Yes - we have worked with Peter on building the Seshat Databank of world history. His work on modelling long term dynamic processes is great - definitely worth reading any of his stuff.
aha - don't mention the war - I'm in the process of completing a release of the Seshat dataset with a TerminusDB tutorial on how to build it into a graph and query it. But I keep getting distracted when I'm just about finished. Thanks for the interest thought - it will encourage me to get it finished!
