CitySDK – City Service Development Kit (EU CIP). Forum Virium Helsinki (FVH) coordinates CitySDK, which compiles a toolkit for the development of digital services for cities.
The toolkit includes open and interoperable digital service interfaces as well as processes, guidelines and usability standards. CitySDK enables a more efficient utilization of the expertise and know-how of developer communities in the city service development. CitySDK aims at creating open interoperable interfaces between cities.
The project focuses on three Pilot domains: participation, mobility and tourism. Within each of the three domains, a large-scale Lead Pilot is carried out in one city and later replicated in partner cities. (
