This is a Q I think I already know the answer for, but I'll try it anyway: is there a way to set Harvester to re-harvest/refresh selected archives on schedule? Looking at the documentation it appears that you can only re-harvest manually via the admin interface, or via the command line. I had a quick search on this forum for "harvesting" and there was a thread on "automated harvesting" (http://pkp.sfu.ca/support/forum/viewtopic.php?f=4&t=1624&p=5016
) but it wasn't relevant to the Q as far as I could see.
I strongly suspect that the answer is to set up a cron job to run the command on a daily/weekly/whatever basis, which if
your sysadmin allows users to run cron jobs is simple enough. The problem arises when this is barred to ordinary users, as is the case at my university, or when Harvester is hosted on a Windoze box, as is the case with a test installation I've got going.
