This is a good overview on how to structure a particular page, but what about the structure of overall documentation? I've actually found several good articles about writing articles, but little about organizing many of them.

I find that most documentation that goes into a wiki, e.g., Confluence, begins and ends life as a plan. It is then surrounded by business process clutter. And then the true gems of reports about performance analysis or other details just get buried.

What would this be even called? Taxonomy? I sometimes wonder if I could convince people to call wikis, google docs, etc, a "library" and we should have a librarian go organize everything. Because it's a little sad how much knowledge just gets lost.
