Address overlay: Don't allow to add addresses to buildings in Italy

[Mannivu]

Not really a bug, but I've found that with the "Addresses" layer enabled users can add addresses (addr:street and addr:housenumber) on buildings in Italy. This is a wrong method of mapping, since in Italy addresses are not linked to the building, but to the entrance of a property. For this same reason, the quest asking the address of a building has been disabled long ago on StreetComplete (#714). However, with the new layer users can add the address on building.

The quest is disabled

No asking on the building

Selecting the building, I can add the address

Correct, this is the overlay. It does not ask the user to add housenumbers anywhere, it just enables him to add them, either on buildings or on nodes. The same as any other editor.
Whether the user wants to follow community consensus or not is up to him, like with any other editor.

This is incompatible with the base assumption from the README:

It can be used without any OpenStreetMap-specific knowledge.

The app is aimed at users who do not know anything about OSM tagging schemes but still want to contribute to OpenStreetMap.

which determines UX design, quest eligibility, SC's self-advertising, community advertising and word of mouth.

Use cases:

• Tourist mapper prefers SC to stay safe from shooting himself in the foot.
• Local community or mapper chooses SC to lure clueless victims into OSM.
  • Is your official position that a mapathon aimed at newbies should always begin as Do not click on buildings in the addresses overlay, yea we know, but it's wrong.
• Local mapper who learns tagging by using SC: if SC allows it, then it must be allowed, no?

Actually what could be done relatively easily would be to make buildings whose center point is in Italy not clickable if they do not have an address set on the building outline already. (after all, if the data is already present, it should be possible to update it)

This would only be okay if it is not accepted practice anywhere in Italy to map addresses on building outlines. Do you have documentation (wiki link) and data (e.g. overpass or sophox query that shows that only an insignificant number of buildings have addresses tagged)?

First of all, I thank you for taking this proposal into consideration.

We have that guideline on OSM Wiki https://wiki.openstreetmap.org/wiki/IT:Addresses#Come_inserire_gli_indirizzi_2 (see the bold sentence starting with NON.

What about making a building unclickable if the country is in AddHousenumber's enabledInCountries, which lists the countries with the community discussions / rationales (see here)?

This is the easiest option, no-maintainance, future-proof (if the list changes) and will save you a ticket for each bypassed local community guideline. Do I open a separate ticket (or 7 tickets if you prefer) for the other countries?

No, because these were disabled for various different reasons that do not conflict with adding housenumbers to buildings. E.g. in France it has been disabled because in some places it is considered okay to add housenumbers in the Italian fashion (at entrance gate to property).

What is still required here would be a link to data that shows that what is written in that wiki article is actually followed.

Hum, no. Adding housenumber in the italian fashion is the best practice and what wants the french community. But it's ok to add housenumber on buildings. Not good, but ok. So I do think that, for France too it should be impossible to add housenumber to building with the address overlay.

[westnordost]

best practice ≠ not allowed

Also, please note the last sentence of my last post.

Actually this is not followed in Italy quite often, e.g. https://www.openstreetmap.org/way/348322410.

Address on that way was created back in 2015., and if I understand it correctly the decision about address mapping was not reached until 2018., so unless they had fully completed some massive bot (or organized edits) campaign, it is likely that there will still be pre-2018 leftovers... (but note that I haven't done any serious research into the subject)
