Aligned ISNI and Ringgold identifiers for institutions

  • 1. CAPSH


This dataset provides a correspondence between ISNI and Ringgold identifiers, by combining two datasets:

  1. Open ISNI for Institutions, available at , which provides metadata for institutions identified by ISNI.
  2. The dataset of institutions used by ORCID for disambiguation, which also comes from Ringgold, but exposes Ringgold ids.

The alignment between the two datasets was performed by exact matching on tuples of (name,city,region,country). This very conservative matching succeeds for 316,870 of the 499,658 institutions covered (as of June 2019, when the extraction was performed): this relatively high matching rate can be explained by the fact that both datasets come from the same database. Matching fails in other cases because of metadata differences which might be introduced by ORCID's own workflow.

Structure of the dataset

  • ringgold_ids.tsv.bz2 provides all the Ringgold ids we could extract from ORCID, with their metadata (locality, region, country, type);
  • aligned_ringgold_and_isni.tsv.bz2 provides the aligned dataset, containing all ISNI records and all matching Ringgold ids. The Ringgold ids that were not matched are not included in this file.


Quoting Ringgold: "The use of the ISNI data contained herein is completely open and you may utilise and share the ISNI identifiers as you see fit."

Quoting ORCID: "Per our agreement with Ringgold, we are allowed to share the Ringgold identifiers and limited metadata (organization name, location) under CC0 license, just as the rest of ORCID data are available. We would not be using Ringgold otherwise. If someone gets a Ringgold ID out of ORCID, they are free to use it."
