Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Let an agent explain Italian administrative geography by level, identify which authority covers a place, and link to official codes and boundary data.

Any administrative division of Italy, including the 20 regions, provinces and metropolitan cities, municipalities (comuni), municipal subdivisions such as circoscrizioni, quartieri and zones, and the autonomous provinces; the system is set by the Constitution and regional and municipal law, with codes maintained by the national statistics institute.

What it is for: Local government, statistics and addressing in Italy.

It can be identify the region, province and comune of a place; explain tiers and their competences; find ISTAT codes and boundaries; trace reforms such as metropolitan cities.
