Diagrams and design patterns

I’m doing a small study on software design patterns in Blender modules. For easy location of these it is often helpful if the documentation includes UML diagrams or some kind of diagram that determines the connection between classes.
Anyway, inspecting the code I have been able to find several patterns, but I think that with diagrams I would have found some more complex ones.
With this post I would like to know if there is any place that contains these diagrams, or if there is any plan for the realization of these.

try wiki.blender.org, there’s a code documentation page.
