Errata: StreetComplete is using check_date, not survey:date

[matkoniecz]

survey:date (used by StreetComplete for instance to mark when a real-world object was last checked)

As far as I know StreetComplete is using check_date, not survey:date (data stored in survey:date is parsed, but StreetComplete will not add this tag)

See https://github.com/streetcomplete/StreetComplete/search?q=check_date https://github.com/streetcomplete/StreetComplete/search?q=survey%3Adate https://taginfo.openstreetmap.org/keys/survey%3Adate#projects https://taginfo.openstreetmap.org/keys/check_date#projects (though StreetComplete taginfo was sadly published after this part of report was written...)
