Abstract :
The development of web has brought rich applications and services, giving users convenience, but also causing that the user´s information is locked and isolated, the users´ resource are disperse, and the operation granularity is not uniform, which ultimately harm the end-users. This paper presents PGOS,Personal Grid Operation System, a general-purpose software for controlled sharing of cross-domain resources in personal net computing [1]. It accesses disperse resources uniformly from web client in order to connect the information islands formed by the companies, and it provides uniform fine-grained sharing mechanism, in addition, we can build new applications by combining the integrated resources in PGOS. The article proposes PGOS Core to complete decentralized user authentication, authorization and access control, Funnel is used to abstract the resource and make decentralized resource discovery, simultaneously PGSML, the Personal Grid Service Markup Language, is put forward to construct PGOS applications.
