scope:

This specification focuses on the integration and application of heterogeneous data from urban infrastructure systems, e.g. water, transport, energy, drainage and waste, etc., so as to support smart city planning. It builds a data framework that involves possible multi-source common data through standardized data integration and sharing mechanism, which include recommendations for: - precision, dimension of the data, where at the same time raise the recommendations on data collection, update, and storing mechanism; - a data model for data integration, make suggestions on data standardization and data fusion approaches for heterogeneous smart city infrastructure data for each involved data; - a data security level and sharable attributes for each involved data, establishes principles on data sharing/exchange.
