Spanish State and Autonomous Community Law Corpus (BOE)

Research snapshot of Spanish state (estatal) legislation plus consolidated legislation of the autonomous communities (legislación consolidada autonómica), collected from the Boletín Oficial del Estado (BOE) open-data API.

Not legal advice. The official gazettes prevail over this corpus. This snapshot is not the official consolidada: every text is a texto consolidado de carácter meramente informativo.

Contents

• data/laws.parquet — one row per instrument. State rows come first and are unchanged; autonomous-community rows are appended ordered by jurisdiction, then date_issued, then BOE identifier.
• data/articles.parquet — text blocks (artículos, disposiciones, preámbulo, firma, anexos, headings), one row per current consolidated block.
• scrapers/ — collectors used to build this snapshot.
• PACK_META.json — build/append metadata and never-thin check results.

Autonomous-community rows use id = '<ES-CCAA>-<BOE identifier>' (e.g. ES-CT-BOE-A-1997-9499), so they cannot collide with the state rows (whose id is the bare BOE identifier); official_identifier keeps the bare BOE/regional-gazette identifier and metadata_json.metadata adds jurisdiction_iso_3166_2, departamento_codigo, ambito_codigo and rango_codigo. Article ids are <law id>/<BOE block id>. Row construction (law text with the informative notice, current version of each block, law_status from estatus_derogacion / vigencia_agotada) is identical to the state rows.

License / reuse

Only one source is used for every row: the AEBOE (Agencia Estatal Boletín Oficial del Estado) open-data API. Reuse follows the AEBOE general reuse conditions (licencia tipo, Resolución de 27 de junio de 2024, in force since 28 June 2024), https://www.boe.es/informacion/aviso_legal/index.php :

• commercial and non-commercial reuse is permitted (copy, distribute, modify, combine, create derived products);
• cite the source with a link to https://www.boe.es — "Fuente de los datos: Agencia Estatal Boletín Oficial del Estado" for copies, or "Basado en datos de la Agencia Estatal Boletín Oficial del Estado" for modified/derived works;
• do not distort the meaning; do not suggest official character — each consolidated text must state that it is a texto consolidado de carácter meramente informativo (every text in laws.parquet starts with that notice);
• do not suggest AEBOE participation, sponsorship or endorsement; mention the last-update date (kept in metadata_json.metadata.fecha_actualizacion); identify modifications as such; keep the update-date and reuse-condition metadata;
• respect GDPR / LOPDGDD for any personal data.

Autonomous-community portals and gazettes: none were used (no CCAA portal terms therefore apply to this dataset). The texts of autonomous-community laws reproduced here are BOE's informative consolidations; the authentic text is the one published in each community's official gazette (BOJA, BOA, BOPA, BOIB, BOC, BOC(antabria), BOCYL, DOCM, DOGC, DOE, DOG, BOCM, BORM, BON, BOPV, BOR, DOGV), which determines legal effect (see the AEBOE notice that BOE consolidations of autonomic laws are prepared after BOE publication, which always follows publication in the regional gazette).

This dataset is not legal advice. The official gazettes prevail.

Known limitations

• Scope = BOE consolidated autonómico only. BOE consolidates the main autonomous-community norms with rank of law (leyes, leyes forales, decretos legislativos, decretos-leyes, plus a few resoluciones/acuerdos): 3,620 instruments listed by the API under ambito@codigo:2, all collected. Autonomous-community regulations (decretos, órdenes) are not consolidated by BOE and are not included. Not every regional law has a BOE consolidated version: by Ley/Ley Foral numbering, BOE consolidates 49.6% of numbered regional laws in the years it covers (3,212 numbered laws missing from sequences; lower-bound estimate). Many of the unconsolidated numbers are expected to be amending, budget (presupuestos) and accompanying-measures laws whose provisions are already merged into the consolidated texts of the laws they amend, so this is not a measure of missing in-force content; laws not consolidated by BOE would have to come from the official CCAA portals (not used in this snapshot).

• Coverage gap table (offline estimate from Ley / Ley Foral numbering N/YYYY per community and year among BOE-consolidated laws; "missing in sequence" = numbers in 1..max(N) with no BOE consolidated version; lower bound, and many are amending/budget laws already merged into consolidated texts):

  jurisdiction	Consolidated numbered laws	Est. missing in sequence	Est. coverage
  ES-AN	183	127	59.0%
  ES-AR	214	182	54.0%
  ES-AS	135	93	59.2%
  ES-IB	219	157	58.2%
  ES-CN	175	130	57.4%
  ES-CB	151	122	55.3%
  ES-CL	175	128	57.8%
  ES-CM	157	143	52.3%
  ES-CT	284	411	40.9%
  ES-EX	157	98	61.6%
  ES-GA	210	203	50.8%

  ES-PV	185	198	48.3%
  ES-RI	139	82	62.9%

  ES-CE / ES-ML	0	—	n/a (no legislative power)

• BOE consolidations of autonomic norms only reflect amendments made by norms with rank of law (not by regional regulations), only express (not tacit) amendments/repeals, and are prepared after the amendment appears in BOE, so they can lag the regional gazette. estado_consolidacion = 'Desactualizado' marks texts whose newest amendment is still being incorporated (153 autonomic texts at collection time).

• Ceuta (ES-CE) and Melilla (ES-ML): 0 rows. They are autonomous cities without legislative power (no regional laws); BOE's consolidated autonómico set contains no instrument for them. Their Statutes of Autonomy (Ley Orgánica 1/1995 and 2/1995) are state organic laws and are already present as ES rows, as are all other Statutes of Autonomy and their reforms.

• Spanish only. Texts are BOE's Spanish versions; co-official-language versions (català/valencià, galego, euskara, aranés) are not included.

• Dedupe vs state rows: 0 overlap — none of the autonomic identifiers, ELIs or titles exist among the state rows, so nothing was double-inserted.

• Historical/repealed texts are included (as for the state rows) and flagged by law_status (current / repealed / historical = vigencia agotada); filter on law_status == 'current' for in-force law.

• 0 autonomic laws have 0 blocks; 0 have under 200 characters of body text after the informative notice (see country-law-triage checks).

• 245 autonomic instruments are keyed by regional-gazette identifiers (e.g. BOJA-b-…, DOGC-f-…, BOIB-i-…) rather than BOE-A-…, because BOE consolidates them from the regional publication; exactly these 245 have no ELI in the BOE metadata (eli is null).

• No duplicate ids: 0 duplicate law or article ids before or after the append (0 pre-existing article-id duplicates in the state rows; 0 new). Block ids are BOE's own (a1, dtprimera, a9-4 for articles inside annexed texts, …).

• 5 autonomic block rows have empty text (BOE block with an empty current version), as with the 3 such rows among the state rows.
