The country sits in the middle. Around it: the ground and the places, then the organisations, then the instruments that govern them, then the events on the record. A record’s ring is decided by what kind of thing it is, so the reading is the same on every group.
A link whose validity window has closed is drawn dashed and stays on the map. An expired title or a former operator is a finding, not noise.
Relationships crossing out of this group, gathered by where they land.
The nodes above, as a list. Each one opens the record’s own page, with its relationships and the source passage behind each of them.
