As can been seen, there are a number of objects and attributes that use a country code.
The Frankie service will always attempt to normalise and store country information as an ISO-3166-alpha3 code, such as AUS for Australia, or GBR for Great Britain/United Kingdom.
You generally can supply full country names or -alpha2 codes, as long as they conform to ISO-3166 standards, but the service will always attempt to convert to an alpha3 code. Failure to convert the code will result in the data being rejected and an error returned.
You can find the full list of ISO-3166 country codes here:
