随着 Internet 中数据信息量迅速增加，专业领域内的数据共享逐渐成为一个重要研究
领域，该文首先对地震网络数据分布的特殊性进行了概括，分析国外典型数据共享项目
OGSA-DAI 的特点，针对其存在以Web Service 作为接口而不便于应用开发等不足，提出建立面向应用的地震网络数据共享平台的需求和目标，文中阐述了共享平台的架构设计和主要模块的功能，对该平台实现的关键技术虚拟目录的建立和虚拟中心数据库做了详细介绍。
关键字 异构；分布；数据共享；数据虚拟目录
Abstract With fast increasing of data on Internet, data sharing in specific filed is becoming a
hotspot. In this paper, we summarize characteristics existed in seismologic network. Then analyze typical data sharing project OGSA-DAI and found its inconveniences to application development. Put forward aims of application oriented data sharing platform in seismologic network. After that, the architecture of the platform and functions of main modules is described. Also details the key technologies of the platform, such as ways to create virtual category and virtual center database.
Key words Heterogeneous, Distributed, Data sharing, Virtual category
