Vision for VRV: A Computational Infrastructure • MORE than just archiving…. • data sharing, Vision for VRV: A Computational Infrastructure • MORE than just archiving…. • data sharing, tool composition, and model coupling – physical observations (traditional data) – text attributes, video and graphics – programs, models, tools, and scripts for computational processing • New data and metadata, format conversion • Web interface for distributed computing

Good Fit to NSF ITR • Computer science clearly needed – Improvements to current Good Fit to NSF ITR • Computer science clearly needed – Improvements to current technologies • Interdisciplinary, multi-institutional team, history of collaboration • EPR yes, but other sites (e. g. , Galapagos) and types of environmental data as well • Human resource development (undergrads, VRV-ET, “Saturday Academy”) • research plan "compelling" but obviously too ambitious!

Three Components (Solutions) 1 - Data Sharing • GIS, RDBMS, computational experiment management system Three Components (Solutions) 1 - Data Sharing • GIS, RDBMS, computational experiment management system (Vi. NE) are all needed • Non-spatial data and text metadata • Computational experimentation • More than physical access to files – More than flat files and simple tables

Expected Outcomes Integrating data with metadata, tools and models - A (possibly virtual) database Expected Outcomes Integrating data with metadata, tools and models - A (possibly virtual) database - Tools to visualize data (GIS and Mat. Lab) - Tools for Steering & Coupling - Publish models - Compose tools - Support migration paths for model coupling • Apply all to VRV for EPR • Educational Outreach -- VRV ET – UOregon, Portland Sat. Academy, Evergreen, etc.

Methods for Model Coupling Express model couplings so they can be implemented as coupling Methods for Model Coupling Express model couplings so they can be implemented as coupling between simulations. • Use simulation code analysis and theoretical tools such as Petri Nets to express these couplings. • Describe models so that the coupling can be automated and model descriptions can be reused. •
