农业科技信息核心元数据标准框架研究及其著录信息管理系统

【目的】制定农业科技信息核心元数据标准及其扩展原则，开发基于农业科技信息核心元数据的计算机著录信息管理系统。【方法】研究都柏林核心元数据、联合国粮食及农业组织农业元数据元素集和中国科学院科学数据库核心元数据标准的制定策略及方法，以都柏林核心元数据首创计划所建议的元素作为起点,结合农业科技信息的具体特征，确定相关数据元素及扩展原则。通过对大量农业科技信息用户需求的分析，用软件工程的思想进行著录信息管理系统的开发。【结果】确定75个元数据元素，5条扩展原则和7条应用方案创建方法，开发出B/S模式的著录信息管理系统。【结论】农业科技信息核心元数据标准框架及其著录信息管理系统为农业科技信息的检索、共享、整合、交换及其他应用提供了支撑。

Primary Studies on Agricultural Scientific and Technical Information's Core Metadata(ASTICM) Register System

【Objective】Establish the Agricultural Scientific and Technical Information Core Metadata (ASTICM) standard and its expand principle, develop the register system based on ASTICM.【Method】Study the policy and methods of DC, SDBCM and AgMES, take the proposed elements of the Dublin Core Metadata Initiative (DCMI) as a starting point, to confirm the related metadata elements and the expand principle. Analyze the requirement of a great number of users of agricultural information, and develop the register system with the thought of soft engineering. 【Result】Confirm 75 metadata elements, 5 expand principles and 7 application profile creation methods, and developed a register system based on B/S mode. 【Conclusion】The ASTICM framework and its register system support the search, sharing, integration exchange and other application effectively.
