[kepler-users] How to run kepler Command Line tool to generate provenance data

[Derik Barseghian]

Hi Madhavi,

I'm not aware of a way to have 1 kepler process launch and run 2 or more workflows in a row before quitting. You could simply run a series from command line like:
ant run-w...; ant run-w...; etc.
or write a script to loop through workflow files in a directory, and/or a cron job.

On a somewhat related note, Jing has added a scheduler module to kepler, which allows you to schedule a workflow to run periodically on a remote kepler server. Any resulting run-kars from these executions are written into a kepler repository (currently MetaCat). This module is not yet released, but will probably be available in the near future.
