5. Redefined Conversion Rule for the uid Property

Questa pagina riassume la sezione corrispondente di RFC 9982 e conserva i punti essenziali su JSContact, vCard e registri IANA.

The conversion rule for the Card uid property from vCard, originally in Section 2.1.1 of [RFC9555], is redefined.

Implementations that convert a vCard without a UID property to a Card of version "2.0" or higher MUST NOT generate a unique identifier as a value for the uid property.

When converting a vCard without UID to JSContact version "1.0", implementations MUST generate a value for uid. Generation is implementation-specific. Implementations SHOULD generate the same value when generating the same Card multiple times, but this still cannot prevent interoperability issues. Therefore, implementations SHOULD NOT convert to version "1.0" Card objects.
