    4646Two of the goals of NetKarma are to: (1) provide experimenters with the provenance of their experiment based on the events that occurred in their experiment, and (2) to capture provenance while minimizing the additional instrumentation needed in an experiment to capture provenance; ideally with no additional instrumentation.  For ORBIT experiments run using the ORBIT traffic generator (OTG), the NetKarma adaptor can capture provenance wiht no additional instrumentation as illustrated in the following diagram.

    4949As seen in this diagram, the provenance of an experiment run on ORBIT can be captured in NetKarma using the ORBIT NetKarma adaptor that ingests data that is already generated as part of the experiment.  This includes: (1) the script for the ORBIT experiment, (2) data retrieved using the OMF interface's "info" and "list clients" methods, and (3) data retrieved from the OML database.  The adaptor combines these data sources to generate event notification messages that are sent to the NetKarma server, where they are combined to create the annotated OPM graph for the experiment.
