This repository is a daily cache of Google’s Address Data Service, which is used by libaddressinput. The files contain machine-readable specifications for address data. The specifications seem to be heuristics rather than comprehensive and precise restrictions.
For ease of comparison, all of the keys in each JSON file are sorted alphabetically by the caching script. The Google service doesn’t seem to use a consistent order. So, this isn’t a completely faithful cache of the service if, for some reason, you need the exact order of the keys from Google’s service.
At one point, there was a request to make this data available as part of Unicode’s Common Locale Data Repository (CLDR), but that doesn’t appear to have occured.
Contributions to the non-data portions of this repository are welcome via issues and pull requests are welcome. For the data portions, please use the libaddressinput repository.
Approximately once per day, around noon UTC, the script update.sh is run, and this repository is updated.
This repository tracks the latest data at https://chromium-i18n.appspot.com/ssl-address. The deprecated, older address (https://i18napis.appspot.com/address) is not tracked.
I make no claims whatsoever on this data. Lara Scheidegger from Google commented to someone else:
We don’t have an official license for it; it comes mostly from IPU and other general research, there are no restrictions on it that anyone involved with it knows about it...
