On Design of Agricultural Semantic Grid Portal and Implementation

We analyses the state of the art and the research challenges that are involved in developing the computing infrastructure needed for e-Science in agricultural semantic grid portal. In so doing, a conceptual architecture for the agricultural semantic grid is presented. This architecture adopts a service-oriented perspective in which distinct stakeholders in the agricultural process provide services to one another in various forms of marketplace. The view presented in the paper is holistic, considering the requirements of e-agriculture and the agricultural expert at the data/computation, information and knowledge layers. The data, computation and information aspects are discussed from a distributed systems viewpoint and in the particular context of the Web as an established large scale infrastructure. These techniques are shown to be the key to working with heterogeneous information and also to working with experts and establishing communities of e-scientist s in agriculture
