[OSM-talk] Representing places with no housenumber

[Edoardo Yossef Marascalchi]

in Israel a boulding on a corner between 2 streets have 2 addreses, one for
each street (or even 3 or more...).
the local authority register the building just on one of the possible
addresses for tax purposes but all of them are valid and usable.
the more, each if them have a distinct 7digit zip code

in italy, in some cities, each shop facing the street have a distinct house
number from the building main entrace (i.e. building is 17 shops are 17/a
17/b.. and a shop spanning more windows could have more than one of them)

in venice house numbers are unrelated to the street name but to the
neghboorhood (sestriere).

in some mountain community, detached houses (maso) sometimes didn't have a
house number nor a street name and are referred just by the family name

so, the address uniqueness is just a state of mind but we (all of us, i'm
not a royal) need to find a way to represent them in a database, something
very little flexible.

stop arguing about uniqueness and start offering solutions.
even it there will be duplicate addresses worls won't collapse.

An example from Germany:

https://www.izb.fraunhofer.de/de/impressum.html

The whole campus just fills up the complete street. Hence, the street
alone makes it already unique. I can confirm from having worked there
that it has indeed no housenumber.

Best regards,
Roland
