The DataCite measures carry normalized occurrence, distinct DOI-affiliation pair, raw-affiliation-row, and explicit ROR coverage values. DataCite measures are zero for `crossref_only` rows; their ROR values are false, zero, and empty lists. ## Artifact descriptors | Path | Rows | Bytes | SHA-256 | Schema | |---|---:|---:|---|---| |

also recorded in `overlap_metadata.json`. Its ordered steps are: 1. Unicode text is transliterated to ASCII with Unidecode. 2. letters are converted to lowercase. 3. punctuation is removed while internal whitespace is preserved. 4. surrounding whitespace is trimmed; empty results are excluded.
