admin_centre should handle for multipolygons

[iav]

admin_centre should work for places multipolygons as for boundary as in card #6792.
role admin_centre should be point, optional and not more than one.
In case of name property is present for relation and point, it should be equal for relation and admin_centre point.

Can you attach a sample .osm file ? Thanks.

place multipolygon with admin_centre

I think admin_centre is not a offical role for multipolygons only for boundaries but I can not find a reason for it.

Right now I move all tags to the relation and use the node in the outline to keep the history but that is not the best solution.

At least for places objects - it helps to place a place name text to more suitable place on map

and mapnik renders the name twice ! (In my area often even more as the multipolygons contain several areas and there exists separate multipolygon relations for boundaries.)

Do not get me wrong. I am in favour of "admin_centre" but we need to make this official and have mapnik use it !

The part that JOSM can fulfil is to get rid of "Role admin_centre unknown - Role verification problem" – did you mean that?

Although Frederik introduced it, the type=multipolygon for boundaries is still somewhat broken. I'm not in favour of improving the support for this.

Mainly it would mean to define types base on relation type and additional key (in this case administrative), which is not supported yet.

The problem is, that type=multipolygon administrative=... is a boundary, but type=multipolygon no "administrative=..." is something else (an area on the earth). I don't like the idea of introducing data types of "this is an area except it is ...". As soon as somebody introduces something new, it will break all software.

All the other multipolygons are some way of land use, but boundaries are an additional layer overlaying the land uses.

I map on both sides of the Rhine. Once I changed some multipolygon to boundaries on the right hand side of the river and received a few days later a not very kindly email asking me to revert my changes and stick to local custom. Seems to me that the wall in many minds presists concerning (national) borders.
No border, no nation ...

Or setup a proposal and create 1000 relations to call it official.
While this would be in my favour I am not sure about it as the warning seems to be correct for now.

Ok, would you, please, to check a usage count of type=multipolygon place=*?
