Istanbul's metropolitan municipality (İBB) launched a public open-data portal at data.ibb.gov.tr in January 2020, months into Ekrem İmamoğlu's mayoralty, as a transparency measure to surface data that had been scattered across the city's ~14 subsidiary companies. It now publishes around 550 machine-readable datasets spanning mobility, environment, governance, budget and social services, released under İBB's own open licence (compatible with CC BY 4.0) with developer API access.
