DataCite Author Affiliations Matched to ROR IDs - DataCite Enrichment Format

This dataset contains 20,512,320 enrichment records mapping author affiliation strings from DataCite metadata to Research Organization Registry (ROR) identifiers. It covers 5,812,774 unique DOIs from the DataCite Public Data File.

Each record is formatted as a DataCite enrichment input record, designed for use with the DataCite enrichment pipeline. Records use the updateChild action on the creators field, providing a per-creator originalValue/enrichedValue pair that adds ROR identifiers to existing affiliation strings.

Methodology

match-datacite-affiliations-to-ror-ids was used to extract affiliations from the DataCite Public Data File, match them to ROR IDs, and reconcile the results into enrichment records.

1. 1.Unique affiliation strings were extracted from the DataCite Public Data File
2. 2.Each affiliation string was matched to a ROR ID using the single search matching strategy in the ROR API, with v2.3 of the ROR data
3. 3.Matched ROR IDs were reconciled back to individual DOI/author/affiliation records
4. 4.Only creators with at least one successful ROR match are included
5. 5.Affiliations that already had ROR IDs assigned in the source DataCite metadata were excluded from matching
