Description

I came across some reverse geocoding results where Nominatim.php didn't return a 'locality'. In my opinion, this latlng query should have 'Purmerend' as its locality, as it's the municipal boundary:

https://nominatim.openstreetmap.org/ui/reverse.html?lat=52.50741&lon=4.93279&zoom=18
https://nominatim.openstreetmap.org/ui/details.html?osmtype=W&osmid=6593763&class=highway

Upon debugging, I noticed that inside jsonResultToLocation(), on line 209, 'municipality' was not considered a 'locality'.

$localityFields = ['city', 'town', 'village', 'hamlet'];

Is this a matter of definition?

Adding 'municipality' fixes my issue:

$localityFields = ['city', 'town', 'village', 'hamlet', 'municipality'];

Research direction

Start in Nominatim.php at jsonResultToLocation(), around line 209, and inspect how localityFields are used for the supplied reverse-geocoding result. Confirm that the municipality value from the Purmerend example is returned as locality, and verify the existing behavior remains correct for the other listed locality fields.
