ROR (Research Organization Registry) API

Overview

ROR is the community-led registry of open persistent identifiers for research organizations worldwide — 110,000+ entries covering universities, research institutes, government agencies, hospitals, and companies. The API enables affiliation disambiguation, institutional search, and metadata retrieval. Essential for bibliometrics, funder compliance, and research analytics. Free, no authentication required.

# Example: find German research institutes

# Example: disambiguate messy affiliations

      f"{result.get('names', [{}])[0].get('value')}")

Use Cases

1. Affiliation disambiguation: Clean messy author affiliation strings
2. Bibliometric analysis: Aggregate publications by institution
3. Funder compliance: Link outputs to institutional identifiers
4. Research profiling: Map institutional research portfolios
5. Collaboration networks: Trace inter-institutional partnerships
