This standard defines a process to discover smart city component systems deployed in the city and proposes a classification mechanism to describe the component system based on the resources and data elements it exposes (such as Internet of Things (IOT) system, E-Government system, Geo-spatial system, Collaboration system, or similar component systems.) This standard defines a common identity scheme for entities (such as assets, things, spaces, service providers and people) and the data exchange format and interfaces for each class to be followed across similar component systems deployed in a city. The standard also describes the city command center, its role in setting intents (operational goals and constraints) and the mechanism to propagate the intent across the component systems.
