Expiration date

Hi,

Thanks for adding your feature request here.

In my case, i need to add an "expiration date" in file information.

It will be useful to add this parameter to "unpublish" files (job deadline for example).

This is the first time I hear about this idea. We need to study more about how popular it is to add our planning.
Anyway, we noted that for a future release!

Cheers,
