RORThe Research Organization Registry (ROR) is a community-led, open registry that assigns persistent identifiers to research organizations worldwide. Launched in 2019, ROR addresses the longstanding challenge of consistently and unambiguously identifying the institutions behind scholarly research, complementing ORCID (for individual researchers) and DOI (for research outputs).
Background
The need for a standardized organizational identifier emerged as research became increasingly global and collaborative. Before ROR, the Global Research Identifier Database (GRID) served as the primary open registry for research institutions, but its proprietary ownership raised sustainability concerns. In 2019, a coalition of three organizations — the California Digital Library (CDL), Crossref, and DataCite — established ROR as an open, community-governed alternative. The registry was initially seeded with data from GRID. In 2021, GRID announced that ROR would take over as the leading open organization identifier, and ROR's first fully independent release was published in March 2022.
Purpose & Scope
ROR provides a unique URL-based identifier (e.g., https://ror.org/03yrm5c26) for each research organization in the registry, currently covering over 116,000 institutions. The registry focuses on organizations that produce, fund, or support research — including universities, government labs, hospitals, nonprofits, and companies. Each ROR record includes the organization's name, aliases, location, website, and cross-references to other identifier systems such as ISNI, Crossref Funder Registry, and Wikidata.
Data Model & Access
ROR data is structured as JSON records accessible through three channels: a search-enabled website, a REST API, and downloadable data dumps published on Zenodo. Each record contains the organization's canonical name, alternate names (including names in other languages), geographic coordinates, country, organizational type, and relationships to parent or child organizations. All ROR IDs and metadata are released under the CC0 public domain dedication.
Governance & Maintenance
ROR is jointly operated by the California Digital Library, Crossref, and DataCite. The registry follows an open curation model where anyone can suggest additions or corrections through a public request system. A dedicated curation team reviews submissions, and updates are published in versioned releases. The project is funded through a sustainability model supported by the three operating organizations and their respective communities.
Notable Implementations
ROR IDs are integrated into major research infrastructure systems including Crossref metadata, DataCite DOI registrations, OpenAlex, ORCID, and numerous institutional repository platforms. Funding agencies and publishers increasingly use ROR to standardize affiliation data in grant applications and manuscript submissions. The Wikidata property P6782 links Wikidata items to their corresponding ROR identifiers.
