Abstract: As the emergence of Open Grid Service Architecture (OGSA), service grid is seen as a natural progression from computational grid. Because of the diversity and the complexity of the applications, it is a great challenge for the research of service grid platform. Currently, the popular information service systems are basically used to provide registry, publication, and management for computing resources, data resources, and network resources. However, such systems could not meet the requirement of service grid. An information service model, HowU information service, is proposed for service management and organisation. The service is regarded as the basic unit of information publication. A novel service naming and meta-data description mechanism is provided in this model. A grid user is not concerned with the resource details of a service, but its existence and current serving capability. In this paper, focus is on the information consistency of HowU information service about how to guarantee service existence in wide area and service information validity in organisation area.

Keywords: grid computing; information services; index services; serving capability; information consistency; service state; service interaction; open grid service architecture; OGSA; grid services; service management; service organisation; service guarantees; information validity.
