name-suggestion-index ("NSI")
Canonical features for OpenStreetMap, collected manually and via the NSI Collector planet scan.
What is it?
The goal of this project is to maintain a canonical list of commonly used features for suggesting consistent spelling and tagging in OpenStreetMap.

How it's used
When mappers create features in OpenStreetMap, they are not always consistent about how they
name and tag things. For example, we may prefer McDonald's
tagged as amenity=fast_food
but we see many examples of other spellings (Mc Donald's
, McDonalds
, McDonald’s
) and
taggings (amenity=restaurant
).
Building a canonical feature index allows two very useful things:
- We can suggest the most "correct" way to tag things as users create them while editing.
- We can scan the OSM data for "incorrect" features and produce lists for review and cleanup.

The name-suggestion-index is in use in iD when adding a new item
Currently used in:
- Rapid
- iD (see above)
- Vespucci
- JOSM presets available
- Osmose
- osmfeatures
- Go Map!!
- StreetComplete
- Every Door
- All The Places
