    Snapshot 2026-11: launch

    The first Arieta Data snapshot, 2026-11, launches three datasets cut from the LexAPI corpus:

    • Corpus: article-level text and metadata for EU legislation, CJEU case law and national legislation.
    • History: every content-hash version observed since each document entered the corpus.
    • Graph: typed citation edges (reference, amendment, repeal, corrigendum, implementation, legal basis, proposal, transposition) with their origin.

    Scope decisions in this snapshot:

    • National case law is included, delivered with personal data masked.
    • UK case law is not offered: the Open Justice Licence does not cover computational analysis, and the separate licence from The National Archives cannot be passed on.
    • Italian Corte costituzionale decisions (CC BY-SA 3.0) are national case law, delivered masked; they are kept apart as a separate CC BY-SA file, never inside the main shards.
    • Raw upstream HTML is not included in any product.

    Each snapshot ships MANIFEST.json (counts and SHA-256 per shard), DATASHEET.md and LICENCES.md. Monthly delta snapshots with upserts and tombstones follow. Eval sets and custom cuts per jurisdiction, language, date range or document type are prepared on request.

    Counts for this snapshot are on the coverage and datasets pages.
