As I write in my profile, I was really peeved off, that dozens of “Camino Apps” (apps used to track users along the Ways of St. James, the Caminos de Santiago) did ask their users for updates to opening hours or bed counts in albergues, but never contributed back to OSM what they’d discovered.

I launched a “test balloon” in 2023, renaming an accommodation to reflect its real name, and lo and behold, of the 23 apps I checked, 22 had suddenly also changed the name, meaning they used OSM data, but didn’t ever give back to the community.

So I changed it, wrote a Camino App that did contribute back. We don’t expect our users to have OSM accounts. Instead, we recruited a bunch of volunteers, who are served the changes, check them personally, and then contribute them back to OSM.

First step: fountain potability. Along the Caminos are thousands of fountains providing drinking water to the 500k pilgrims walking the Way every year. Spain is excellent, when it comes to drinking water quality, but sometimes fountains dry out, become undrinkable, or become drinkable again. Nothing sucks more than going 1000m out of your way to find out that fountain has been closed.

I’ll semi-manually start updating fountain “drinking_water=” tags over the next 30 days along the most famous route, the Camino Francés. Once that’s stable and enough volunteers have been trained and shown that they can do this without harming the dataset, we’ll expand to hostel data.
