place=* together with addr:country

[DenisCarriere]

Mixing addr:* tags with place=* is not a valid combination set of tags, instead use is_in:country, is_in:country_code tags.

I'm currently trying to fix OSM inconsistencies.

I see you've been adding is_in:country & is_in:country_code, which is great!

However, this is information is duplicated from the addr:country tags, also many of the Russian places had those tags added in 2009 to 2012.

These are warning message in JOSM which usually confuses a new OSM editor thinking there's an error.

Since there's a LOT of places (over 20K) in Russia alone that have these addr:country tags, I'd like your feedback before I do anything.

Reply from Miroff:

Back in 2011 we had massive discussion on addressing scheme in Russian OSM community. At that time I made some experiments with addressing, and it looks like those tags are result of this experiments.

After a while Russian community committed de-facto addressing scheme described here (in Russian): https://wiki.openstreetmap.org/wiki/RU:Addresses We consider OSM as a spatial database. That means we use positional relations instead of direct tagging. E.g. location of a city within a country should be finding by presence of city point within country polygon. As far as I know, most software utilizes this scheme either directly or during preprocessing of the data.

As for addr:country and addr:region tags on place=* nodes, back in 2012 it was a common template we used. Mixing addr:* and place=* wasn't deprecated at that time.

I believe, those tags may be removed safely, but of course I cannot guarantee nobody uses it.
