  If you have a highway=cycleway railway=abandoned, what does the start_date

  *start of rail operations?

 IMHO the last one:
 *opening of the cycleway

According to the wiki (1) start_date is the date the construction of
feature finished (could related to end_date).
Here there is 2 features, but only one active.
start_date should be related to cycle_way

a railway:start_date could tell the railway construction... perhaps.

[Tagging] Locating the voting page for a tag

2011-03-13 Thread Paul Norman
While looking into some issues around a bad import, I ran across
http://wiki.openstreetmap.org/wiki/OpenSeaMap/Lights_Data_Model but was
unable to find a page with voting or discussion. Although the tag voting
process has many flaws, this doesn't say it was added because it is what was
commonly used. Does anyone know where the voting page is? I've gone and
fixed some of the flaws. For example, the page was implying that something
is render a certain way, but was really just making rendering suggestions.

There is the project openseamap.org who are (I guess) using the
rendering they describe on their page in the wiki. I suggest you
contact them if you want to make changes to their userspace in the
wiki.

Paul,

You must have missed these words at the top of the wiki page:

These definitions relate to node tags in the OSM database which will 
render on the OpenSeaMap charts


i.e. The renderings defined are not those of the OpenStreetMap renderer, 
but OpenSeaMap's own renderer.


That is also why you have found no tagging discussions, since these tag 
definitions are not intended for the Street Map.


I have reverted the page.

Regards,
Malcolm Herring

2011-03-13 Thread Paul Norman
People are adding these tags to OSM, presumably based on the wiki page.
They're on the osm.org wiki, how do they not apply to the osm database?

Also, I'm not sure what you mean by the OpenStreetMap renderer. There are
dozens of renderers that work from OpenStreetMap data, of which OpenSeaMap
is one of them, along with MapQuest Open, osm.org mapnik, osmarender, etc.

Paul,

They do apply to the osm database (These definitions relate to node
tags in the OSM database).

 Also, I'm not sure what you mean by the OpenStreetMap renderer. There are

Some people refer to the mapnik layer at osm.org as The OpenStreetMap
renderer. We can try to treat all renderers equally, but inevitably
the one on the front page will get most of the attention.

But Malcolm is merely saying that general purpose renderers (like
MapQuest Open, osm.org mapnik, osmarender, etc) are not expected to
implement the rules on the wiki page.

 is one of them, along with MapQuest Open, osm.org mapnik, osmarender, etc.

Not every tag has to be voted on.  Some wiki pages exist to document
tagging schemes that are already in use,

 I’ve gone and fixed some of the flaws. For example, the page was
 implying that something is render a certain way, but was really just
 making rendering suggestions.

In OSM, there are many many renderers.  As others have pointed out,
OpenSeaMap renders using different styles to mapnik, osmarender, cycle
map, etc.  Please dont 'fix' pages just because your choice of renderer
doesnt support some feature.

If you really want to correct the situation, work the other way and make
your choice of render follow the rules that 'something is rendered a
certain way'.

If shop=florist doesnt render in renderer A but it does in renderer B,
that doesnt mean that you should rewrite the wiki page to say that
shop=florist is really only a rendering suggestion, but you could for
example re-write it to show what renderers DO support the tagging
combination.  In this particular case, the relevant line is at the top
of the wiki page, telling you what renderers support the tags.

David
