  1. NetKarma : Capture and Representation of Provenance for GENI Experiments Collection Sources Collection and Represention • We collect provenance from multiple sources to obtain information describing GENI experiments and conditions of experiment including: • Experimental tool commands • Topology created using the control frameworks • Operational status on substrate /infrastructure • Code and data contained in the experimental slice • Measurement data obtained • Annotations by experimenters Log files Rule file GENI Provenance Adaptor Notifications Provenance Repository Karma Service Building Experiment Provenance Experiment Provenance Nodes Raven Distribute Package Experiment Repository Application output Run Application Gush Web browsing Agent Collection URNs Planetlab Web Interface Allocate Nodes Allocate Topology Emulab Experiment Repository Packet capture link Wisc-Measurement Measurement Set GENI Experiment Life Cycle • Karma is a workflow provenance collection tool developed by Indiana University which captures and stores process and data provenance. The framework is based on generating discrete provenance activities during the lifecycle of a “workflow” execution that can be aggregated to form complex data and process provenance graphs that can span across workflows. • GENI Adaptor provides an interface that uses the GENI experiment logs and a set of rules to derive provenance information and maps them into the Karma repository. • The adaptor is a generic log processing unit for GENI log files which comprise of two sub-units: • Log Parser • Notification Generator The diagram above shows the GENI Experiment life cycle [3] whereas the diagram below shows an OPM representation of the provenance graph for a GENI experiment. • References • Simmhan, Y.L., Plale, B., and Gannon, D., Karma2: Provenance Management for Data-Driven Workflows, International Journal of Web Services Research, 5(2): 1-22, 2008. • The Open Provenance Model (v1.01), http://eprints.ecs.soton.ac.uk/16148/1/opm-v1.01.pdf. • Lifecycle of a GENI Experiment .
