osm:way (tag)
From SnapMap
osm:way = <osm way id> lets you associate a way from OpenStreetMap with an image. The tag implies part of the way is visible in the photo.
OSM ways may be edited or deleted, so using this tag is not necessarily safe long-term.
The tag format is copied from that at Flickr, which also uses OSM node and way IDs. As with Flickr, the name tag on the OSM way is parsed; it is inserted into the SnapMap search tables.
