NGG: A Service-Oriented Application Grid Architecture for National Geological Survey
نویسندگان
چکیده
National geological survey works have characteristics of data enormousness, computing denseness, resource distribution, and applications heterogeneousness. As innovative information infrastructure and service architecture, grid can meet geological survey application requirements by implementing sharing and cooperation of distributed and heterogeneous resources. Based on grid technologies and OGSA, National Geological Grid (NGG), a novel service-oriented architecture with seven levels from information acquiring, processing to applying, is proposed. Some key technologies of NGG are discussed in detail, such as service chain, geological semantic sharing, and so on. A new service chain model (named Service/Resource net) based on Petri net and graph theory is presented. And NGG ontology is introduced to implement geological semantic sharing.

Spatial Information Grid and Its Application in Geological Survey
With the increasing application requirements of spatial information, traditional spatial information techniques can not solve current application problems. As novel technologies that can implement sharing of enormous distributed resource, Grid and Web services provide an effective and efficient way to share and integrate spatial information on the web. Hence, an innovate framework, i.e. Spatial...
متن کاملFine-Grained Continuous Usage Control of Service Based Grids - The GridTrust Approach
Access control techniques designed for single domain infrastructures, where users are known by domain administrators, provide considerable liberty in the usage of resources. This paradigm is not suitable for highly scalable and decentralised systems such as Grids and service oriented architectures (SOA), where resources are shared between domains, and users come from remote domains. One approac...
متن کاملDevelopment of a framework to evaluate service-oriented architecture governance using COBIT approach
Nowadays organizations require an effective governance framework for their service-oriented architecture (SOA) in order to enable them to use a framework to evaluate their current state governance and determine the governance requirements, and then to offer a suitable model for their governance. Various frameworks have been developed to evaluate the SOA governance. In this paper, a brief introd...
متن کاملTowards a Domain Specific Application Development Environment for the ELeGI architecture: the Software Factories approach
The Next Generation Grids (NGG) expert group has pioneered the vision of “Invisible Grid” whereby the complexity of Grid systems and architectures is hidden to both developers and users. In this new vision, the Grid has a different role: it will not more provide a virtual computing environment but it will be the basis of a more complex service oriented, knowledge-based and collaborative environ...
متن کاملSecurity and Trust Management for Virtual Organisations: GridTrust Approach
The GridTrust Security Framework (GSF) offers security and trust management for the next generation Grids (NGG). It follows a vertical approach for Grid security from requirements level right down to application and middleware levels. New access control models for collaborative computing, such as the usage control model (UCON), are implemented for securing the Grid systems. The GSF is composed ...
