Here’s a question for living museums, old charge signs and OpenHistoricalMap: how should we describe charge=* or charge:conditional=* for fee tables that use the old pounds, shillings and pence, like the one below?
I am thinking of charge=£0:0:2.5 based on the charge for sheep, lambs, and hogs per 20, accounting for the fact that we did not have ISO 4217 codes until 1978. Converting to a modern equivalent value would be lossy, since dividing anything other than multiples of three old pence (= 0.0125 new pence) would result in recurring decimals (e.g. 1 old pence = 0.0041666… new pence).
Looks like there were a number of conventional notations. If you’re mapping this in OpenHistoricalMap, don’t worry so much about the machine readability of keys such as charge=* before decimalisation and phone=* before automation. We’ll figure out a systematic representation if the key ever becomes common enough. That said, I would intuitively expect some kind of compound measurement, similar to the one holdover in OSM: maxheight=8'5".
Maybe some of the British mappers on the OHM forum have more ideas.
My gut instinct is that I’d generally expect a / between values for shillings (s) and pence (d) as that’s what I’ve seen most on preserved signs, posters &c.
Might be best to include a trailing d to emphasise that it’s not in new pence.
