Open Codes

Open dataset of French legal code articles with embeddings.

Chunked articles from 5 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)
• Rows: ~1,630 chunks from ~1,630 articles

Legal codes included

Code ID	Name

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

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)

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article_etat	string	Status: VIGUEUR (in force), ABROGE (repealed), etc.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

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.
