This document specifies a descriptive framework for a city including an associated foundational ontology of the anatomical structure of a city or community. The descriptive framework is intended to have the following qualities:
-- timeless, i.e. compatible with any human settlement at any time in history;
-- acultural, i.e. valid for any culture and any type of city;
-- scalable, i.e. valid for a metropolis, a city, a small town or a village;
-- generic, so that everything we could define as a human settlement, such as a smart city, has a place in this structure.
