Collaboration Environments – DataNet Federation Consortium

1. Collaboration Environments – DataNet Federation Consortium Communities of Practice Project Policy-based Data Management • Data Driven Science • Implement national data grid • Federate existing discipline-specific data management systems to enable national research collaborations • Enable collaborative research on shared data collections • Manage collection life cycle as the user community broadens • Integrate “live” research data into education initiatives • Enable student research participation through control policies Shared Collection Processing Pipeline Digital Library Reference Collection Federation • Turn Management Policies into computer actionable Rules • Turn Management Processes into remotely executable computer procedures • Apply a workflow at the storage system to filter, subset, manipulate data • Minimize size of data moved over the network • Automate administrative tasks • Compose procedural workflows from operations encapsulated in micro-services • Organize state information as metadata on logical name spaces for files, users, storage, rules, and policies Cyber-infrastructure Partners Community-Based Collection Life Cycle Univ. of North Carolina, Chapel Hill Univ. of California, San Diego Arizona State University Drexel University Duke University University of Arizona University of South Carolina Science and Engineering Initiatives Ocean Observatories Initiative, the iPlant Collaborative, Institute for the Environment, Cyber-Infrastructure-Based Engineering Repositories for Undergraduates, Odum Social Science Institute, Temporal Dynamics of Learning Center Workflow Management Workflow file eCWkflow.mss Directory holding all input and output files associated with workflow file (mounted collection that is linked to the workflow file) /earthCube/eCWkflow VIC Hydrology Analysis Rules eCWkflow.run Choose gauge or outlet (HIS) RHESSys workflow to develop a nested watershed parameter file (worldfile) containing a nested ecogeomorphic object framework, and full, initial system state.
