Go tools for working with libpostal (sometimes in the service of Who's On First)

Install

Make sure you have Go and libpostal installed. Then

make bin

wof-libpostal-server

$> ./bin/wof-libpostal-server -options

Usage of wof-libpostal-server:
  -gracehttp.log
	Enable logging. (default true)
  -host string
    	The hostname to listen for requests on (default "localhost")
  -port int
    	The port number to listen for requests on (default 8080)

Note you will need to install the underlying libpostal C library yourself in order for wof-libpostal-server to work.

wof-libpostal-server exposes the following endpoints:

Endpoints

GET /expand ?address=ADDRESS

This endpoint accepts a single address parameter and expands it into one or more normalized forms suitable for geocoder queries.

curl -s -X GET 'http://localhost:8080/expand?address=475+Sansome+St+San+Francisco+CA' | python -mjson.tool
[

]

GET /parse ?address=ADDRESS

This endpoint accepts a single address parameter and parses it in to its components.

curl -s -X GET 'http://localhost:8080/parse?address=475+Sansome+St+San+Francisco+CA' | python -mjson.tool

    {
        "label": "house_number",
