[Talk-ee] Maa-amet Tase 6 (maaüksuse nimi) – addr:place või addr:housename?

[SviMik]

Hi all,

I have a tagging puzzle here. Maa-amet classifies address parts in the following way:

Tase 3 – asustusüksus ja linnaosa
Tase 4 – väikekoht
Tase 5 – liikluspind (tänav)
Tase 6 – maaüksuse nimi
Tase 7 – aadressi number

The problem is, that many buildings in Estonia do not have Tase 5 (street name), but instead have Tase 6 (lot name) and may or may not have Tase 7 (housenumber) at the same time.

According to OSM wiki, addr:place is "part of an address which refers to the name of some territorial zone".
Looks perfect so far, "the name of some territorial zone" is literally "maaüksuse nimi".
But...
1. addr:place requires place=* node or area to be mapped too, which is not really doable for every land lot.
2. I'm already using addr:place for Tase 4 (väikekoht, aiandusühistu, etc) which fits better for this role.

We could use addr:housename for this instead.
Indeed, Tase 6 is often used as a replacement for the street+number scheme, and in most cases is literally the property name.
But...
1. Sometimes Tase 6 comes with Tase 7 (housenumber). I'm not sure if addr:housename can be used together with addr:housenumber, the addr:housename sounds like it must be the final address part.

Examples with house number:

Harju maakond;Kuusalu vald;Leesi küla;Kasemäe;1
Harju maakond;Kuusalu vald;Leesi küla;Kasemäe;2
- here Kasemäe is tase6, not street (tase5), but it still uses house numbering. This example looks like addr:place.

Lääne-Viru maakond;Kadrina vald;Arbavere küla;Palkoja baas
Harju maakond;Kuusalu vald;Vihasoo küla;Pumbamaja
Harju maakond;Anija vald;Härmakosu küla;Härmakosu tehnopark
- here the last part is tase6 too. They don't have house numbers, and these examles do look like addr:housename.

So, the questions is: where exactly do I put the Maa-amet "Tase 6" address part in OSM tagging scheme?
And is it OK to use addr:housename together with addr:housenumber?
