Re: [Tagging] Intermittent highways?

2020-07-16 Thread Jez Nicholson
I believe there was a recent discussion on showgrounds and temporal events.
"temporal" as opposed to "temporary" as in "happens regularly every
week/month/year for a set period of time at the same location". Up until
recently, OSM has been strongly against temporal objects, but German
Christmas markets have slipped through and the world has not ended.
Personally, I would be interested in having temporal features such as
Glastonbury Festival as it would make the map more usable for the general
public and be a differentiator against other maps. However, I hope that
people are careful because this opens the floodgates for weekly food
markets, pop-up food vans, etc.

I would not use opening_hours tag to represent the temporary existence 
of ways if this should mean that the ways are only there some weeks of 
the year.


If the thing is permanently scheduled event then it is not a temporary 
event.


Temporary: Lasting for only a limited period of time; not permanent.

Opening hours have no restriction to being more or less than some 
proportion of a year.



Similarly, access is about legal access and not physical existence. 
With the established schemes, you could use conditional on the 
highway, like highway:conditional=footway/service/path @ Time

it is not common, but someone else already had this idea as well:

As you say - not common and probably not rendered/used by any application.

I would not use opening_hours tag to represent the temporary existence of ways 
if this should mean that the ways are only there some weeks of the year. 
Similarly, access is about legal access and not physical existence. With the 
established schemes, you could use conditional on the highway, like 
highway:conditional=footway/service/path @ Time

I think you're looking for conditional access.  For example, every year in
the fall, 3rd Street next to the BOK Center is regularly closed to motor
vehicles and converted to a festival space complete with ice skating rink.

I too would suggest opening_hours.

Seasonal is related to the climate and the climate does vary from one 
year to the next and may be why the tag has a 'loose description'. An 
annual festival is not usually held for an entire climatic season, so I 
would not use it for them. Similar argument with intermittent with the 
added argument that it is not water related.

non-waterway features, and depending on how much one wishes to stretch 
the definition of "season" (which is already a pretty loose concept, 
even on OSM), it could maybe be used here too?

Does it make sense to map such paths, perhaps borrowing the 
"intermittent" tag from waterway tagging?

[Tagging] Intermittent highways?

2020-07-14 Thread John Sturdy
I've been adding some detail to a site that is used annually for a festival
(not happening this year because of Covid-19), where there are paths in the
same place year after year, but the paths are not there when the festival
is not happening, although increased wear on the ground around them is
probably visible much of the time.

Does it make sense to map such paths, perhaps borrowing the "intermittent"
tag from waterway tagging?
