Removing Human Subject Identifiers.
- Would you like to share software and/or analysis code?
- What is the total size of your data sets?
- Do you have proper documentation for your data? Have you attached a ReadMe file with your data?
Step 2: Contact JHU Data Services to start the archiving process. You will hear back from us within 2 business days.
- You will receive a deposit agreement and a deposit form from us. Please fill, sign, and return it to us.
- Deposit Agreement: Sign and return to JHU Data Services. This form states the responsibilities of JHU Data Services and researcher. If you are a student or postdoc, please have your lab’s PI sign this form.
- Deposit Form: Provides information about your data sets and/or code so we can properly document your research products.
- We will setup a JH OneDrive folder for you to upload your data files, code and documentation. If your data size is too large for an online transfer, we can arrange alternatives for transferring large datasets.
Step 3: Once you have filled out all forms and uploaded your data files, we will create a data collection for you in the JHU Data Archive (We can provide data citations with DOIs If needed for publication references prior to releasing data). You will have a chance to review your data collection before we publish it online.

JHU Data Archive FAQs
What is the JHU Data Archive?
The JHU Data Archive is an open access repository for the long-term management and preservation of research data. Through depositing datasets in the JHU Data Archive, researchers are able to share their research data with the public for future discovery and reuse. The JHU Data Archive is administered by professional curators, who will work with you to ensure your data is Findable, Accessible, Interoperable and Reusable (FAIR).
Find the archive at https://archive.data.jhu.edu/.
Why should I archive my data with JHU Data Archive, instead of FigShare, Zenodo, Dryad, etc.?
The JHU Data Archive 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 JHU Data Archive accepts data in any format and from any discipline, making the JHU Data Archive 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 JHU Data Archive have a persistent identifier (DOI) and a suggested citation, ensuring your data is findable, accessible, reusable and citable.
What should I do if I have human subject data?
The JHU Data Archive 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.)
Is the JHU Data Archive free for all JHU affiliates?
What if the school that I am affiliated with does not participate in DMS funding?
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.
I am interested in getting a DOI for my data, but don’t want to upload/share data in JHU Data Archive. Do you provide a service to just mint a DOI for me?
Can I store my data with JHU Data Archive and only share them with my lab members and/or collaborators?
No, JHU Data Archive 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.
What does this 1 TB limit apply to?
The 1 TB limit applies to each project or dataset in the JHU Data Archive. 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.
What should I do if my data is larger than 1 TB?
Please contact JHU Data Service for more details and fee information.
How long does the whole process take?
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.
Can I just upload my data without providing any information about my data?
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.
Can I embargo my data or require users to register first before downloading data?
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 JHU Data Archive 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.
I plan to share my data via the JHU Data Archive and would like to write this into my Data Management Plan. Do you have any language that I could use in my DMP?
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 JHU Data Archive. The Archive 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.”
Do I need to have a published article to be able to archive my data?
