In this paper, we propose an information service component of Moredream which we refer to as GAIS, for providing advanced functionalities and more plentiful resource information in order to satisfy the requirements for the various applications in the K*Grid computing environment characterized by both high performance and high throughput computing. In particular, GAIS includes interfaces and functionalities for the dynamic VO management, universal VO discovery, service categorization and efficient information providers. Consequently, we anticipate that our Grid information service will be broadly utilized through the improved service qualities.
