The document discusses the City Service Development Kit (CitySDK), an open source platform that collects, annotates, links, and distributes city data as linked open data. The CitySDK aims to facilitate sharing best practices across cities by providing common service interfaces and guidelines. It describes several use cases where the CitySDK has helped make city data more accessible and interoperable for developers, researchers, citizens and other stakeholders. Examples of applications that have been built using CitySDK data and APIs are also mentioned.
