Published field
snippet · verbatim

  1. Boletín Oficial CABA — Decreto 478/2013
Claim 4 clm-1ca0f3733b274c68 quantitative
A CKAN catalogue query on 26 July 2026 returned 451 datasets and not one unlicensed: 386 under an Argentine port of Creative Commons Attribution 2.5, 60 under an unversioned CC BY, and 5 under the CC BY 4.0
Published field

Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The licence-facet call made on 26 July 2026 returned result.count 451 with CC-BY-2.5-AR 386, cc-by 60 and CC-BY-4.0 5, summing exactly to the total.
Caveat
A live query: on 5 October 2026 the same call returned 455 datasets (386 / 64 / 5), still none unlicensed.

Claim 5 clm-51c7ca7d12db0eca descriptive
that the city's own publication guide says it always applies
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The guide: 'se aplicarán siempre Licencia Creative Commons Attribution 4.0 (CC BY 4.0) para todos sus contenidos digitales.' Its own footer, however, licenses the site under CC Reconocimiento 2.5 Argentina.
Caveat
No claim-specific caveat recorded

Claim 6 clm-ba9fd648a3043756 quantitative
416 of the 451 had been touched within the previous twelve months
Published field
snippet · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The metadata_modified query run on 26 July 2026 (window from 26 July 2025) returned 416.
Caveat
Metadata modification is a weaker test than the declared refresh frequency the city's audit office used. On 5 October 2026, 387 of 455 had been modified in the preceding twelve months.

  1. BA Data — CKAN package_search, twelve-month currency
Claim 7 clm-d5ed9d797bb8d9f2 quantitative
The city's audit office reported in 2022 that many datasets had nonetheless passed their declared refresh deadline
Published field

Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
El Auditor (16 Dec 2022) on the AGCBA report: 'el organismo de control halló que gran cantidad de los datasets tenían el plazo de la frecuencia de actualización vencido', and some data were 'desactualizados, con errores y omisiones'.

451 datasets, every one licensed and all under Creative Commons Attribution terms: 386 CC BY 2.5 Argentina, 60 unversioned CC BY, 5 CC BY 4.0 (sum exact). 416 of 451 updated within the previous twelve months — portal API, 26 July 2026.

Claim 10 clm-72cdb3d520f77a95 quantitative
A repeat call on 5 October 2026 returned 455 datasets (386 / 64 / 5), still none unlicensed, with 387 modified in the previous twelve months.

mapped · no interpretation or interpolation added by this file
What the mapping says
The licence-facet call on 5 October 2026 returned count 455 with CC-BY-2.5-AR 386, cc-by 64, CC-BY-4.0 5; a metadata_modified query for the window from 5 October 2025 returned 387.
Caveat
The twelve-month figure comes from the same API with the window moved to 5 October 2025; the listed currency URL keeps its July 2025 start date.

Claim 11 clm-145633a6c4d32f4c descriptive
A licence rule written into an operational guide instead of a decree's binding articles drifts quietly
Published field
lesson · verbatim
Mapping
mapped · no interpretation or interpolation added by this file
What the mapping says
The decree's operative articles name no licence (only the recitals say 'bajo licencia libre'); the licence rule — CC BY 4.0 'siempre' — lives in the publication guide.
Caveat
'Drifts quietly' is our reading of the gap between the guide and the catalogue.

Published field

Own call, 26 July 2026. result.count = 451; search_facets.license_id.items = CC-BY-2.5-AR 386, cc-by 60, CC-BY-4.0 5 — summing to exactly 451, so no dataset carries an empty or 'notspecified' licence. A separate /api/3/action/license_list call returned only CKAN's stock registry, so the ids CC-BY-2.5-AR and CC-BY-4.0 are local additions to this instance.

Own call, 26 July 2026: result.count = 416, i.e. 92% of the 451-dataset catalogue had metadata modified within twelve months. This is a weaker test than the audit's — a dataset declaring daily updates but last touched six months ago passes here and fails there.

Section 'Licencia de utilización de datos' states verbatim: 'se aplicarán siempre Licencia Creative Commons Attribution 4.0 (CC BY 4.0) para todos sus contenidos digitales.' The same page's footer reads 'Los contenidos de buenosaires.gob.ar están licenciados bajo Creative Commons Reconocimiento 2.5 Argentina License' — the contradiction is inside the city's own document, and the catalogue follows the footer. The guide sets no universal refresh cadence: 'La actualización de los conjuntos de datos se realiza conforme a la frecuencia establecida en cada dataset.'

Supports the lineage: Decreto 156/2012 created data.buenosaires.gob.ar 'para facilitar la búsqueda, descubrimiento y acceso' to public-sector datasets; Decreto 478/2013 established open by default. Also cites Ley 104 (access to public information, reformed by Ley 5784/2016) making open format a criterion, and Ley 1845 on personal data as the limit.

The decisive check for the licence question. Art. 1 commands publication of 'todos los datos producidos, almacenados y/o recolectados en medios digitales... cuya publicidad no se encuentre excluida por normas específicas'; art. 2 requires each ministry to file an Open Data Plan. No operative article names a licence — the phrase 'bajo licencia libre' appears only in the CONSIDERANDO, which does not bind. I did not obtain the full text of Decreto 156/2012.

Independent counterweight. Auditoría General de la Ciudad de Buenos Aires, report dated 18 October 2022, covering the portal under the DG de Calidad Institucional y Gobierno Abierto and the DG de Arquitectura de Datos. Found a large share of datasets past their declared update-frequency deadline and data 'desactualizados, con errores y omisiones en la información'; that publication requires 'acuerdos de apertura de datos entre la repartición y las áreas encargadas de la publicación' rather than automatic flows; and that most technical staff worked under service contracts, where 'la falta de formalización en la relación laboral de los agentes podría generar inestabilidad'.

Establishes today's operator: the DG de Gobernanza de Datos, under the Subsecretaría de Innovación Administrativa of the Secretaría de Innovación y Transformación Digital, maintains and administers the BA Data portal and vets datasets for publication. A 2025 end-of-tenure report for the directorate appears in the Boletín Oficial (PE-RES-MJGGC-381-25), confirming the body still existed under the current administration.

Known limits of this file
  • Publisher names and source languages have not yet been classified; domains are recorded without guessing.
  • Existing source notes are descriptive locators, not page- or paragraph-exact citations.
  • A missing archive, publication date or content hash is shown as null rather than inferred.
  • The project-level evidence grade ranks the strongest source in the entry; it is not a truth score for every claim.
