How this atlas is made · What “last verified” means

Ankara Metropolitan Municipality opened seffaf.ankara.bel.tr on 28 July 2022 as a map-first open data portal, organised around a GIS viewer rather than a dataset table. It publishes municipal excavation sites, transit boarding counts, Başkent Kart distribution and spending figures, reservoir levels, social assistance payments by district and the incoming, pending and completed application counts of the Başkent 153 request line. The licence is the city's own instrument, the "Ankara Büyükşehir Belediyesi Şeffaf Ankara Açık Veri Lisansı", version 1.0.

🎓 Lesson

A bespoke wrapper around a standard licence can quietly take back what the standard licence grants. Ankara's text names CC BY 4.0 — the same unmodified international licence Montreal uses — and permits commercial reuse with attribution. But it then reserves the right to publish new versions and states that continued use means acceptance of them, while CC BY 4.0's own grant is irrevocable and cannot be re-versioned against an existing user. Read the wrapper, not just the badge.

↗ Ankara Büyükşehir Belediyesi (operator) — launch announcement, 28 July 2022Dates the launch and carries the city's own size claim: "1000'den fazla açık veri dosyası ve 300 binden fazla haritada konumlandırılmış verisi" — over 1,000 data files in 7 categories and over 300,000 map-located data points in 16 categories. Also the source of the superlative "Dünya'da indirilebilir harita tabanlı ilk ve tek açık veri platformu", quoted here as the mayor's claim, not adopted. Lists the published domains including Başkent 153 application counts and Başkent Kart spending data.

↗ Şeffaf Ankara (operator) — the portalLive portal, checked directly. Datasets are grouped in eight categories (Başkent Kart, Kültür Sanat ve Spor, Ulaşım, Çevre ve Sağlık, Toplum, Eğitim, Bilim ve Teknoloji, Genel) per resources/data/TeoAbbAcikVeri.json. The dataset list itself is served from an internal table (teo_abb_acik_veri) through an encrypted application endpoint rather than a public catalogue API, so the file count could NOT be verified independently and remains the city's own figure.
