OGSA-DAI4.0在科学数据共享平台中的应用

摘要

介绍科学数据的特点和信息孤立现象产生的原因与现状,并通过研究OGSA-DAI项目的框架结构与原理,分析了根据其构建科学数据共享平台的可行性.最后提出以OGSA-DAI+Globus(Open Grid Services Architecture-Data Access And Integration)数据网格环境为基础,构建安全的、跨地域、跨平台的科学数据共享平台的解决方案.%The paper introduces scientific data characteristics as well as forming reasons and circumstances of information isolation phenomenon. In addition, through studying OGSA-DAI project framework architecture and principles, the feasibility of building a scientific data sharing platform upon it is analyzed. Finally, a solution is proposed to construct a secure, cross-regional and cross-platform scientific data sharing platform based on OCSA-DAI plus a Globus data grid environment.
