The Research Organization Registry (ROR) includes IDs and metadata for more than 102,000 organizations and counting. Registry data is CC0 and openly available via a search interface, REST API, and data dump. Registry updates are curated through a community process and released on a rolling basis.

ROR is the only organization identifier that is completely open, focused specifically on affiliations, operated as a community initiative, and supported in core scholarly infrastructure.
