The tag addr:place has been used to locate one element inside another
addressed element. See this example for shops within a Tesco Extra store
This usage is useful but probably a little difficult to consume,
particularly as there seem to be rather more usages of addr:place as a
synonym of addr:city.
The idea is that one looks for the thing named in addr:place within the
immediate locality (I presume this should be mapped as an area and the node
or way with the addr:place tag should sit within that area). Examples of
usage include: post offices in shops, shops in hypermarkets, hospitals,
restaurants & bars in hotels, some retail & business parks where the
address is solely for the area not the street, possibly shopping centres
etc.), university campus buildings, etc. This overpass query shows how this
has been used in the Nottingham area: http://overpass-turbo.eu/s/5CO,
largely by Will. The benefit of using a tag like addr:place is that address
information does not get duplicated confusingly (e.g., on a bar, 2
restaurants and a hairdresser all inside a hotel).
There are at least 2 post offices in other shops in Nottingham which I
mapped. at Wilkinson
now Wilko !) in Bulwell I never checked inside the store so rather lazily I
just tacked on the amenity tag; at The Co-operative
supermarket (need to check how this is branded these days too) I did survey
inside and added the post office & associated post box reasonably
accurately. The distinct disadvantage of putting the shop and amenity tags
on the same node is that only one gets rendered. (Incidentally, this
applies to many smaller sub postoffices, they are actually located within a
convenience store or similar, but we rarely try and separate the locations)
