Good idea! What I'm concerned you can pull request this. I will also need a good addition to README.md then :)
TODO
[ ] add a first stops.csv which contains a platform per row
[ ] explain the set up of stops.csv in a new section in the readme.md
[ ] communicate about the fact that we need to crowdsource this list (through issues and pull requests. E.g., we can also ask the OSM-BE community to contribute
[ ] Make sure this list can be used to create the linked data (there's already a nodejs script in here), and is also used as an input to the GTFS zip file
I suggest we add a stops.csv that contains all the platforms with their own URI (= parent_station URI#platformNumber), latitude and longitude.
This way we can crowdsource the locations of these platforms.
