| 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. | |
