That number was mostly driven by 1) the notion that trying to
reduce false alarms is good 2) an assumption that if you notice a
problem, the metadata source can fix quickly after being notified
(less than a day). If either of those isn't true, then maybe > 24
hours does make sense. <br>

<div>Take the InCommon metadata, for example. I know it has a
valid period of 2 weeks, and I know that just about every
business day that metadata changes, and should be (if I have
recommended refresh settings) therefore refreshed about once a
business day. So if see that the validUntil of my copy is less
than a week, then something is going wrong. it doesn't take
getting to within 24 hours or less of it expiring to know I have
a problem and things aren't working as I'd expect.<br>

Sure. If you want that much notice, then you can set to 7 days or
whatever. But there could be legitimate reasons why the "expected"
update schedule changes for some period of time (i.e. no updates to
publish), and then corrects itself well within days of expiration.
You would get a false alarm in that case with a lengthy threshold.
If you're ok with that, then that's fine.<br>
<br>
As I said somewhere in this thread, it really comes down to how
paranoid you want to be. More paranoid = greater chance of false
alarm. And if you have a 7 day threshold and the warning fires, you
have to decide whether you go and pester the metadata source
immediately, or wait a few days to see if it resolves on its own.<br>
