Open Codes

Open dataset of French legal code articles with embeddings.

Chunked articles from French legal codes sourced from Legifrance via the PISTE API, with 1024-dimensional embeddings generated by Mistral AI.

Each row is a text chunk enriched with full article metadata from the parent legal code article.

Dataset Description

  • Source: PISTE Legifrance API (official French government legal database)
  • License: Licence Ouverte / Etalab 2.0
  • Embeddings: Mistral AI mistral-embed (1024 dimensions)
  • Update frequency: Daily (nightly sync at 02:00 UTC, dataset push at 06:00 UTC)
  • Codes: Dynamically sourced from LEX_codes_piste (active codes only)
  • Quality: Dedup + stale-chunk filtering applied before every push

Legal codes included

The list of legal codes is dynamic and managed in the LEX_codes_piste table. Adding a new code there (with actif=true) automatically includes it in the next sync and export.

Schema

Chunk fields

Column Type Description
chunk_text string Text content of the chunk
embedding float32[1024] Mistral AI embedding vector
id_legifrance string Legifrance article identifier
code_name string Human-readable code name (e.g. "Code civil")
chunk_index int32 Chunk position within the article (0-indexed)
start_position int32 Character offset in original article text
end_position int32 End character offset in original article text
code string Legal code identifier (e.g. LEGITEXT000006070721)
num string Article number (e.g. "L. 1234-5")
etat string Article status (VIGUEUR, ABROGE, etc.)
fullSectionsTitre string Full hierarchy path in the code

Article metadata fields (prefixed article_)

Identifiers

Column Type Description
article_id_legifrance string Legifrance article ID
article_code string Legal code ID
article_num string Article number
article_cid string Consolidated ID
article_idEli string ELI (European Legislation Identifier)
article_idEliAlias string ELI alias
article_idTexte string Text ID
article_cidTexte string Consolidated text ID

Content

Column Type Description
article_texte string Full article plain text
article_texteHtml string Full article HTML
article_nota string Article notes (plain text)
article_notaHtml string Article notes (HTML)
article_surtitre string Article subtitle
article_historique string Article history

Dates & Status

Date format: article_dateDebut and article_dateFin are stored as Unix timestamps in milliseconds (string type). This is the raw format returned by the Legifrance PISTE API.

To convert to a human-readable date in Python:

from datetime import datetime, timezone

timestamp_ms = "1301529600000"
dt = datetime.fromtimestamp(int(timestamp_ms) / 1000, tz=timezone.utc)
print(dt)  # 2011-03-31 00:00:00+00:00

Special value: 32472144000000 (year 2999) means "no end date" — the article is in force indefinitely.

Column Type Description
article_dateDebut string Effective start date (Unix ms)
article_dateFin string Effective end date (Unix ms, 32472144000000 = indefinite)
article_dateDebutExtension string Extension start date (Unix ms)
article_dateFinExtension string Extension end date (Unix ms)
article_etat string Status: VIGUEUR (in force), ABROGE (repealed), etc.
article_type_article string Article type
article_nature string Legal nature
article_origine string Origin (e.g. LEGI)
article_version_article string Version identifier
article_versionPrecedente string Previous version ID
article_multipleVersions bool Has multiple versions

Hierarchy

Column Type Description
article_sectionParentId string Parent section ID
article_sectionParentCid string Parent section consolidated ID
article_sectionParentTitre string Parent section title
article_fullSectionsTitre string Full hierarchy path
article_ordre int32 Sort order within the code
article_partie string Partie (e.g. "Partie legislative")
article_livre string Livre
article_titre string Titre
article_chapitre string Chapitre
article_section string Section
article_sous_section string Sous-section
article_paragraphe string Paragraphe

Extras

Column Type Description
article_infosComplementaires string Additional info (plain text)
article_infosComplementairesHtml string Additional info (HTML)
article_conditionDiffere string Deferred condition
article_infosRestructurationBranche string Branch restructuring info
article_infosRestructurationBrancheHtml string Branch restructuring (HTML)
article_renvoi string Cross-references
article_comporteLiensSP bool Contains SP links
article_idTechInjection string Technical injection ID
article_refInjection string Injection reference
article_numeroBo string BO number
article_inap string INAP code

Usage

from datasets import load_dataset
from datetime import datetime, timezone

ds = load_dataset("ArthurSrz/open_codes", split="train")

# Access a chunk with its embedding and article metadata
row = ds[0]
print(row["code_name"])                # e.g. "Code civil"
print(row["chunk_text"][:200])
print(len(row["embedding"]))           # 1024

# Convert dates from Unix ms to datetime
date_debut = datetime.fromtimestamp(int(row["article_dateDebut"]) / 1000, tz=timezone.utc)
print(date_debut)                      # e.g. 2011-03-31 00:00:00+00:00

# Filter by legal code
code_civil = ds.filter(lambda x: x["code_name"] == "Code civil")

# Filter active articles only
en_vigueur = ds.filter(lambda x: x["article_etat"] == "VIGUEUR")

# Use embeddings for semantic search
import numpy as np
query_emb = np.array(ds[0]["embedding"])

Provenance

Built by the marIAnne project. Sync pipeline fetches articles nightly from PISTE Legifrance, chunks them, and generates embeddings via Mistral AI.
