This model is going to be directly based on ISO 3166-1, ISO 3166-2 and M-49 data sets, with addition of private-use cases from CLDR (like QO and its relationship) for compatibility.
Model
The single Territory model will represent all levels of world/country regions, including:
Country Groupings
The World
Continents
Subcontinents
Other Groupings (like EU and Latin America)
Countries (ISO 3166-1)
Independent / sovereign states
Dependent Territories
Country Subdivisions (ISO 3166-2)
Tree-like hierarchy
Zero, one or more levels
This will be similar to the region part of BCP-47 codes, plus the Subdivision (sd) Unicode extension to it.
Data
We need proper data sources to build this. The data sources should be kept up-to-date in sync with their source Registration/Maintenance Authorities (and not based on a software release schedule), and the compiled data should be kept up-to-date as well with clear logic and automated updates.
