 Would it be better to have something other than yes to mean legally 
 enshrined access permission to protect against people tagging stuff as 

 yes without fully understanding what it means (i.e. people not 
reading 
 the wiki)?

I think it would.  I suggest access=highway

It would have to be contained within the foot, horse, bicycle, and 
motorcar tags though, so that the official rights of *each* mode of 
transport can be described.

A path with horse,foot,cycle=yes still isn't a bridleway though (e.g.
on a bridleway, cycles are permitted but the surface doesn't have to
be suitable for cycling - a situation more complex than just
cycle=yes).  The legal bridleway has more attributes than just who is
allowed to travel along it (e.g. races can't be held on bridleways)

It also can't be easily updated if the laws change - bikes weren't
always allowed on bridleways, and hasn't the list of vehicles allowed
on byways changed recently?

The issue isn't so much discussion of loads of new tags, but the
potential loss of existing data if people start using
highway=bridleway for something which isn't one (or use horse=yes
instead of a bridleway tag, which has pretty much the same effect)

It depends what's meant by yes - does it mean official, legal rights? On 
reflection maybe designated is better than yes.

(e.g.
on a bridleway, cycles are permitted but the surface doesn't have to
be suitable for cycling - a situation more complex than just
cycle=yes).  The legal bridleway has more attributes than just who is
allowed to travel along it (e.g. races can't be held on bridleways)

One could sort this out though by means of the surface tag, and indeed 
any other tags that might be relevant.

But what is a bridleway?

From your talk it seems like the tag can only be used for something that is a 
bridleway in the eyes of the British (or possibly local) law. Except nowhere 
on the wiki can I find anything that says that. Both Map Features and the 
Tag:highway=bridleway read:
For horses, (in the UK, generally footpaths on which horses are also 
permitted)

If in the Netherlands we would limit the tagging of bridleways (dutch: 
ruiterpaden) to what is one legally, then we wouldn't have many, as I don't 
remember ever having seen the official sign for it. (A round blue sign with a 
white horse and rider) However I have seen plenty of paths which are signed 
with a rectangular sign with the word ruiterpad and/or are physically only 
suitable for horse riders. (too narrow for vehicles and with deep loose sand; 
think dry part of a sandy beach)

So to sum it up: Do the ways currently tagged with bridleway conform to your 
narrow definition or is there already no data to loose, because it is already 
use for ways which are physically, but not legally paths for horses.

I would consider all the existing tagging as of suspect
interpretation. For example, foot=yes is almost entirely meaningless
as right of pedestrian access enshrined in law since it's been added
by default to every highway=footway in potlatch for some time.

But then again, it's a wiki, so all the data will always be of
suspect interpretation to a greater or lesser extent :-)

Cheers,

I think it's been implied for a long time that all the values for the 
access key apply to all of the mode-of-transport keys as well. 
Certainly http://wiki.openstreetmap.org/index.php/Key:access seems to 
suggest that it does.

Agreed.  I would expect that all the access tags have that problem, not 
just foot.  I don't think the yes value has ever been defined in that 
manner, so I'm certain it's been applied to routes which are not 
rights-of-way.

I know I've always understood yes to mean that [vehicle type]s are 
capable of traversing this route, and are not forbidden to use it. 
Certainly nothing currently in the wiki appears to contradict that.

I'm also quite certain that footway/cycleway/bridleway have been applied 
to routes which do not follow the UK definition.  (In other words, there 
is already no right-of-way data to lose).

Yes, but lots have been tagged not based on legal status, and we don't
want to misrepresent those. It's better to have no data than wrong data
on a way.

2008-05-17 Thread Nick Whitelegg
Are there any use-cases for keeping the legal designations of
rights-of-way (aware that this is very UK-specific..)

Since permissive tracks are not legal rights of way, and permission can be 
withdrawn at any time, I think we should distinguish between them.


e.g. perhaps someone wants to use our maps to check that all the
rights of way in their area are properly accessible.  Or someone using
an OSM map is challenged by a landowner and 'the map says I'm
permitted to herd sheep along this path'

we seem to have lost 'public footpath' information already by using
the same 'footway' tag for anywhere that you appear to be able to walk
nevermind if there's a footpath sign at the end.  proposals like this
might make 'real bridleways' disappear too, into a mix of places that
at first glance seem passable by horse-riders

But that's what foot and horse are for.
highway=path could easily be used to distinguish public and permissive 
footpaths and bridleways.

e.g.

highway=path, foot=yes - public footpath
highway=path, foot=permissive - permissive footpath
highway=path, foot=yes, horse=yes - public bridleway
highway=path, foot=yes, horse=permissive - public footpath with permissive 
horse rights
highway=path, foot=permissive, horse=permissive - permissive bridleway
highway=path, foot=no, horse=permissive - horse only path (such things 
exist)

then if highway=path is replaced by highway=track in all the above cases, 
we can also distinguish physical surface. I think 
highway=path|track|service, surface=[whatever], and 
foot|horse|bicycle|motorcar = yes|no|permissive|private cover all cases I 
can think of.

Yes, that's why I started to add certain road signs in my area to our
database, especially those denoting foot and cycleways.  Thus far I
used traffic_sign=z240 etc. where z240 means the reference number
assign to it in the StVO (legal text about road transport):
http://bundesrecht.juris.de/stvo/index.html and
http://bundesrecht.juris.de/stvo/__41.html (interesting road signs).
