Resource Information Management in Chinese Virtual Observatory

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.
