About two years ago I introduced the taginfo “projects” feature: A way to connect taginfo with all the uses of OSM tags out there, to editors, special maps, routing services etc. By now we have about 50 projects that have published a project file describing their tag use. This data gets integrated into taginfo and helps mappers and users of OSM data to see who actually uses which tags. Today I have released some changes to taginfo that integrate this information even better.
