| Abstract: | Combined with the current status of Antarctic data management and the characteristics of polar science data resulted from Chinese Antarctic and Arctic Research Expeditions, the Chinese Polar Science Database System(CPSDS) has been designed and established in 2002. The infrastructure, technical standard, mechanism of sharing data of this system are reviewed in this article. Meanwhile, the development of Chinese polar data management is summarized. As the metadata is the powerful and useful tool for managing and disseminating scientific data, the metadata is also used as “search engine” of CPSDS. Besides, the trend of data management and sharing is also discussed. |
