+# 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):
+
+```json
+{
+  "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.
