Hi Brandon, thanks for the explanation, but wouldn't it be easier to just analyse edit summaries? If you edit by section the edit summary defaults to start with the section heading.......

(This may not be 100% accurate; the person who knows most aboutthis is on vacation, but I'll try to explain to the best of my understanding.)
Those weird URLs are part of a clicktracking process. It's a testto see how people go about editing the page *most often* (by section, or by edit tab) and further to see how effective various calls-to-action (such as those given by Article Feedback) are.
The longevity of the data isn't something I can comment to but I'dbe surprised if it lasted even 3 months. I do not know if there are identity markers connected to them but I wouldn't be surprised.
To that end, the data is only useful in roll-ups, and wouldn't besomething published anywhere except in aggregate.

MZ is correct: 3 months is the purge for Checkuser data.
As to the rest of it, Diederick van Liere, our resident guru of data,
will
be checking into this, and will confirm back when we know exactly wht is intended by the devs for that data. I will say that generally speaking, the Foundation prefers to maintain the minimum data possible for the shortest period of time.

The exact time is confidential.
Err, no, I don't think so. It's not defined in the files at http://noc.wikimedia.org/conf/, which means it should be using the default, as defined at <
http://svn.wikimedia.org/viewvc/mediawiki/trunk/extensions/CheckUser/CheckU
ser.php?revision=106556&view=markup>. From that file:
# How long to keep CU data? $wgCUDMaxAge = 3 * 30 * 24 * 3600; // 3 months
The last attempt to change this value (without community discussion) was summarily shot down: <http://svn.wikimedia.org/viewvc/mediawiki?view=revision&revision=40847
.
That's only CheckUser data, though. I'm not sure what David wants
confirmed
from the Wikimedia Foundation. Different data has different expiries. A
lot
of it is permanent (e.g., revisions aren't going anywhere for the most part). I guess the question is specific to the ClickTracking extension: https://www.mediawiki.org/wiki/Extension:ClickTracking?
