Unify apartment (아파트) tagging

단순히 아파트 동호수를 101, 102, 103 등으로만 표시 하는 것은 문제가 있다고 본다. 검색창에 101만 처도 해외의 우편 번호가 먼저 나온다. 실생활에서 A아파트 102동이라고 하지 숫자로 부르지는 않는다. 검색엔진을 고려해서 숫자만 붙이지 말고 101동, 102동, 103동, 201동처럼 동을 붙여서 적어야 찾기 편해진다. 네이버 지도나 카카오맵에서도 그렇게 표기하지만 동을 꼭 붙인다.

Can be translated by :

I think there is a problem in simply displaying the number of apartment buildings as 101, 102, 103, etc. Overseas postal codes appear first in the search bar even for 101 million places. In real life, it is called A Apartment 102, not a number. Considering the search engine, do not attach only numbers, but write dongs like 101-dong, 102-dong, 103-dong, and 201-dong to make it easier to find them. It is marked as such on Naver Maps and Kakao Maps, but the dong is always attached.

2 points were raised by @depth221 :

1. In most cases, "name=101" or "name=101동" are used in terms of the 'name' of apartment buildings. According to the wiki, if there are multiple sections of a single building, or if there are multiple buildings within a single complex, you can tag each area/building with an addr:unit tag [1]. On the other hand, the addr:flats tag is used to indicate multiple household numbers (e.g., addr:flats=21-40)[2]. In fact, the apartment dong/ho is closer to a part of the address system than the name, so why don't you use the addr: series tag to indicate it?

2. Although there is no "동" on the wall of the apartment, the official name is "101동", so I think addr:unit=101동 would be better than addr:unit=101. In addition, the addr:unit tag can be used not only for dong, but also for the building's area name (section A, section B, etc.).

My comments were :

1. I like the idea of using addr:unit. Maybe we can keep name=101, but use addr:unit in top of it

   • But we might want to put the whole complex name under name instead (like : name:ko=자양현대홈타운7차아파트)

2. For using 동 or not, we can have the idea of using addr:unit:ko tag key. While I don't see any localization used in this tag (like in the "name" tag for instance ), I think that can make sense to have addr:unit=101 and addr:unit:ko=101동

   • At the end of the day, when writing an address, we don't necessarily put the 동 in English, and using both tags can reflect that.

Also, wanted to link here the wiki we need to update once a decision has been taken :

한국에서 name 태그에 한국어를 넣듯이, addr:unit=101동으로 하고 addr:unit:en=101 혹은 addr:unit:en=101dong으로 하는 게 어떨까요?
사실 다른 국가도 자국 주소 체계를 기준으로 주소 태그를 지정하고, 타국의 주소 체계는 그다지 고려하지 않으니까요.

As a name tag in Korea contains a Korean name, so how about tagging like addr:unit=101동, and addr:unit:en=101 or addr:unit:en=101dong?
In fact, other countries also tag their addresses based on their own address system, and they don't really consider other countries' address systems.

Very good point, let's do this.

Here is my suggestion then according to our discussion :

It's made using Excalidraw will put the source file in the repo if you want to complete it.
Few comments then :

• I took the liberty of pushing addr:flats to a node to show the entrance door
  • Not sure if we should use this tag and / or addr:door at the same time
• The dead-end street to be go in front of the building is highway=service, but what about the street connecting all apartments?
  • I believe this is a question for another thread, let's focus on buildings / area here if that's ok
• Now I found that name and addr:unit are quite redundant, I don't think it's an issue (more tags is always better), but maybe we can improve this
