Circular economy as focus for VF?
I am thinking about @pmackay 's and @djwesto 's work with the circular economy. I like focusing on these use cases because 1) I think that's where we need to go in all economic work ultimately; and 2) it will challenge the model to be as complete as possible because it creates cycles, which are more difficult to work with in directed graphs. ( @bhaugen has more experience in dealing with cycles in the logic of following value flows, so he can explain this better than I can, if needed.)
So this issue is to start a discussion / brainstorming / get people's thoughts.
And at some point (if you're willing, Paul and Chris), I'd be very interested to hear more about what you have going in your local work and if/how it might make sense to use that in developing VF, and if that VF work can help develop what you are doing now. (I know you are trying to figure that out, and I feel like I haven't understood enough to be necessarily on target. And I haven't even looked at what you have in code now, which I am willing to do if it would be helpful and if you can give some direction into the code. And no worries if this is premature or otherwise unwelcome, let us know and I'll back off!)
