[Talk-GB] railway:historic=rail

2013-05-13 Thread Richard Fairhurst
I've just been bitten by the minority, largely undocumented usage of 
railway:historic=rail on a bunch of dismantled/abandoned railways in 
Britain. Having exported some OSM data and done a few days' manual 
processing on it, I belatedly find that various lines are missing due to 
not taking account of this tag and I'm going to have to do a whole bunch 
more work. :(


Taginfo/Taginfo GB suggest that railway:historic=rail is not used much 
elsewhere in the world, and that railway=abandoned, =disused and 
=dismantled remain the popular choices. No client software appears to 
take any notice of railway:historic=rail.


Would there be any opposition to gradually reverting uses of this tag to 
railway=dismantled/abandoned, depending on what's on the ground?


The only documentation I could find (on a wiki discussion page, of all 
the obscure places): 
http://wiki.openstreetmap.org/wiki/Talk:Railways#railway:historic.3Dxxx_or_former:railway.3Dxxx_in_place_of_railway.3Dabandoned.2Fdismantled.3F

There is a special case, but I'm not sure that is what you are actually seeing. 
While the track bed may have been lifted, a number of 'historic' lines still 
have statutory orders in place designating them as 'protected'. For instance the 
line up from Broadway extending the GWR track from Toddington has to be treated 
as if it is active and the Broadway Bypass had to have a bridge built to allow 
for an electrified line to be run through. BR is unlikely ever to do that and 
the information is not visible on the ground, but it is available information.

I don't think Richard's original post was an invitation to discuss arcane
quirks of Britain's historical railway system.

I have raised the issue of wholesale tag changing several times recently,
and as this tagging is clearly not with the consensus of mappers either in
the UK or elsewhere, I would suggest it be reverted.

Casual changing of tags can create a lot of work for people. That is one of
the reasons why it needs to be discussed. In this case the different tag
could have been added rather than obliterate a widely used tag convention.

I would support a reversion of these edits, and ask the contributor to
consult with this list first.

Screwing the ordering of the thread up totally ...
My point to Richard was that there MAY be a valid use for a different tag. 
Richard was asking if he could change it, but part of the reason for local 
tagging differences IS because of arcane quirks ...
That is not to say that this tags is right ... there is room to clean up a 
number of the railway related tags ... just that it may be flagging a difference 
that 'abandoned' looses.


Given the amount of work now being done on additional railway information on the 
map, proper expansion of the fine detail is important.

Re: [Talk-GB] associatedParking relation

2013-05-13 Thread sk53.osm
Copied to list too.

An interesting idea, but I don't like the idea of namespacing roles:
relations are complicated enough. At the moment the access tag should do
this.

I'd like to keep the relation simple for now so am very much looking for a
convenient catch-all name for the business to which the parking relates
(actually business may do perfectly well!)

 The only thing I'm not sure about is having the role of the owning entity
 blank. Any suggestions for a name for the role. Note that the relation
 between parking owning entity is not necessarily m:1, it could be 1:m
 (e.g., take-aways sharing a car park), or even m:n.


 How about making the role indicate what use the owning entity makes of the
 parking, e.g. customers and staff (or perhaps parking:customers and
 parking:staff)?  This could be useful when the owning entity owns several
 distinct types of parking.

I don't oppose the change in principle, but we need to be clear what
you intend for all the various values. railway:historic = rail,
railway:historic = light_rail and railway:historic = tram can't all go
into one railway=dismantled tag without losing information. I expect
you intend to use another tag (dismantled = light_rail etc) but that's
worth stating.
