Ah, I see - you mentioned tagging, so I thought it's purely about data that fits in OSM.
Sounds like utilising the mapped infra in OSM and building on top of it with custom attributes might work - maybe @brunspeteris has some hints? :)
https://facilmap.org has some collaborative map functionality, but haven't used it myself, barely found it from some bits and pieces in memory.
@richlv @thibaultmol @MapComplete @brunspeteris Thanks for the facilmap link, looks interesting (and hard to find :)
Technically that's what I'm planning, as you say: extract all the footways and cycleways (and lanes) from OSM, split by intersections, upload into a cloud GIS and add classifying/commenting with forms, available through a mobile app.
