    2323The third hands-on portion of the tutorial showed participants how they can easily download a provenance graph generated by NetKarma from the Portal.  The downloaded graph is an XML file based on the Open Provenance Model (OPM) standard for provenance.  For very large provenance graphs, the NetKarma plug-in can be used to visualize and explore large provenance graphs using the desktop version of Cytoscape (the web version of cytoscape is used in the Portal).  In this section participants downloaded provenance graphs for experiments we had run on both NS2 and ORBIT and loaded into the portal using the corresponding NetKarma adaptors.   The provenance graphs for these experiments differ from the XSP experiment in that whereas the adaptor for the XSP experiment uses the manifest to incorporate the topology of the experiment into the provenance graph, the focus of the NS2 and ORBIT adaptors is on capturing the success of each packet transferred.  This focus on the packet level results in large provenance graphs, but as participants were able to experience by loading the graphs for both experiments into the copy of Cytoscape included in the tutorial VM, they could quickly see the performance of NS2 and ORBIT experiments as to packets successfully transferred or dropped by using visualization capabilities included in the NetKarma plug-in.

    27 During the Demo session at GEC14 we also presented a live demo that followed up on our tutorial to show the latest version of the NetKarma portal and the visualization of an ORBIT experiment using the latest version of the NetKarma visualization plug-in for Cytoscape.

     32Following up on our proposed changes to the MDOD at GEC13 and subsequent discussions, we presented an XML schema of our proposed MDOD that was shared with the Measurement & Instrumentation group to stimulate discussion and we presented a poster at the GEC14 Demo session along with the schema and an example based on the XSP experiment used in the tutorial.  The schema is discussed further in the sectin below on work performed this quarter.  At GEC14, we also participated in the follow-on discussion Wednesday afternoon regarding next steps for the MDOD which was hosted by Harry Mussman and Jeanne Ohren of BBN.  The proposed MDOD schema, supporting schemas, and the example based on the XSP experiment are included below in the documents section.
