Hi everyone,
Here is my discussion with aliponte, as suggested by Friedrich Volkmann
I've contacted him last week end.
I've asked him before if he minds copying it here.
Thanks for making the contact with him. He is bringing up some valid
points (not that I agree to all of them). We have the line vs minor_line
distinction which is also somewhat arbitrary and the related tower vs
pole problem. These were all introduced in the early days of osm without
providing some rigid guidelines on how to distinguish them (the result
occasionally being some strange tagging). However, one difference to the
station/substation discussion is that these tags are not "incorrect" in
that they refer to correct English terms. Also trying to change
minor_line or pole would be difficult since those values have been used
literally hundreds of thousands of times. (personally I tag anything
below 50 kV as minor_line/pole).
And of course there is the line vs cable discussion but that is in a
different thread.
My pragmatic suggestion on station vs substation is to keep the
deprecation of station, advice mappers to use substation and add a
voltage tag when possible. Data consumers may treat any substation
without a voltage tag as "small". In time the larger substations will
probably be visited by interested mappers who can add voltage tags etc
(380 kV lines connecting to "small" substations should attract
attention). Data consumers should continue to support 'station' for the
time being until the use of the tag is clearly declining. One thing:
Don't perform any mass retagging of 'station'!
