OpenStreetMap
landuse=residential classifications: There are several different that could fall under this... single-family, townhomes, apartments, high-rise apts/condos, mobile homes, etc.
A clearer definition of the difference between landuse=commercial, =retail and =industrial. Lots of offices are considered in zoning as 'light industrial' and called 'industrial parks', as opposed to 'heavy industrial', traditional industry with smokestacks and factories.
Fraternal lodges/meeting halls: Still lots of these around, though many of them are quite old, not just the buildings, but the average age of the members.

We have residential=*, for example, in Russia we use residential=rural and residential=urban. The same can be made up for other landuses. There is no 'official' in OSM, only what you create.

I’ve been tagging fraternal lodges with amenity=social_club. There’s also amenity=public_hall, amenity=social_centre, and building=hall for similar facilities.
