  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).
