Model
The estate model in one place — the record, the act, subjects & events, the data model, the doors register, the chassis, and the architecture.
The Reference section shows the catalog as pages; this section shows the model the catalog is written in. Everything here is either the doctrine of the estate (the record, the act, subjects) or a generated register over the same rows that answer the wire (data model, events, doors).
