This is a very simple database with a web interface that records all username changes in OpenStreetMap.
There is a parse_osc.pl
script. If you run it with -c
key, it will create
a table in a specified database. To populate that database, you would need
to parse every replication diff since the dawn of the OSM (the latest changeset
dump won't do: it contains only the latest user names). After that just
set up hourly replication. Parameters of the script are identical to the
similar named one in WHODIDIT project.
You can download database backup here.
Number in the file name denotes sequence index which you should put into
state.txt
when using hourly updates. This file is updated very seldom:
replication diffs are processed very fast, so there's no need.
There is an API at http://textual.ru/whosthat/whosthat.php
. It returns JSON
or JSONP (if you specify jsonp=<name>
parameter). It has following actions:
action=last
: returns the last username for specified users. It's an array of strings.action=names
: returns all names for specified users, sorted by date. It's an array of hashes:id
for user id andnames
for an array of user names.action=info
: returns detailed information on name changes for specidied users. It's an array of hashes:id
andnames
, the latter contains array of hashes withname
for user name,first
for the first spotted usage in database andlast
for the last one.action=recent
: returns 15 last renamings. It's an array of hashes withid
,date
,from
andto
keys.
To specify users, use one of those parameters:
id=<user_id>
: query by user id.name=<user_name>
: query by user name. Note that there can be several matches.q=<query_string>
: search all users whose name matches the query string.
