Abstract
The World Data System (WDS) plays an important role in promoting global scientific data management, exchange, and sharing. There are 8 WDS data centers in mainland China including study areas of astronomy, space science, global change, renewable resources and environmental, cold and dry regions, microbiology, geophysics, and the ocean. This paper summarizes the current status of the WDS China data centers, along with their major progress in recent years. This progress includes a clearinghouse for metadata exchange, research data archival, historical data saving, international data exchange, data publishing models, CoreTrustSeal certification, open repositories for the scientific community, science popularization services, international training workshops, and awards. We conclude with a discussion of the opportunities and challenges faced by WDS China data centers.
