Would it be a good candidate for modelling flows w.r.t economics? For instance, country 1 has currency pinned to country 2, import/exports, etc.

Maybe one could call this a "knowledge hypergraph". Datalog is very basic and everyone needs aggregations and structured data so Mangle also supports aggregations, structured data and also some function calls. When you use these it is clearly no longer datalog, but it is easy to see what part is datalog and what part is "more." To qualify this a little: Mangle does not provide much for mutability (neither the "spec" which is a bit implicit, nor the implementation) so if you want to make a real DB with inserts or an RPC interface you have to code that yourself. I find having a readable source file and running queries is good for playing around and also may cover many use cases for small DBs with static or slow changing data, or configuration.
