http://qudt.org/schema/qudt/DigitalCurrencyUnit
A currency-like unit for cryptographic or tokenized assets. Instances should reference an ISO 24165 Digital Token Identifier (DTI) when available.
Focus nodes of this shape (qudt:DigitalCurrencyUnit) can have the following properties:
| PROPERTY | DESCRIPTION | MIN | MAX | VALUE TYPE | OTHER CONSTRAINTS |
|---|---|---|---|---|---|
| qudt:blockchainNetwork | Primary network name (e.g., 'Bitcoin Mainnet', 'Ethereum Mainnet'). sh:message blockchainNetwork, if provided, must be a single string (e.g., 'Bitcoin Mainnet'). |
0 | 1 | xsd:string | |
| qudt:currencyCode | Alphabetic Currency Code as defined by ISO 4217. For example, the currency code for the US dollar is USD. sh:message currencyCode must be a single 2–10 character uppercase alphanumeric mnemonic (e.g., 'BTC', 'USDT'). |
0 | 1 | xsd:string |
sh:pattern
^[A-Z0-9]{2,10}$
|
| qudt:currencyExponent |
The currency exponent indicates the number of decimal places between a major currency unit and its minor currency unit.
For example, the US dollar is the major currency unit of the United States, and the US cent is the minor currency unit. Since one cent is 1/100 of a dollar, the US dollar has a currency exponent of 2.
However, the Japanese Yen has no minor currency units, so the yen has a currency exponent of 0.
sh:message currencyExponent must be a single integer between 0 and 30 (e.g., BTC = 8, ETH = 18). |
0 | 1 | xsd:integer |
sh:minInclusive
0
sh:maxInclusive
30
|
| qudt:hasDTICode | ISO 24165 Digital Token Identifier (12-character alphanumeric). sh:message hasDTICode, if provided, must be a 12-character ISO 24165 DTI (A–Z, 0–9). |
0 | 1 | xsd:string |
sh:pattern
^[A-Z0-9]{12}$
