Relation to station identifiers used in SNCF tickets?

SNCF ticket barcodes contain station codes in this format too, however they seem to have a slightly broader scope (or rather, this property seems to be a strict subset of what can be found in SNCF tickets):

• There are codes for stations beyond what the formatter URL for this property can handle, see e.g. https://ressources.data.sncf.com/explore/dataset/referentiel-gares-voyageurs/table/?sort=gare_alias_libelle_noncontraint (which has the codes without the FR country prefix).
• There are international codes in those tickets as well, e.g. "CHGVA" for Geneva or "ESBST" for Barcelona, see also https://github.com/trainline-eu/stations/blob/master/stations.csv (sncf_id column).
• These codes are typically written in upper case (but that's really a minor difference).

How should this be handled, by relaxing the constraints on this property, or by adding a new property? Volker.krause (talk) 17:47, 13 February 2020 (UTC)

Hi, this property are only to be used with the formater url https://www.garesetconnexions.sncf/fr/gare/$1 , on https://ressources.data.sncf.com/ they don't have this id and CHGVA and ESBST don't work, upper or lower.

So to use it we would have to create another property (but with which url ?) — eru ^{[Talk] [french wiki]} 18:19, 13 February 2020 (UTC)

Thanks, makes sense. I am not aware of a formatter URL for the SNCF IDs (nor the very similar Benerail ones) unfortunately, I mainly need this to map from ticket data containing those ids to the station items. I'll look into proposing new properties then. Volker.krause (talk) 19:53, 13 February 2020 (UTC)
