For me, English common sense says a 'water source' could be a river, lake,
spring etc...
the portability of water is not a measure of its source (where it comes
from) but its purity...
So I'd think the key should be
Water_purity with the key values 'potable', 'nonpotable' and 'unknown'
('yes' does not imply anything in the context of water purity nor water
source).
That key can be added to rives, lakes, drinking fountains etc etc .. no
changes are required for present tags. Simply the additional information
can be added.
Warin, I don't know if you followed the discussion and saw the proposal in
the wiki.
In short, it all started with the lack of good option to map a source of
non-potable water, like a water tap. It evolved from there to the current
state. The proposal from the last email reflects to ~90 % everything
suggested as the discussion proceeded.
I agree that water_purity sounds better than many other combinations
though. So if you could suggest how to tag a tap with non-potable water, we
can reconsider it.
Cheers,
Kotya
'We' don't have a current tag for water_tap. Which is where this
started. If it were about the portability then the subject is
missleading in both this topic and in the wiki.
As is usual the discussion considers many things associated with said
tap. Hence my comment on the tag for water purity, which could be used
for any water object, not just taps but fountains, rivers etc.
The wiki http://wiki.openstreetmap.org/wiki/Proposed_features/water_tap
now considers water purity before water tap ... ! As this discussion
looks to be too. It should have the tap as the first consideration.
The main choice for water tap is between man_made = water_tap or amenity
= water_tap. I have no firm idea on either choice. If I have too now I'd
chose man_made=water_tap. Fits with man_made=water_well .. though not
with amenity=shower and I'm certain tehre are other examples.
But the tag for the purity of the water should be named so that it
cannot be confused with some other meaning. And be secondary to the
facility .. much as 'surface=paved' is to other tags (eg highway).
So on one node the following tags
man_made=water_tap
water_purity=non-portable
-----------------------
Aside. The tag amenity=drinking_water I have used for water blubbers
commonly placed in parks for people to drink from here. They are about
waist height that provide a vertical jet of water say 6" height
controlled by a self returning mechanism. They would all be taken as
portable. Here we don't usually consider fountains to be sources of
human drinking water due to possible pollution (e.g. bird droppings,
ducks etc).
