一种信息网格主体空间模型及其应用

Space model of information grid subject and its applications

相对于已有的客体空间模型研究,提出一种信息网格主体EVP空间模型,从用户的全生命周期过程(包括注册、登录、使用、维护、挂起、重新接入、退出、注销等)出发,研究了用户使用网格的各个阶段,分析了该主体模型在用户全生命周期各个阶段的变化,简述了该模型在某所信息网格中的应用,试图通过该模型分析和解决信息网格中用户的分布和异构以及用户标识的全网格统一问题。

An EVP space model of information grid subject was proposed in this paper according to the research on object space model. Using the theory of user's full life cycle (includes register, log on, use, maintenance, hang up, reconnect, exit, and log out), the processes of the grid users were studied; the change of this model during the different processes of the user's full life cycle was analyed; the applications of this model in the project of VEGA-IG were introduced, to solve the problems of information grid users, such as distributing, heterogeneous and uniform identification were tried.
