 # BOE and BORME Open Data
 
-This repository contains a reproducible, resumable and append-only pipeline for the open data published by the Spanish Agencia Estatal Boletin Oficial del Estado (AEBOE). It collects the complete published history exposed by the AEBOE Open Data API: the daily summaries (sumarios) of the Boletin Oficial del Estado (BOE) and the Boletin Oficial del Registro Mercantil (BORME), the consolidated legislation catalogue with full consolidated texts, and the auxiliary reference tables.

+## Coverage notice
+
+This is not a complete documentary archive of the BOE or BORME. Gazette sumario rows contain index metadata and document URLs, not the full body of every gazette document or commercial registry announcement. Full-text content is provided for consolidated legislation in `boe_legislacion_texto`; this does not cover all published gazette documents. Historical coverage is limited to the sources and dates acquired for this release, not every year or every AEBOE collection. The separate 2023–2025 archival pilot is incomplete and is not included in this published dataset.
 
 
 The data is observational and legal in nature and has no target label or predefined classes. Every configuration is provided as a single `train` split containing the complete table. Artificial train, validation and test partitions would imply a prediction task that the source does not define.

 ## Limitations
 
-The BOE Open Data API exposes the gazette summaries and the consolidated legislation. This dataset reproduces everything the API exposes, including the document URLs, but it does not mirror the body of every historical gazette document. Consolidated norms can be revised by the publisher; the pipeline records each observed version rather than assuming the current text is definitive. Auxiliary and catalogue endpoints can change over time, so later snapshots can add or restate values. This is a research dataset and is not legal advice; the official and authentic texts are the signed PDFs published by the AEBOE.
