Added the most relevant Features of SAREF4CITY: Facility, AdministrativeArea and CityObject (which is a s4wear:PhysicalObject).

s4city:Facility replaces s4wear:Area.

Living organism and Physical object are geosp:Features; i.e., their spatial extent can be described. A Device is a physical object.

The terms Location, hasLocation, latitude and longitude are not needed anymore.

A wearer is a living organism, and we have a class in the ontology for that. So we can be more specific.

Updated the ontology and created the first example.
