Membership Model Visualization

The newly proposed PSF membership model is a great idea and the echo from the PSF members is overwhelmingly positive.

There are quite a few details. A picture may help to make these easier to understand. This is an attempt to visualize this. Instead of using a graphics drawing application, I generated the diagram below with a Python program. The source is also attached.

So, just where does "the diagram below" appear? - SH

This is by no means complete but can serve as a basis for coming up with further details. The advantage is that all these familiar tools and procedures such as version control, pull request and tests can be applied.

So far there is no code in methods. It should be possible to add algorithms and make the membership rules executable. Since code is primarily a means of communication between humans and only in the second place instructions for the computer, this little program may help to better understand what we want to express.
