What kind of data can I deposit?

UNC Dataverse accepts all types of data; however, it offers optimized preservation for certain file types such as Stata, R, SPSS, and some Excel file types. Dataverse processes these optimized preservation file types during ingest and creates a software agnostic tab-delimited version as well as an RData version of the file for long-term access and preservation. Optimized preservation also permits users the ability to explore these file types within the UNC Dataverse interface.

While UNC Dataverse can preserve all file types at the bit-level, it may not be the best data repository option for certain data types. If you are uncertain if UNC Dataverse is the best data repository for your research data, please Submit a Help Ticket to request a free consultation.

What are the recommended data file types I should provide?

The file formats used by researchers are often informed by individual research practices and domain-specific standards. However, to avoid risks to long-term data preservation, access, and use that can arise from software obsolescence, the Odum Institute Research Data Archive Management Core recommends that data files be submitted in formats that are widely adopted, non-proprietary, free of external software dependencies, and well-documented.

The following file formats are supported with optimized preservation:

When using the above file formats, UNC Dataverse will generate a software agnostic, tab-delimited (TSV) version of your data files for optimal preservation. Dataverse also creates an Rdata version of your data to permit users the option to download the file in an open source format.

The following file formats for document files such as README files, codebooks/data dictionaries, instruments, and methodology reports are recommended:

Are there file size limits?

UNC Dataverse accepts self-deposit uploads of 2 GB per file. For individual files over 2GB in size, please Submit a Help Ticket for assistance or alternative storage solutions.

Can I share sensitive data within the UNC Dataverse?

UNC Dataverse cannot store or share sensitive data containing identifiable information such as protected health information (PHI) or personal identifiable information (PII). We recommend using the Safe Harbor or other approved methods for de-identifying data before depositing into UNC Dataverse. If your data cannot be de-identified, please Submit a Help Ticket to request a consultation to help identify alternative solutions to sharing and preserving sensitive data.

Yes. UNC Dataverse offers access controls to Admin and Curator roles of your dataset(s). Individual files can be restricted, and access requests can be enabled to permit UNC Dataverse account holders the ability to request access to each file through UNC Dataverse. To learn more about access restrictions, please see the Access Controls for Data section (link) of the Getting Started (link) guide.

How long are files stored in UNC Dataverse?

Files are stored in perpetuity. The Odum Institute Data Archive and UNC Dataverse are members is a member of Data-PASS, a community dedicated to the preservation of research data. As such, we have implemented a Digital Preservation Policy which defines our succession plan for continued access to our holdings.

Can I remove my datasets from UNC Dataverse?

UNC Dataverse is an open data repository for sharing and preserving research data. All published data are given a persistent unique identifier (DOI), which directs users to the permanent published dataset record. In most instances, we would not recommend removing data from UNC Dataverse; however, if data are discovered to be too sensitive or in violation of copyright or terms of use, Odum Institute Data Archivists RDMC staff will remove the data from UNC Dataverse.
