临近空间科学探测数据的共享与实践

为促进鸿鹄专项临近空间科学探测数据资源的有效应用，为国家科学数据资源增加新的数据成员，开展临近空间科学探测数据共享相关技术研究.依据相关元数据国家标准与规范，借鉴参考多个领域科学数据元数据的构建方法，通过分析临近空间科学探测数据的数据特征，研究设计了符合临近空间科学探测数据共享需求的核心元数据模型，从不同角度描述了临近空间科学探测数据的数据特征和用户访问数据时所关心信息，并基于该模型实现了临近空间科学探测数据资源目录服务，设计了临近空间科学探测数据共享服务平台，实现了临近空间科学探测数据的归档管理和共享分发，为使用鸿鹄专项数据开展科学研究和有效应用提供了有效支撑. 

Near Space Scientific Exploratory Data Sharing Research and Practice

In order to promote the application effect of near space scientific exploratory data resources which produced by Honghu Project, and add new data members to the national science data resources, the research on data sharing. Technology of scientific exploratory data resources is developed. According to the relevant national standards of metadata and the experience of the construction methods of scientific data metadata in many related fields, by analyzing the data characteristics of near space scientific exploratory data, a core metadata model is designed to meet the needs of data sharing. The data characteristics and the information which users concern is described from different perspectives. Based on the core metadata model, the resource directory service and data sharing service platform of near space scientific exploratory data is designed and implemented. The archive management and the data shared distribution function of near space scientific exploratory is accomplished which provides an effective support for the scientific research and application with the exploratory data of Honghu project.
