ROR data

ROR started with seed data from Digital Science’s GRID database and began assigning ROR IDs to 91,000+ organizations. ROR updates its records when GRID releases a new database update. Ultimately the two registries will diverge. ROR records map to GRID IDs (along with other identifiers) and vice-versa.

ROR records include basic metadata about an organization (including name, alternate names, and location). Additional metadata will be added in the coming months. ROR can support multiple languages and character sets (here is an example: https://ror.org/01k4yrm29).

All ROR IDs and metadata are provided under the Creative Commons CC0 1.0 Universal Public Domain Dedication.


The ROR minimal viable registry (MVR) includes the following components:

ROR ID (Example: https://ror.org/03yrm5c26) - Expressed as a URL that resolves to the organization’s record
- Unique and opaque character string: leading 0 followed by 6 characters and a 2-digit checksum
- Crosswalks with other identifiers for the organization (GRID, ISNI, Crossref Funder Registry, Wikidata)

Affiliation use case

ROR’s focus is the “affiliation use case” - identifying which organizations are associated with which research outputs. We use “affiliation” to describe any formal relationship between a researcher and an organization associated with researchers, including but not limited to their employer, educator, funder, or scholarly society.

Criteria for inclusion in ROR

ROR is a registry of “research organizations.” We define the “research organization” as any organization that conducts, produces, manages, or touches research. This is in line with ROR’s stated scope, which is to address the affiliation use case and be able to connect organizations to research outputs. 

Relationship to other identifiers

ROR is interoperable with other identifiers. ROR IDs map to GRID, ISNI, Crossref Funder ID, and Wikidata.

For ROR to be useful, it needs to augment the current offerings in a way that is open, trusted, complementary, and collaborative, and not intentionally competitive. We are committed to providing a service that the community finds helpful and not duplicative, and enables as many connections as possible between organization records across systems.

Some aspects of ROR that make it different from other identifiers are that the registry is (a) community-led, (b) completely open, and (c) focused specifically on the affiliation use case.

Granularity and hierarchy

ROR is focused on being a top-level registry of organizations so we can address the fundamental affiliation use case, and provide a critical source of metadata that can interoperate with other institutional identifiers.

Requesting changes to ROR records

Email info@ror.org to request an update to an existing record in ROR or request that a new record be added. We are formalizing data management policies and procedures in the next stage of the project.

Operations and governance

An MVR (minimum viable registry) ROR launched in January 2019. ROR operations are administered by California Digital Library, Crossref, and DataCite and advised by a larger steering group. The ROR steering group is responsible for strategic decision-making about governance, sustainability, and overall project direction.

There is also a community advisory group of 40+ volunteers from across the research sector and they are looking at issues like data curation, policies, adoption, and engagement. ROR supporters have also contributed financially.
