[OSM-talk] Good practices violated?

[Jakub]

I do not want to sound too radical, but it is quite astonishing, how 
*Good practices <http://wiki.openstreetmap.org/wiki/Good_practice> can 
sometime radically differ from apparently widely accepted and even 
promoted usage.* Let me point out an example of what I mean, but I 
beleive that the problem is much wider than this particular case:

*Countries on nodes vs areas vs relations*

On one hand there is a:

  * widely used practice to map country *both as node and relation*
    (and sometimes area)
  * suggestion that the place=country should be placed on node see
    Place <http://wiki.openstreetmap.org/wiki/Place>
  * suggestion that Key:place
    <http://wiki.openstreetmap.org/wiki/Key:place> should be used on
    node or area (relation not mentioned)
  * suggestion to

and on the other hand there is a:

  * PrincipleDon't map for the renderer
    <http://wiki.openstreetmap.org/wiki/Tagging_for_the_renderer>-
    which is clearly violated by tagging node as a country, because
    country is not a node and in fact this node is only ment for
    renderer (supported by giving this node a label role in country
    relation)
  * Principle One feature, one OSM element
    <http://wiki.openstreetmap.org/wiki/One_feature,_one_OSM_element>
    - which is clearly violated by fact that the tags are repeated
    both on node and realtion (or area). This practice is not only
    used it is also encouraged by wiki pages.

Now, please do not get me wrong, I might be wrong and there might be 
some reason for that. If there is one, I would like to correct the 
documentation and rewrite Good practices (or list exceptions to them). 
If there is no reason I would like to clan up the data, but surely 
there should be some consensus on that and the consensus should be 
very well documented so there is not confusion in the future.

Thanks for help

Jakub

PS: I beleive that this problem is much more general, it is also true 
with all sorts of regions, cities and villages. Names are rendered two 
or three times and is not good at all.
