IB20Asset.sol
Description
Returns the value of the named metadata entry, or the empty string if no entry exists for that key. Each Asset token carries an arbitrary key/value store the issuer can use freely — for example"category" → "electronics", "region" → "north-america", or "reference" → "REF-2024-001". All entries are optional and added post-creation; the factory seeds none at token creation.
