We are currently putting quite a lot of documents into our TWiki, and several of these documents contain the sort of information that will go out of date after a while, for example instructions on using a tool, which may become invalid when a new version of the tool is released. I am wondering how we can keep track of such perishable pages.

I guess an obvious approach would be to add Metadata to the page to hold an expiry date for the page. Once that date is reached some predefined action would occur - maybe the person who last edited that page is sent mail asking them to review the document, update/delete it if necessary, and reset the expiry date to an appropriate further future date. Is there anything already along these lines that someone has worked on?

Not exactly what you want, but I created a Tmp web for temporary stuff (polls, setting up meetings, working drafts), where topics are removed after N days if untouched.

Actually the script cleans both the Tmp (with N=100) and Trash (with N=10) webs. I attach it: daily_cleanup

Thanks for that. BTW it looks like there is a buglet in there - the variable $days is never used and the 100 is hardcoded. So I think it needs a s/100/$days/g.

I have used the ActionTrackerPlugin to good effect for this sort of stuff. I just put the action inside an HTML comment and it works.

John, sorry for being dense. But could you expand on your suggestion of relying on the ActionTrackerPlugin for this capability?
