IEC SRD 63233-1:2022 The smart city standards inventory and mapping project was initiated to provide a systematic approach to retrieve and map the standards of smart cities on smart city reference architectures, models or frameworks and provide fundamental support for the collaborative work of standard-setters and users. Standards maps are the practical base for helping SDOs and users to identify directly and instantly the standards that are needed for any aspects of smart cities (citizen services, city infrastructure, governance, etc.). Standards maps also help in identifying the standardization gap in the ecosystem.
