Re: [Tagging] Power poles tower : power vs man_made

2013-08-17 Thread Janko Mihelić
I agree with the reasoning behind man_made=pole, but the semantic
infrastructure behind osm is not yet strong enough. I think a second layer
should be there, a semantic model which says what certain key-values
actually mean, and which could be easily changed. The renderers could then
be bound to that model, not the rugged key-values.

this would allow for a whole new interpretation of the term map roulette ;-)

I totally agree with Janko.

A meta-tagging model will allow more agility when tag a replaced or
deprecated.

Boundaries describe an area but you are right that they are not really
boundaries, especially if the border lines are not clearly defined

 The problem is, that multipolygon don't work in 2 cases:
 - The areas touch each other.
 - The areas are multipolygons. A multipolygon as a member in a other
 multipolygon is not allowed.
 
 Either we allowed this, or we need any relation which collect these
 things...

You can always split the ways and use the parts tagged with outer/inner

 (What the renderer do, is not primary. If we find a good tagging, the
 renderer should follow the tagging, not backwards.)

Forget the renderer but think about all software. It is probably easier
to use an established system with one more subtag than clone the system
and use a new type and at least admin_centre would be useful.

I'm under the impression this discussion is leading to ever more complicated
ideas, due to the problem that the features we want to name on the map
are not really clearly defined areas.

Maybe we should try a completely different approach. We could draw
a way along the approximate center line of the feature and tag it
with name=*, topo_feature=mountain_range|ridge|valley|...
A renderer that wants to display the name should draw it along that
way with the length of the way giving a hint about the size of the
feature.

+1

 a way along the approximate center line of the feature

or we could simply admit that OSM project is currently unable to map
such big features with fuzzy borders...

+1, a way is surely not a good representation.

 If ever there was a good use for ;, this is it:
 
 reuse:goods= books; household_items; clothes; shoes; pet supplies; pet
 food; unrestricted;

I do not agree. Under this scheme it is not possible to say that only a
certain kind of good is accepted but not others.

I do not see how one could know wheather the list is complete.

Let’s take “reuse:goods=books” for example. It could mean that only
books are accepted, nothing else. But it also could mean that books are
accepted and other goods as well (which aren’t just mentioned here
because the list is incomplete for some reason).

And what’s that “unrestricted” in your example, by the way?
“unrestricted” is not a good. I don’t know what it means but it looks
like it belongs to another tag instead.
