iso_4217

This library provides ISO 4217 active non-fund currency code lookups generated from the authoritative SIX maintenance-agency XML list together with active fund currency code lookups. It requires Unicode support from the backend Prolog compiler.

The generated fact table keeps one entry per XML row with a currency code, therefore preserving entity-specific assignments for shared currencies such as the Euro or the US Dollar. Rows marked by SIX as fund entries are exposed using the fund_currency/5 predicate while the currency/5 predicate remains scoped to non-fund entries. Minor units are represented either as integers or the atom na when the source lists N.A..
