The blueprint includes the establishment of public data training hubs and the promotion of collaborative corpus development and sharing to bolster the advancement of AI applications. Simultaneously, it envisages the construction of a collaborative innovation simulation platform for smart cities, further opening up application scenarios and data resources, and catalyzing the integration and value realization of innovation resources. Moreover, it outlines the creation of a value-added collaborative network for data circulation and utilization, aiming to integrate Beijing's public data products and services into the national data market. The guidelines also emphasize leveraging the preeminent role of public data to expedite the establishment of an open, interconnected, and efficiently circulating urban trusted data space across sectors including culture, finance, healthcare, education, land and spatial planning, meteorology, and transportation.
