ROR Registry API

ROR (Research Organization Registry) assigns persistent identifiers to research organizations and publishes them via a keyless REST API and CC0 data dumps on Zenodo. ROR’s documentation says: "All ROR IDs and metadata in the data dump are provided under the Creative Commons CC0 1.0 Universal Public Domain Dedication ."

Required Attribution:

Not required (CC0-1.0 public domain dedication).

Coverage

Organization names, ROR IDs, locations and relationships, searchable via the REST API (e.g. `/v2/organizations?query=`) and available in bulk from the Zenodo data dump. "When new releases of the ROR registry are issued, typically at least once a month, the ROR REST API is updated automatically and a new data dump version is uploaded to Zenodo."

Verdict

Open registry of research organizations with persistent ROR IDs, names, locations and relationships, via a keyless JSON API and CC0 dumps. Licensed CC0-1.0. Rate limits: "No registration is currently required to use the ROR API, but note that the rate limit is a maximum of 2000 requests in a 5-minute period per IP address, and API traffic can be quite heavy at popular times like midnight UTC." Client ID registration is temporarily paused: "No rate limits are currently enforced based on the presence or absence of a client ID, and none will be introduced before registration is restored, so API usage is not affected by this pause."
