In Brazil, admin_level=4 is state level, so it would be state_capital=yes. I've never really thought about it in depth because Brazil only has 2 administrative levels with a "capital" city and the country only has 1 capital. This is how it looks like in Brazil now: 1. Node tagged as place=city+sta

Please explain why admin_level on place nodes harms the database, or refrain from removing it. Thanks. I actually put it back in Berlin after I took a 2nd closer look at Germany. Which then actually revealed that all our state capitals are tagged with admin_level=6 when they should be 4 as far

I really don't think this is considered a standard tag by most people. In taginfo we can find keys like capital_city, capital_level, is_capital, state_capital, capital. As far as I saw, each key is concentrated on some parts of the globe. It certainly is not a "fact" that it is standard. I had cha

See also the use of the admin_centre in boundary relations. This allows a place to have a different role/importance for each admin area it is in. An interesting case is Amsterdam, which is the capital of NL but not the provincial capital of the province it is in (that's Haarlem). The tagging ref

Hello everyone, We're having a little discussion in the Brazilian community about whether the node tagged with place=* that represents a city should/shouldn't have an admin_level=* tag. The wiki states, since at most 2010 [1], that the admin_level tag should not be used on nodes. However, both Ber
