[RFC] Adding Page ID as a valid and preferred way to link to Wikimedia Commons

I’m curious why you haven’t proposed to allow multiple File: or Category: references by separating them with a semicolon ;? To me that sounds like the logical conclusion of “allow multiple links” and “use human-readable file names”?

Like this:

wikimedia_commons = File:Gare nord pelle.png;File:GareduNord vue.png

I’m aware this would also mean more work for data consumers and create problems because semicolons may appear in file names. But it would be in line with the typical use of semicolons for multiple values in OSM, no?

It seems to be tagged like this already in some places: overpass turbo

Mainly because semicolons are a valid character in Commons titles so it could break incorrectly by using that delimiter with titles

There’s a rarely used, lightly supported ;; escape sequence for semicolons in semicolon-delimited keys. These 28 elements containing literal semicolons in titles could be retagged to avoid confusion with these 619 elements that link to multiple files and/or categories without using the escape sequence.
