摘要

While Grid services introduce efficiency in addressing the changing and often large resource demands of Grid applications, making the system context-aware takes the approach a step further by incorporating the important aspects of customisation and personalisation into Open Grid Services Architecture (OGSA) services. This is achieved by extending the concept of virtual organisations (VO) to Grid context, which link context information to users, policies and resources. Context is defined as any information that can be used to characterise the situation of an entity. When this information is modelled and properly managed, the OGSA services can become context-aware and context-aware services can be offered by the Grid.
