Weird, thought we had a canon policy, but I guess not.

In my opinion anything contrived by the author should take priority. Generally speaking, the tankoban releases are also considered the "correct versions", as their formatted to include/fix info the author hadn't had time to review during the initial release. I believe this is how the Japanese community, and most anime wikis regard it. Imo, the list should be ordered like: Tanks -> Jump Release -> Artbooks -> Author -> Spin-Off - > Novels -> Anime -> everything else. Of course, this kind of depends on the release date of the information relative to other sources.

I can't quite imagine the standard the Doctor Who wiki seems to be using though, do you have an example?
