Workflow¶
The reminder is controlled by two variables:
Time from which records are obsolete
Period after which users should be reminded again
Example:
obsolete if older than 6 months
users remind after 2 weeks
The timestamp of the records that are deprecated will be changed to:
-6 months +2 weeks
Find deprecated records¶

Illustration 1: Three records are out of date (left of the point -6 months)¶
Illustration above should be clear.
Update deprecated records¶

Illustration 2: The three deprecated records are moved to -6 months +2 weeks¶
The deprecated records of the illutsration 1 are moved to the point -6 months +2 weeks in the illustration 2.
The timestamp of these records is set to now -6 months +2 weeks.
Now the three records will be deprecated in 2 weeks. If the frontend user won't update these records, he will get a reminder in 2 weeks again.
