database.pod - documentation for the Locale::Object database
The database of locale information used by the Locale::Object modules uses DBD::SQLite, and contains several tables.
CREATE TABLE country ( code_alpha2 char(2), code_alpha3 char(3), code_numeric smallint, name char(100), dialing_code smallint, utc_offset_main char(5), utc_offsets_all char(50), PRIMARY KEY (code_alpha2) );
code_alpha2 , code_alpha3, code_numeric and name are data from ISO 3166 - see http://ftp.ics.uci.edu/pub/ietf/http/related/iso3166.txt.
code_alpha2
code_alpha3
code_numeric
name
dialing_code is an International Direct Dialing code - see http://kropla.com/dialcode.htm.
dialing_code
utc_offset_main is the time offset of the time zone of the country's capital from UTC, expressed decimally in hours. utc_offsets_all is a comma-separated list of offsets for all time zones that the country falls across, listed from west to east. If there is only one value this will match utc_offset_main.

utc_offsets_all
CREATE TABLE currency ( country_code char(2), name char(100), code char(3), code_numeric smallint, symbol char(20), subunit char(100), subunit_amount smallint, PRIMARY KEY (country_code) );
country_code contains ISO 3166 two-letter country codes, as in the previous table.
country_code
name and code contain ISO 4217 three-letter codes and names for world currencies - see http://fx.sauder.ubc.ca/iso4217.html.
code
symbol, subunit and subunit_amount contain currency symbols, subunits (such as cents) and the amounts of subunits that comprise a single currency unit (such as 100 [cents in a dollar]). This data was sourced from http://fx.sauder.ubc.ca/currency_table.html.

CREATE TABLE continent ( country_code char(2), name char(13), PRIMARY KEY (country_code) );
CREATE TABLE language ( code_alpha2 char(2), code_alpha3 char(3), name char(100), PRIMARY KEY (code_alpha2) );
code_alpha2 contains 2-letter ISO 639-1 language codes. See http://www.loc.gov/standards/iso639-2/englangn.html.
code_alpha3 contains 3-letter ISO 639-2. There two parts of ISO 639-2, B (for 'bibliographic') and T (for 'terminology'), which differ in 23 instances out of the full list of 464 codes. For simplicity, this module uses the ISO 639-2/T versions. For more information, see the URL above and also http://www.loc.gov/standards/iso639-2/develop.html.
name contains the standard names of languages in English as defined by ISO 639.
CREATE TABLE language_mappings ( id char(4), country char(2), language char(3), official boolean, PRIMARY KEY (id) );
An example section of this table:
ID COUNTRY LANGUAGE OFFICIAL at_0 at ger true at_1 at slv false at_2 at hrv false at_3 at hun false
What this tells us is that in Austria, four languages are spoken: German, Slovenian, Croatian (Hrvatska) and Hungarian, and that only German is an official language of Austria. The mappings are ranked in order of prevalence of language, official languages first, followed by non-official. Please note that this is approximate at best.
My original source for the language-country mappings was http://www.infoplease.com/ipa/A0855611.html. However, there is no clear origin for this list, which occurs in several places on the Web, and it required some serious rationalization before data was able to be usefully extracted for it.
In addition to the preceding, the following sources were invaluable:
Nationmaster - http://www.nationmaster.com/
Ethnologue - http://www.ethnologue.com/

CREATE TABLE timezone ( country_code char(2), timezone char(50), is_default boolean );
COUNTRY_CODE TIMEZONE IS_DEFAULT br America/Recife false br America/Fortaleza false br America/Belem false br America/Noronha true
country_code contains ISO 3166 two-letter country codes.
timezone contains time zone names as defined in the Olson database. See http://www.twinsun.com/tz/tz-link.htm for more than you ever wanted to know about this.
timezone
is_default contains a boolean value indicating whether the time zone in question is default in the country. For countries with more than one time zone, a value of 'true' indicates the time zone covers the nation's capital.
is_default
The data for this table was sourced from http://s.keim.free.fr/tz/tznames/.
