RFC 9982: JSContact Version 2.0: A JSON Representation of Contact Data

This document defines version "2.0" of JSContact. It defines the uid property of a Card object to be optional, rather than mandatory, as defined previously in version "1.0". All other definitions of JSContact version "1.0" remain as defined in RFC 9553. This document updates RFC 9555 by redefining how to convert the now optional uid property from and to vCard. It also registers the vCard JSCOMPS parameter at IANA, which was defined but not registered in RFC 9555.
