Looking at “staircase entrance” or “garage entrance”, or “shop entrance” these seems valid and comprehensive words, but my question for shop entrances would be: is it the kind of entrance (door, etc.) that defines it? If someone lived in a shop structure (not so rare in some places) which isn’t a shop but only an apartment (by use), and had a door to the street, would that be entrance=shop (because of entrance typology) or entrance=home (because it leads to a home)?</div><div><br></div><div>On a side note, those 8800 entrance=exit seem quite silly, they would probably better be tagged as exit=yes and entrance=no</div><div><a href="https://taginfo.openstreetmap.org/keys/exit">https://taginfo.openstreetmap.org/keys/exit</a></div><div><br></div><div>entrance=no can mean different things by the way, it can mean there is an entrance but it is not usable (e.g. emergency exit), but it can also mean there is no entrance and no opening (avoidance of doubt, e.g. a former entrance which was bricked or a potential entrance which isn’t used, in both cases it may have a housenumber e.g. in Italy)</div><div><br></div><div>Cheers Martin </div></body></html>
