随着开放网格服务体系结构（OGSA）的出现，服务网格被认为是计算网格的自然发展。由于应用的多样性和复杂性，服务网格平台的研究面临着巨大的挑战。目前流行的信息服务系统基本上都是为计算资源、数据资源和网络资源提供注册、发布和管理。然而，这样的系统已经不能满足服务网格的需求。提出了一种面向服务管理和组织的信息服务模型--HowU信息服务。服务是信息发布的基本单位。该模型提供了一种新的服务命名和元数据描述机制。网格用户关心的不是服务的资源细节，而是它的存在和当前的服务能力。本文主要研究HowU信息服务的信息一致性问题，即如何保证服务在广域内的存在性和服务信息在组织域内的有效性。
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.
