Mark suspicious house numbers

[ltog]

Basically everything except numbers and letters in a house number is suspicious. Example:

http://tools.geofabrik.de/osmi/?view=addresses&lon=8.83320&lat=47.23168&zoom=18&overlays=buildings,buildings_with_addresses,postal_code,entrances_deprecated,entrances,no_addr_street,street_not_found,nodes_with_addresses_defined,nodes_with_addresses_interpolated,interpolation,interpolation_errors,connection_lines,nearest_points,nearest_roads,nearest_areas

(multiple housenumbers separated by comma)

[ltog]

Here's an example with a /: https://www.openstreetmap.org/way/232283028 Maybe we should add this character to the list of allowed ones?

Maybe there are "legal" housenumbers in other countries where we indeed have these special characters. Thus not so strict as in central europe ...

[ltog]

@stephan75 : Yeah, that might be. Do you have any references? If there is more specific data I might think about implementing regional rules.

[stephan75]

I only found some country specific hints about addresses in general at http://wiki.openstreetmap.org/wiki/Addresses ...without diving in that deeply.

We would need an own investigation about that via the popular OSM channels I fear.

Thank you for the new functions!

in Hungary the allowed characters can contains '/' and '-'
and sometimes spaces but this is very rare ..

example

60
60 62/B
60/62 
60/62/A 
60/62/B 
60/62A 
60/62B 
60-62 
60-62/A 
60-62/B 
60-62B

is it possible to add country specific validation rules ?

@ImreSamu : Thanks for the examples, that's very helpful. I will collect rules for different countries/regions at #93 . At the moment I don't know if and how osmi-addresses will support such regional rules. I will track progress under #92.

@stephan75 : Thanks for mentioning https://wiki.openstreetmap.org/wiki/Addresses , that's certainly a starting point. I'm hesitant to ask around for different rules as long as there is no support for #92, since I don't want to fuel unwarranted hopes.
