Proposal talk:Fire Hydrant Extensions (part 3)
Reference of wrench
Resolved: Are pentagonal, square, triangular, linear the only possible valid values of wrench=*?
I would add a key or lock value for key lockable hydrants. Fanfouer (talk) 19:55, 4 August 2017 (UTC)
- If you find other types of wrench (e.g. hexagonal) add them. I've listed the ones that I know.
What do you mean by key lockable hydrants? I've never seen them. --Viking81 (talk) 17:19, 5 August 2017 (UTC)
check_date -> operational_status:date
The proposal describes check_date=* as "date of the last functional check". This is in contradiction to the normal use of the tag, namely the date when a mapper checked that the feature existed.
- operational_status:date=YYYY-MM-DD, as proposed by Marc on tagging mailing list, seems more specific:

Pumps
We don't need a detailed description for pumps, we need only to know if there is a pump connected (or inside) the water reserve and if it is electrical or water driven.
All other pump details can be developed in a separate proposal by someone else if he/she has reasons to do that.
Key pump already exists for water wells: [1], [2]
Values for our use can be pump=yes or pump=powered.
Also pump:type already exists, but if you think it is too generic, we can introduce pump:driven_by=electricity/water.
pump:power_medium sounds less clear to me: what do you think?

- pump:source would follow the {tag|generator|source} system with values hydro/electrical. Some may want hydro coupling sizes or electrical ratings there too. Far too much detail for me. Warin61 (talk) 10:33, 21 December 2017 (UTC)
- pump:type I would not use for the hydrants because it is not clear which pump is in there.
- I agree to pump:power_source=* as to not confuse with the water source intake. Fanfouer (talk) 19:30, 23 December 2017 (UTC)
- I don't like pump:source=* too, because it can be confused with water_source=*.
- I have some doubts on pump:power_source=* because, as colin Smale pointed out, technically water and electricity are mediums to transfer energy, not a source. But if we go thoroughly this reasoning, a pump is electrically driven, but electricity could be produced burning coal, that has been produced by trees, that took energy from Sun, that took energy from its internal nuclear fusions... The same for a water driven pump: water can have potential energy because of its elevation, and elevation is due to the fact that water evaporates because of solar energy and then condenses in clouds that produce rain on mountains. Again solar power and ultimately nuclear fusion is the power source...
- This reasoning obviously goes far beyond our objectives and does not add useful data to OSM.
- Then or we use pump:power_source=* with a not literal meaning (but I suspect that someone will refuse this approach), or we use pump:power_medium=* that is correct but not intuitive, or we use completely different words, like pump:driven_by=* or pump:powered_by=*.
- Probably pump:powered_by=* is the best solution for me.
