ROS pkg quality metrics: analysing ROS wiki pages

Running any sort of analysis on the wiki server at render time is definitely a non-starter. That content is viewed way more often than it changes.

Somewhat as a corollary the wiki is designed to be easily and openly edited without significant structure. Many of the things that are already referenced are auto generated. It might be worth exploring auto generating more of the content, rather than finding way to enforce that the content is captured in the free form wiki content.
