Standard Places Response (SPR)

The "Standard Places Response" (or SPR) is an on-going effort to standardize on a minimum set of properties that Who's On First related services should return when queried.

The SPR is being used by a lot of the software packages written in Go and assumes an interface (contract) that looks like this:

type StandardPlacesResult interface {
	Id() string
	ParentId() string
	Name() string
	Placetype() string
	Country() string
	Repo() string
	Path() string
	URI() string
	Latitude() float64
	Longitude() float64
	MinLatitude() float64
	MinLongitude() float64
	MaxLatitude() float64
	MaxLongitude() float64
	IsCurrent() flags.ExistentialFlag
	IsCeased() flags.ExistentialFlag
	IsDeprecated() flags.ExistentialFlag
	IsSuperseded() flags.ExistentialFlag
	IsSuperseding() flags.ExistentialFlag
	SupersededBy() []int64
	Supersedes() []int64
}

And this is what looks like to a user doing a point-in-polygon query against the go-whosonfirst-pip-v2 tool:

curl -s 'http://localhost:8080/?latitude=37.787221&longitude=-122.400098&placetype=locality' | python -mjson.tool
