How the states are applied in different processes
State | Sending of Maintainer Email | Display of Green Leaf | Allowed State Data Grid (overridden by curation) |
|---|---|---|---|
Up to date | Leaf displayed | Can be complete | |
Due | Leaf not displayed | Can’t be complete | |
Overdue | Leaf not displayed | Can’t be complete | |
Long overdue | Not used | ||
Delinquent | Leaf not displayed | Can’t be complete | |
Special Case For Never/Live/Ad Hoc | Leaf not displayed | Can be complete (can be curated out if too old) | |
The logic behind the handling of Never/Live/As Needed is detailed in this ticket, but here is the important part:
treat “never” as always fresh (datasets that are too old to be relevant should be curated out anyway)
treat “ad hoc/as needed” as always fresh (datasets that are too old to be relevant should be curated out anyway)
treat “live” as always fresh
