# Provenance, personal data and the AI Act

> Arieta Data is compiled from official public-sector publications through a read-only export pipeline. Every record names its source and licence; withdrawn documents are tombstoned; raw upstream HTML is never shipped. Licences are documented per source.

- Formats: Apache Parquet, JSON Lines (gzip)
- Snapshot files: MANIFEST.json (Record counts, SHA-256 per shard, snapshot time and schema version.); DATASHEET.md (Datasheet for Datasets / Hugging Face style data card for the snapshot.); LICENCES.md (Attribution text per upstream source, generated from the lane manifests.); tombstones/ (Ids withdrawn since the previous snapshot; buyers must delete them.)
- National case law is delivered with personal data masked.
- Withdrawals become tombstones in the monthly delta; licensees must delete tombstoned records.
- No certifications are claimed.

Collection: Arieta Labs collected the upstream data through publishers' documented APIs, open-data dumps and official websites. Documents that a source lists for removal (for example takedowns listed in robots.txt) and documents withdrawn by the source are removed and delivered as tombstones. A per-source record of terms and access channels is supplied with each snapshot.

Personal data: national court decisions are not in this snapshot’s files; they are delivered separately, only after personal-data masking. CJEU case law is included as published by the Court. Documents withdrawn by their source are delivered as tombstones and deleted by the licensee.

Copyright and reuse: each record carries its source, licence and attribution. Reuse of EUR-Lex content is permitted under the EUR-Lex legal notice (Commission reuse policy, Decision 2011/833/EU); CJEU case law under the CURIA copyright notice; national texts under the terms listed per source. UK case law is not included: the Open Justice Licence does not cover computational analysis.
