Hierarchy of address keys

Hi, I need a full hierarchy of all address keys.

In https://wiki.openstreetmap.org/wiki/Nominatim#Hierarchy few keys only present in the hierarchy.

EDIT: I need to exactly know the tag or key names associated with each of the subdivision values present here : https://wiki.openstreetmap.org/wiki/Tag:boundary=administrative#10_admin_level_values_for_specific_countries

Do you mean you need a reverse geo-coding engine that returns "all" address keys? Or?

Naturally "all" address keys are rarely in use in the real world, so most of the time most of them are going to be empty see https://wiki.openstreetmap.org/wiki/Key:addr

Address formats vary by country. Do you have any country/ies in mind?

I need the hierarchy of 'all' possible addres keys. For example to below address i hope the hierarchy is countrycode>country>postalcode>state>state_district>hamlet>city_district>suburb>neighbourhood>road

  "road":"3rd Street",
  "neighbourhood":"F Block",
  "suburb":"Ward 101",
  "city_district":"Zone 8 Anna Nagar",
  "hamlet":"Kaveri Rangan Colony",
  "state_district":"Chennai district",
  "state":"Tamil Nadu",
  "postcode":"600102",
  "country":"India",
  "country_code":"in"

@rorym: I need to create the hierarchy for all countries, is there a generic way possible ? Or is there a meta-admin-level info based on country, i.e the sub-divisions address keys to a country ?
