| taginfo: check_date:poi:* |
The check_date:poi=* keys are used on ways, typically a street segment, to document when all adjacent objects of a specific type were last surveyed for being mapped in completion.
This tag does not indicate that all details of the POIs are correctly mapped or up to date. It only indicates that each POI of this type that existed at the time of the survey is present on the map. Whether individual details of a POI are still up-to-date should be recorded separately on the POI itself, using tags on the corresponding node or area.
If a segment of way does not contain a certain POI, but surrounding area do, consider adding a check_date:poi=* to confirm, you validated the absence of a particular POI by survey at this date.
The syntax is:
check_date:poi:<key>:<value>=YYYY-MM-DD
Where <key>=<value> is the tag of the adjacent object type that was checked. The date should be specified using the 
ISO 8601 format YYYY-MM-DD.
Examples
A residential street surveyed for all adjacent trees on 17 February 2026:
highway=residential[...]check_date:poi:natural:tree=2026-02-17
A residential street surveyed for all adjacent fire hydrants, and all are mapped, on 6 December 2025:
highway=residential[...]check_date:poi:emergency:fire_hydrant=2025-12-06
Negative Example
A residential street surveyed for all adjacent street cabinets on 18 January 2026, and none were found, and none are present on the map:
highway=residential[...]check_date:poi:man_made:street_cabinet=2026-01-18
