Do not use the name tag. If you must, possibly use the tag
"description=*"?
The problem is on GPS side.
Viking explained the GPS he use only take POI with a name field
without additional attributes.
Then it's harder to distinguish presurized hydrants vs suction points
but not impossible : concatenate water_source with ref or arbitrary
label (hydrants don't usually have names) and you're done.
Rendering/use issue.
All the maps will use the name tag to display that information .. even
if they don't want it?
If Viking needs a POI file derived from OSM then that derivation can
combine the description into the name value.
Pipe lines would also have a flow_capacity, as would canals, drains.
Humm pipeline uses the tag capacity ... I don't think that is a
good fit with present OSM use of that tag.
In the interests of having a more universally applied tag I'd
rather have a tag "flow_capacity=*" as a property tag much like
length, height etc.
+1 on idea
Capacity is used several hunder thousand times but flow_capacity never
(fire_hydrant:flow_capacity about 7k).
Since capacity definition is "The tag describes the capacity a
facility is suitable for", it can fit for pipelines, hydrant, canals,
drains... in m3/s or m3/h, can't you ?
The values of capacity are typically a single number - 2, 4, 10 etc They
mostly reflect the number of car parking spaces available. So it is a
unit less number - not l/h or m^3/s etc.
fire_hydrant:flow_capacity has over 6,000 uses ... distribution is
mostly Europe .. no wiki page as yet, needs one to state default units
as most of the values have no units, only some have l/min etc.
