Would be nice if the event builder .ini objects were stored in the same DB as the reader .ini objects. A reader .ini object would then link an event builder .ini file that should be used for that data by writing the name of the .ini doc to the run['trigger']['mode'] field. The same will hopefully be done for the data processor.
Right now reader .ini files are in online.run_modes. Trigger ones could go in online.trigger_modes or something like that.
Just a wishlist thing for unification of these parts, so no hurry on this.
