Hi,
I think a valid_from and valid_to-field would be a great idea. Especially for queries on
the db.
But I think it is a fundamental design decision and I'm not sure if it's possible
to integrate now...

Seconded.
This would, for example, allow next year's train timetables to be loaded
into the database prior to their period of validity, and for the cutover
between last year's and this year's timetables to then happen
automatically at the appointed date.
