  1. Who’s On First The open gazetteer from Mapzen whosonfirst.mapzen.com Nathaniel

  2. Mapzen is building a gazetteer of places. Not quite all

    the places in the world but a whole lot of them and, we hope, the kinds of places that we mostly share in common. A gazetteer is a big list of places, each with a stable identifier and some number of descriptive properties about that location. An interesting way to think about a gazetteer is to consider it as the space where debate about a place is managed but not decided. We call our gazetteer “Who’s On First” (or sometimes “WOF” for short).
