Yale Data Green is a research data platform that contains a collection of datasets owned and made available by various groups across the university for cloud-based querying and analysis. It is powered by Redivis, a cloud platform.
With built in query and compute goals alongside licensed datasets from across campus, YDG is designed to support both data discovery/exploration and analysis.
Data Green is a central place where Yale researchers can come to for research data, much like the New Haven Green serves a place for New Haven residents to come together.
Redivis is the underlying cloud platform that hosts datasets and provides tools for: dataset storage and access controls, documentation/metadata and versioning, web-based exploration and analysis.
Data Green is geared toward active analysis and controlled access to data. Dataverse is a repository geared toward dissemination and archiving.
Yale Data Green: Optimized for accessing active research datasets that are owned and made available by various research organizations. Users can query, analyze, and collaborate around datasets with access controls and governed use.
Yale Dataverse: A repository for publishing and preserving research outputs (datasets and related materials), often in support of citation, sharing, and long-term access/preservation.
A mix of research-relevant datasets curated or licensed by Yale units and made available for analysis. This can include:
Availability and access vary by dataset.
Typically, Yale affiliates (faculty, staff, students) with an active Yale NetID can request to join a Yale organization. On YDG, an organization is any group that can post and manage datasets. This includes Yale Library as well as other research units across Yale campus, such as the Data Intensive Social Science Center (DISSC). Some collaborations may support access for external partners, but that depends on the specific dataset’s terms and Yale’s access policies.
During Phase 1 of implementation, only Yale Library and Data Intensive Social Science Cetner (DISSC) will be active organizations in Data Green. In Phase 2, set to begin in Fall 2026, other Yale units will be able to join as new organizations to manage their own data. Please contact researchdata@yale.edu if you are interested.

Redivis, the underlying cloud platform behind Yale Data Green, maintains a user guide, available here: https://docs.redivis.com/
Once you log into yale.redivis.com with your Yale netID, you can click “Datasets” on the bottom of the banner and see the titles for all datasets Yale manages in the Data Green.
Datasets in Yale Data Green have different levels of permissions. If you log in with your Yale netID, you will be able to see the titles of all the datasets. For some datasets, you may need to request access via a form to see the metadata and content.
Datasets in Yale Data Green have different requirements, which are listed individually for each dataset. For some, users can download the entire dataset. For others, only a portion may be downloaded.
Please contact marx.reference@yale.edu to talk to Yale Library staff about your data needs.
Almost any tabular data can be added to Yale Data Green, including in CSV, Parquet, or JSON file formats. Some file formats, such as Excel spreadsheets, may need additional work to add to the Data Green, but it is possible. We recommend that any proprietary file formats, like Excel files, be converted into more readily accessible formats whenever possible.
Basic analysis can be performed for free using an environment with base-level RAM and CPU compute resources. Upgrading to more resources may have a cost associated with it, and your needs may be better suited by other Yale environments, such as those at the Yale Center for Research Computing (YCRC). Reach out to Yale Library at researchdata@yale.edu for help determining what resources best fit your needs!
The collaborative coding and analysis workspaces in the Data Green allow sharing of notebooks, queries, and dataset transformations, as well as data assets. The “Studies” feature can be a helpful home base for collaboration and for securely controlling access to your work.

Yes! All datasets on Redivis have built-in version control.
We are transitioning our locally hosted, licensed datasets, prioritizing based on researcher feedback and with consideration of license terms. If you have a specific interest in seeing one of the library’s existing datasets migrated into Yale Data Green please let us know by sending an email to researchdata@yale.edu.
Yale Library hosts many datasets to support researchers and students. We recommend the following resources for help getting started:
Databases By Title, specifically created by our Management, Economics, and Entrepreneurship Librarians, but applicable to many fields.
