@robotixai/lexius-fetcher

EUR-Lex CELLAR fetcher + deterministic extractor for the Lexius compliance platform. Fetches verbatim regulation text from the Publications Office and extracts typed facts (fine amounts, percentages, dates, cross-references, shall-clauses).

Quick Start

# 1. Start the database
docker run -d -p 5432:5432 \
  -e POSTGRES_PASSWORD=$POSTGRES_PASSWORD \
  -e POSTGRES_DB=$POSTGRES_DB \
  -e POSTGRES_USER=$POSTGRES_USER \
  robotixai/lexius-db
export DATABASE_URL=postgresql://$POSTGRES_USER:$POSTGRES_PASSWORD@localhost:5432/$POSTGRES_DB

# 2. Fetch EU AI Act (articles + annexes + extract facts)
npx @robotixai/lexius-fetcher ingest --celex 32024R1689 --legislation eu-ai-act

# 3. Fetch DORA
npx @robotixai/lexius-fetcher ingest --celex 32022R2554 --legislation dora

Commands

ingest — Fetch + extract in one pass

npx @robotixai/lexius-fetcher ingest \
  --celex 32024R1689 \
  --legislation eu-ai-act

Fetches verbatim XHTML from EUR-Lex CELLAR, parses articles + annexes, writes to the articles table as AUTHORITATIVE, then runs the deterministic extractor to populate article_extracts.

Options:

• --celex <id> — CELEX number (e.g., 32024R1689 for EU AI Act)
• --legislation <id> — Legislation ID in the database
• --dry-run — Parse but don't write
• --no-extract — Skip the extractor pass

extract — Run extractor on existing articles

npx @robotixai/lexius-fetcher extract --legislation eu-ai-act
npx @robotixai/lexius-fetcher extract --article eu-ai-act-art-99

backfill-derivation — Auto-populate derivedFrom

# See what would change
npx @robotixai/lexius-fetcher backfill-derivation --legislation eu-ai-act

# Apply
npx @robotixai/lexius-fetcher backfill-derivation --legislation eu-ai-act --apply

Uses article cross-reference extracts to propose derivedFrom additions on curated obligations, FAQ, and penalties.

What it extracts

| Extract type | Example | Source | |---|---|---| | fine_amount_eur | EUR 35,000,000 | Art. 99(3) | | turnover_percentage | 7% | Art. 99(3) | | date | 2 August 2026 | Art. 113 | | article_cross_ref | "referred to in Article 5" | Throughout | | annex_cross_ref | "Annex III" | Throughout | | shall_clause | "providers shall establish..." | Throughout |

All extracts are AUTHORITATIVE — deterministic regex parsing, no LLM.

Database

Requires a PostgreSQL database with the Lexius schema. Fastest setup:

docker run -d -p 5432:5432 \
  -e POSTGRES_PASSWORD=$POSTGRES_PASSWORD \
  -e POSTGRES_DB=$POSTGRES_DB \
  -e POSTGRES_USER=$POSTGRES_USER \
