yes, I wouldn't use this tag if you are after tagging a generic
"architectural monument".

yes, might be exxagerated to add it to every interesting building, I know
from my own experience that not everybody is interested (or culturally
prepared) in seeing a lot of buildings.

yes, would NOT use this, as "architectural monument" is not a building
type.


My Idea is that you probably shouldn't tag something as "architectural
monument", as this is highly subjective and there is no absolute way of
telling something is a monument or not. Also this will vary according to
fashion. Adding attributes like the architect or the construction date will
already allow for basic filtering (getting maybe the more interesting
buildings), important buildings will also likely have an article in
wikipedia so adding this will also help identifying them. Every way of
tagging, which requires "voting" or "rating" of buildings in some way or
the other, is not suitable for OSM (is subjective, is an opinion and not a
fact).

I don't advocate it to be used exclusively, but it fits the current
definition (production and/or storage).

[Tagging] Metropolitan counties and other boundaries

2014-02-20 Thread Colin Smale
 

Hi, 

In the last couple of years I have put in a lot of hours maintaining the
UK's admin boundaries in OSM. Having started in Kent (home territory) I
have gradually been fanning out to cover more and more of the country.
Although there is a lot of consistency in the tagging, one thing I
noticed is that there are two schools of thought regarding Metropolitan
Districts. These are a subdivision of Metropolitan Counties, of which
there are six: Greater Manchester, Merseyside, South Yorkshire, Tyne and
Wear, West Midlands and West Yorkshire. 

The Metropolitan Counties still exist in law, and certain functions
(e.g. Fire&Rescue, public transport) are often governed at that level.
The Councils no longer exist as bodies however. The Metropolitan
Districts (which are styled as Boroughs or Cities) are therefore
effectively 99% the same as "unitary authorities". 

In the situation between 1974 and 1986 the tagging would be obvious:
both the County and the District would be boundary=administrative, with
admin_level=6 for the county and admin_level=8 for the districts. In
OSM, things have diverged a bit since then, and proper Unitary
Authorities are tagged as admin_level=6 putting them on the same level
as Non-Metropolitan Counties. 

The current situation in OSM is: 

 admin_level
County county tag county district
GM ceremonial n/a 8
Merseyside ceremonial n/a 8
S Yorks administrative 6 8
T&Wear ceremonial n/a 6
W Mids administrative 6 8
W Yorks ceremonial n/a 8 

I would like to normalise this tagging, and looking at the current usage
above and the wiki[1], propose that the Metropolitan Counties become
boundary=ceremonial, and the Metropolitan Districts become
boundary=administrative, admin_level=8. 

Are there any objections or other comments? If not I will make the
changes in a few days' time. 

By the way, I have been creating a wiki page to try to give an overview
of UK boundary tagging at [2]. Please look at it - any comments,
corrections, additions etc are most welcome, and if people feel it's
useful the content can be moved into a more "obvious" place in the wiki.


Thanks,
Colin
