Forgive me if I'm misunderstanding but wouldn't a set up like this (even
anonimized as described above) allow someone to recover the location of an
individual editor on sparsely edited wiki's?
If we're just looking to provide a convenient lookup for IP editors what is
the advantage of doing this over requiring researchers to use publicly
available IP databases to perform geolocation?

We have been discussing adding new geo data for a long time. ****
I lost track of current status and latest decisions but FWIW a year ago
this was the idea for squid log: ****

We thought of replacing ip address by a composite field (using a different
delimiter than the field delimiter).****
The field could look like this:****
** **
4|hash code|CL||Santiago|-33.5,-70.5****
6|hash code|US|CA|San Francisco|-37.5,122.5****

Where 4 or 6 is the #triplets in ip address. ****
Hash code is anonimized ip address. ****
Country code as used by MaxMind (

Region/state when available or else empty string (*)****
City name when available or else empty string (
http://www.maxmind.com/GeoIPCity-534-Location.csv )****
Lastly follow latitude/longitude, rounded on purpose. This gives
resolution of at best 55 km or 30 mi resolution, depending on latitude, to
ensure anonimization particularly for edits. Otherwise a very active editor
in a sparsely populated region of say China could easily be matched with
edit timestamps from dumps. ****

* Caveat: ****
Supplying region code requires 'external lookup' as MaxMind puts it. (
http://www.maxmind.com/en/city )****
This is probably a costly operation. ****

Hi James,****

We can take a look at this -- the next step for WikiMetrics is to expand
the reporting capabilities. The developer with the most context is out
until Wednesday; we should be able to get back to you by the end of the
week with an estimate of how difficult it would be to implement this
changes.****

Will that work?****

Greetings,
I am James Hare, president of the Washington, DC chapter. At Wikimania I
have been learning about the editor retention data the Wikimedia Foundation
has been collecting and analyzing. I was discussing it with Ryan Kaldari
and he noted that while the data was available at the national level, it
was not yet available at the state level.
How difficult would it be to implement state-level analysis? Would it just
be a matter of simply changing the geolocation lookup code, or would it be
a very expensive change that would benefit relatively few people? For
Wikimedia DC's sake I am interested in data for the District of Columbia,
Maryland, Delaware, Virginia, and West Virginia (our defined chapter
region).
Regards,
James Hare
