# DataCite 2026-07 Exact Affiliation Usage

This dataset contains exact, case-sensitive affiliation strings from both
DataCite creators and contributors. Every placement contributes one occurrence
count; repeated placements on a DOI are retained. DOI count is distinct per
exact affiliation.

## Contents

- Distinct DataCite DOIs, including DOI records without affiliations: 132,801,254
- Valid DOI source records (DOI stream rows): 132,801,303
- Valid affiliation occurrences: 334,593,737
- Exact affiliation rows: 1,681,662
- Distinct DOI-affiliation pairs: 112,023,092
- Split: train
- Train schema v3: exact affiliation totals plus explicit valid and invalid ROR
  attribution support. `ror_ids` contains canonical ROR IDs with occurrence and
  distinct-DOI support; `most_common_ror_ids_*` retain all lexical tie winners.
- Sidecars: artifacts/doi-affiliation-attributions-*.parquet records each exact
  DOI-affiliation-status attribution group, and
  artifacts/doi-prefix-population-*.parquet records DOI-prefix source populations.

## Normalized affiliations

The `normalized` split uses `comet-datacite-ascii-v1`: Unicode text is
transliterated to ASCII, lowercased, stripped of punctuation while preserving
internal whitespace, and trimmed. Empty results are excluded. Its columns are
`normalized_affiliation` (string), `total_occurrence_count` (uint64),
`raw_affiliation_count` (uint64), and `doi_count` (uint64), plus explicit ROR
coverage and deterministic ROR support lists. DOI counts are calculated from
the DOI-affiliation attribution sidecar after normalization, so one DOI shared
by multiple exact variants is counted once for the normalized key. Compact
per-prefix attribution rows are published under
`artifacts/normalized-prefix-attribution-*.parquet`.
