Demo story line for provenance collection:
. purpose: to show how provenance is collected and used
. there are two groups of web services
. 1st: the JPL services
. 2nd: the CMU provenance service
. the 1st group is the “server” for our external users
. at the same time, the 1st group is the “client” of the 2nd group
. therefore, a JPL service will, after obtaining the results, call
the CMU provenance service to submit the provenance data
. use this JPL service to demo:
http://cmda-test.jpl.nasa.gov:8080/assets/html/twoDimMap.html
. fill in the text box “Execution purpose:” with something like “demo 5/23
10:20AM”
. hit “Get Plot” to see a resulting plot
. go to the provenance server front page:
http://einstein.sv.cmu.edu:9033/
. log in as “[email protected]” using password “lei”
. select “Collaboration” -> “Service Execution Log”
. reload the page if already there
. find the log corresponding to the last run
. click “see details” to re-run the service
. before a re-run, right click the image and choose
“Open image in new tab" to make sure that
it resides on the provenance server. This demos
that the provenance data is indeed collected by the
provenance service.
