Implementing Geographical Information System Grid Services to Support Computational Geophysics in a Service-Oriented Environment

We describe the architecture and implementation of the Solid Earth Research Virtual Observatory (SERVO)’s Complexity Computational Environment. We base our design on a globally scalable distributed “cyber-infrastructure,” or Grid, built around a Web Services-based approach consistent with the extended Web Service Interoperability (WS-I+) model. In order to investigate problems in earthquake modeling and forecasting, we … Read more

Building Sensor Filter Grids: Information Architecture for the Data Deluge

We discuss a general architectural approach to knowledge and information management and delivery in distributed systems. Our approach is based on the recognition that time-stamped, streaming information message units form the core of seemingly disparate systems that range from online sensors and scientific instruments to Web information retrieval. Globally distributable Grid services manage these information … Read more
