摘要
针对应急处置信息资源特点,结合信息资源发现定位、查询检索、交换共享功能需求,提出了应急处置信息资源基础和扩展元数据描述规范。基于元数据描述模型,分析了元数据服务系统主要功能,设计了元数据服务系统总体架构,对系统实现的服务架构、规范协议等关键技术进行说明,为实现信息资源的共享交换、抽取分发、集成应用提供支持。
According to the characteristics of emergency information resource, this paper analyses the function requirements of finding, positioning, query, retrieval, exchange and sharing, and proposes description standards for general metadata and extend metadata. Based on the metadata model, it analyzes the main functions of metadata service system, designs the architecture of the system, and explains the key technologies such as service distributing, data integration and so on.
