From Silos to Ecosystems: Connecting Digital Objects with Common PIDs to Improve Discoverability Across Generalist Repositories

Across the global research landscape, keeping knowledge connected requires robust, common standards across platforms. The US National Institutes of Health (NIH) Generalist Repository Ecosystem Initiative (GREI) represents a unique "coopetition" model, bringing together seven established generalist repositories (Dataverse, Dryad, Figshare, Mendeley Data, Open Science Framework, Vivli, and Zenodo) to enhance data repository infrastructure support for improved NIH data sharing and reuse. A key component of this initiative is the development and implementation of common metadata standards including the use of PIDs to improve interoperability, discovery, and long‑term stewardship of research outputs. This presentation will detail GREI’s collaborative journey to implement common Persistent Identifiers (PIDs) including DataCite Digital Object Identifiers (DOIs) for datasets, ORCID iDs for researchers, and Research Organization Registry (ROR) IDs for author affiliations and funders across the GREI repositories.
