DataCite Affiliation Assertions

Summary

This dataset packages three JSON arrays derived from the August 2025 DataCite data file: affiliations_with_ror.json, affiliations_without_ror.json, and affiliation_overlap.json. Together they capture the complete set of affiliation strings, their ROR identifier assignment patterns, and the overlap between assigned and unassigned occurrences. Each record also reports the number of distinct providers and clients asserting that affiliation.

Structure

Each JSON object has the following form (fields vary slightly by file):

{
  "affiliation": "Example University",
  "occurrences": 120,
  "providers": {"unique_total": 4, "counts": {"tib.example": 70, "cdr.other": 50}},
  "clients": {"unique_total": 3, "counts": {"example.client": 120}},
  "ror_assignments": {"https://ror.org/01abc1234": 120}
}

affiliation_overlap.json replaces occurrences with assigned_occurrences, unassigned_occurrences, and identifier_occurrences (ROR counts).

Fields

• affiliation (string): canonical affiliation string as observed in the DataCite export.
• occurrences (int): total times this affiliation appeared with a ROR assignment (missing only in overlap file).
• assigned_occurrences (int, overlap only): number of times a ROR identifier was present.
• unassigned_occurrences (int, overlap only): number of times no identifier was supplied.
• identifier_occurrences (object, overlap only): map of ROR (or other) identifiers to occurrence counts.
• providers / clients (object): unique_total plus per-ID counts of who asserted the affiliation.
• ror_assignments (object, with_ror only): map of identifier → occurrence counts.
