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 identify the meaning of wilaya in a given country and period, explain the term and its variants, relay hierarchy, counts and codes from official sources, and keep historical, current and adopted uses distinct.

An administrative division used in Arabic-speaking and formerly Ottoman or Persian-influenced countries, from the Arabic word for governance, denoting a province, governorate or district; wilayas are the provinces of Algeria, Mauritania and Oman, governorates in Tunisia and elsewhere, the vilayets of the Ottoman Empire, the velayats of Turkmenistan and Iranian usage, and by adoption the districts of Tanzania and Kenya, and historically the provinces of the Umayyad and later caliphates.

What it is for: Naming a level of administration in many countries.

It can be identify the meaning in a given country; explain the term and variants; relay counts and codes; distinguish historical from current uses.
