One row per (file x release) from the final fatcat bulk export (2024-02-18, Internet Archive; fatcat.wiki is offline). Sorted by sha256, so hash point-lookups read one row group:

SELECT title, doi, wayback_url
FROM 'hf://datasets/david-ar/fatcat-files/data/*.parquet'
WHERE sha256 = '...';

maps/sha1.parquet and maps/md5.parquet (sorted by key) translate weak digests to sha256 first. wayback_url points at the archived bytes that actually carry the hash; DOI/arXiv/PMID identify the work; fatcat idents remain as join keys into the raw dumps.
