XDG Specification define some directories to store information: Data, Config, Cache, Runtime. We need to figure out how to split the information we have now into this different categories.
Also see ticket:10029 for the discussion leading to this wiki.

I am writing some of the data we manage now to find it a good place. Please discuss it in devel@pidgin.im and/or change the table by yourself.
