Hi, Sofa was (still is) an extension that was meant as a proof of concept for some crazy ideas I had. I never finished it, i might some day, but its not even working yet, so I'm not sure if there is much point in translating it.
The extension is meant to be used to generate automatically updated user-defined reports (e.g. like Special:AncientPages). Its envisioned as a replacement for DPL extension.
