I think this is good and I have no intention of changing this thing in fact.
That’s why we decided some years ago to record additional detail about the
structure in the fountain tag.
I wish to add more sense to how these structures are described. The
current tagging scheme has a lot of problems with overlapping tags.
drinking_fountain (which is somehow a duplicate of fountain=drinking ...)
man_made=drinking_fountain is an exact duplicate of fountain=bubbler;
there is no reason for having two equivalent tags at all.
All of these can already be described, although there could (should IMHO) be
more properties for the details, for example:
Agreed, what I'm most interested in, however, is making sense of the
main tags used; not the specific descriptive values.
I give precedence to fountains over taps, for a drinking fountain you could add
tap=yes or no, in case of a bigger fountain you would tag the tap as its own
object.
If you use man_made=water_tap both to describe single taps of a large
fountain and the fountain as a whole, then the tag has a double meaning
and it's unclear what it is describing when you see it on the map.
I believe our tagging scheme for drinking water is following general interest
here.
Yes, the main interest is knowing where to find drinking water, that
works very well.
What doesn't work is the description of what is delivering the water.
The example from Enno cannot be described unequivocally in a single way,
it can be described in many different ways each missing out on something.
I'm not saying that this tagging scheme has to become the norm for
tagging drinking water, I'm saying that since the option is there to tag
drinking water places in more detail, then this scheme should make sense
and account for all (at least most) cases in a simple and understandable
way.
These features are not so widespread; thus the change or deprecation of
one of them shouldn't be a big problem.
You must also realize that this scheme is probably generating a lot of
mistags, since I imagine a lot of people are tagging drinking fountains
as amenity=fountain (that is what I would do and what would appear to me
as most sensible before reading 10 different wiki pages).
