# ROR Identifier DOI Distribution
## Summary
`ror_identifier_doi_distribution.json` provides an inventory of every ROR (or ROR-formatted) identifier in the August 2025 DataCite data file. Each entry describes how many affiliation rows inlcude the identifier, the list
of unique DOIs, and which providers/clients asserted it.
## Structure
```json
{
"identifier": "https://ror.org/01abc1234",
"occurrences": 512,
"dois": ["10.1234/abc", "10.1234/xyz"],
"providers": {"unique_total": 6, "counts": {"tib.example": 300, "cdr.sample": 212}},
"clients": {"unique_total": 5, "counts": {"example.client": 512}}
}
```
### Fields
- `identifier` *(string)*: normalized ROR URL.
- `occurrences` *(int)*: count of affiliation rows that used the identifier.
- `dois` *(array)*: sorted, unique DOIs referencing the identifier.
- `providers` / `clients` *(object)*: per-entity assertion counts plus `unique_total`.
