摘要
信息技术的高速发展正在逐步影响着传统的科学研究领域,虚拟天文台(VO)就是其中的一个典型代表。它与当前最前沿的网格技术结合起来,以实现全球天文资源的共享,充分挖掘海量天文数据的科学潜能。在中国虚拟天文台的设计与实现过程中,我们采取了开放网格服务架构(OGSA)的体系结构,以服务的方式来组织和管理虚拟天文台中的资源。中国虚拟天文台资源管理系统的设计实现,资源信息的注册及发现是一个关键的问题,直接影响着整个系统的运行。本文以OGSA为基础,结合Globus Toolkit 3(GT3)的具体实现,阐述中国虚拟天文台资源信息管理系统的设计与实现。
Information technology has been affecting on all fields of traditional scientific research deeply. Virtual Observatory is a typical example of combination of the latest information technologies with astronomy. Taking advantages of advanced information technologies, for example, Grid technology, it aims to achieve the seamless and global access to astronomical information and maximum scientific output of huge modern astronomic datasets. In the process of design and implementation of resource information system for Chinese Virtual Observatory, we adopt Open Grid Service Architecture （OGSA） as its infrastructure, and all resources are managed in the system as services. Resource management, especially resource registry and discovery is a key consideration for both Grid and Virtual Observatory, which affects directly on the performance of the whole system. Based on OGSA and the one of its implementations, GT3, this paper describes the design and implementation of resource information management system in Chinese Virtual Observatory.
