AsOf Data

Open snapshots with a DOI.

Periodic dumps of the full ledger: entities, claims, sources and the links between them, as JSONL and Parquet. Published on Hugging Face with a Zenodo DOI so papers and benchmarks can cite a fixed version.

Latest snapshot

Snapshots are produced monthly by the snapshot workflow (pipeline/snapshot.py). The first public one is published once a Hugging Face dataset is configured. Until then the live API, llms-full.txt and the markdown twins are the record.

Sources

When each source last put a new claim on the record. Structured sources refresh daily (Wikidata on Sundays); feeds every weekday.
