Hi,<br>
<br>
I was wondering what's the correct use of the 'is_in'-tag in
Belgium (or Flanders in particular).<br>
When I search on openstreetmap.org for cities, I sometimes see the
detail it is in 'European Union'. <br>
<br>
For example, my own city Lier has following search result: "
<meta http-equiv="content-type" content="text/html;
charset=ISO-8859-1">
Stadsgrens <font color="#000000"><a moz-do-not-send="true"

Antwerpen, Vlaanderen, België, European Union"
data-prefix="Stadsgrens" data-type="relation">Lier, Mechelen,
Antwerpen, Vlaanderen, België, European Union"</a><br>
When I search for city Duffel:</font> "Stadsgrens <a
moz-do-not-send="true"

data-min-lon="4.46484470367432" data-name="Duffel, Mechelen,

data-type="relation">Duffel, Mechelen, Antwerpen, Vlaanderen,

<br>
As you can see, Lier is tagged correctly it is in the EU, Duffel
isn't. There are multiple other examples (Oostmalle, Zandhoven,
...)<br>
<br>
When I compare the tags:<br>

Actually, Lier is incorrect considering this relation:<br>

Lier is in Arrondissement Mechelen. You have to account for the
Administrative layers. Afaik, relations like this should replace
the is_in tag, I never really got that tag either.<br>
