【摘要】 科学数据共享在促进科学发展过程中具有重要意义。综合性科学数据中心要对多元化的科学数据提供服务,保护数据提供者的权益,也要保证数据的可获取性。回顾了科学数据共享的发展现状,针对综合性科学数据中心,将科学数据作为一种虚拟商品对待,利用B2C概念构建综合性科学数据共享系统,基于数据用户、数据提供者、数据中心3类用户实现了对应的功能。从科学数据的描述、发布、发现、流通以及评价5个方面对科学数据共享系统的关键问题进行了讨论。以中国西部环境与生态科学数据中心为应用实例,介绍了基于B2C架构的科学数据共享系统的应用方法。更多还原

【Abstract】 Data sharing could play an important role in the promotion of science development.Comprehensive scientific datasets should be serviced in the composite scientific data center.The rights of scientific data providers should be protected as the availability of the datasets,and should be guaranteed in the composite scientific data center.The current development of the scientific data sharing was reviewed,then a B2Cpattern based data sharing system for composite scientific data center is designed which treats is treated scientific datasets as a kind of virtual commodity,and the functionalities of users,data providers and the manager of data center are also implemented.The key issues in scientific data sharing are discussed from five aspects:the description of scientific datasets,the release of scientific datasets,the discovery of scientific datasets,the circulation of scientific datasets and the evaluation of scientific datasets.As a case study,the environmental and ecological science data center for west China use the B2Cpattern based data sharing system to service its users with good achievements.更多还原
