Cshapes & Correlates of War #20
Description

country identifiers back to 1816. I think hierarchical and provenance relations can be deduced from this set. Since the Cshapes dataset which we imported earlier has these codes, the cshapes geometries might be extendable backwards in time with these listings. Or at least the PiTs without geometries can be created.
To start with I'm working on parsing this internally, but I thought I'd mention this here already. Also because with all these relations, both temporal/provenance and hierarchical, this might be a nice test case for automatic inferencing
