[Purpose/significance] The overall architecture of the smart elderly care data resource system has been pro⁃posed and it provided a theoretical framework and directional guidance for building a smart elderly care data resource system. [Method/process] According to the overall architecture concept, it clarified the vision and goals of the smart elderly care data resource system and built the basic framework for the system based on information ecology theory. It explored the key points and interrelationships of the four elements, including the diversified subject relationships, the process of data elementization, the application scenarios of data service, and the overall process integration guarantee.[Result/conclusion] The smart elderly care data resource system is a data ecosystem guided by the Healthy China strat⁃egy and the Digital China strategy, consisting of four elements: muti-agent, data resources, service applications, and in⁃tegrated security. It identified the problems that exist in various elements in practice through investigation, and pro⁃posed that the construction of smart elderly care data resource system should focus on the following four aspects, includ⁃ing: supply and demand matching based on multi-agent collaboration, data resources-based construction of elderly care data, value mining of application scenarios and services, and integrated system construction of elder data resourc⁃es.
