Goiânia runs a CKAN open-data portal at dadosabertos.goiania.go.gov.br carrying 29 datasets, every one published by the Prefeitura Municipal de Goiânia and every one under the same licence, Creative Commons Atribuição — a uniformity most municipal catalogues never manage. Most of the holdings are cadastral GIS: streets, blocks, lots, kerbs, cadastral sectors, bridges, listed heritage, sustainable-use areas and altimetry, each offered as CSV, JSON, SHP and KMZ with a PDF data dictionary. The oldest datasets were created in June 2018. Sorted by the portal's own last-modified date, the newest change to anything in the catalogue is the dengue-control file, updated on 6 April 2020; the street register was last touched in September 2018 and the economic-activity register in November 2018.

🎓 Lesson

A single uniform licence across an entire catalogue is rarer than it sounds, and Goiânia has one — but a licence governs reuse, not maintenance. The portal is online, correctly labelled and machine-readable while its most recent file is six years old, which is exactly the failure a licence audit cannot see. The city's separate fiscal-transparency portal is current and offers its own API, so the gap is in publishing the city's own operational and geographic data, not in transparency infrastructure as such.

↗ Portal de Dados Abertos da Prefeitura de GoiâniaThe portal itself — CKAN ('Impulsionado por CKAN'), 29 datasets, one publishing organisation, nine groups
↗ Portal de Dados Abertos — dataset list sorted by last modificationLoad-bearing check for the freeze: sorting newest-first puts Dengue at the top, i.e. nothing in the catalogue has been modified since that file. Also confirms the 29-dataset count and the uniform Creative Commons Atribuição licence
↗ Portal de Dados Abertos — Dengue dataset pageCreated 06/04/2020 17:05, last updated 06/04/2020 17:33; licence 'Creative Commons Atribuição'; CSV, JSON, KMZ, SHP plus PDF dictionary
↗ Portal de Dados Abertos — Logradouros dataset pageCreated 11/06/2018, last updated 18/09/2018 — the oldest creation date checked, and evidence the portal was already running in mid-2018
↗ Prefeitura de Goiânia — Acesso Automatizado aos Dados Abertos (API), portal de transparênciaThe separate, current fiscal-transparency portal with automated API access in open machine-readable formats under the Lei de Acesso à Informação. Returned 403 to automated fetching; existence and purpose verified via search results — the editor should confirm before publication
