Currently there is no practical standard for grid middleware, most of the grid platforms are built by their own, and it's not easy to interoperate these grid platforms. Information service is one of the key components of the service oriented grid system, and information service interoperation among heterogeneous grids is the first step towards grid interoperation. Existing grid interoperability projects mainly focus on immediate bridge mechanisms, which is intricate and of poor scalability. To address the issues, a Uniform Information Service Interoperation Framework (UISIF) is proposed in the paper, which is based on the idea of mediated bridge mechanisms, and adopts virtual layer and plug-in technology.
