Response Decision

Much work is under way within the Grid technology community on issues associated with the development of services to foster collaboration via the integration and exploitation of multiple autonomous, distributed data sources through a seamless and flexible virtualized interface. However, several obstacles arise in the design and implementation of such services. A notable obstacle, namely how clients within a data Grid environment can be kept automatically informed of the latest and relevant changes about data entered/committed in single or multiple autonomous distributed datasets is identified. The view is that keeping interested users informed of relevant changes occurring across their domain of interest will enlarge their decision-making space which in turn will increase the opportunities for a more informed decision to be encountered. With this in mind, the chapter goes on to describe in detail the model architecture and its implementation to keep interested users informed automatically about relevant up-to-date data.

With the development of WebGIS, it plays a more and more important role in government and enterprises. The effective way to access and control spatial data, because of relating to the security and business secrets of government and enterprises, becomes an urgent concern for them. Now, RBAC (Role Based Access Control) can be a valid method to access and control uniform resource, but it is lack of flexibility and real-time ability to control spatial data in WebGIS. For that, this paper proposes G-RBAC model based on RBAC model to enhance the flexibility and real-time ability to access spatial data.
