Module lookup_data 

Lookup data for geographic, currency, and locale-based operators.

This module provides static lookup tables used by rich filter operators that require knowledge of external data (countries, currencies, timezones, etc.).

Data Structure

Lookup tables are embedded as JSON in the compiled schema metadata, enabling the runtime to perform lookups without external dependencies:

{
  "countries": {
    "US": { "continent": "North America", "regions": ["Americas"], "in_eu": false, "in_schengen": false },
    "FR": { "continent": "Europe", "regions": ["Europe"], "in_eu": true, "in_schengen": true },
    ...
  },
  "currencies": {
    "USD": { "name": "US Dollar", "symbol": "$" },
    "EUR": { "name": "Euro", "symbol": "€" },
    ...
  },
  "timezones": {
    "UTC": { "offset": 0, "dst": false },
    "EST": { "offset": -300, "dst": true },
    ...
  }
}

Lookup Operators

These operators use the lookup data at runtime:

• Country: continent, region, EU/Schengen membership
• Currency: code, symbol, decimal places
• Timezone: UTC offset, daylight saving time
• Language: language family
• Locale: language, country, script
