RFC 9982 - JSContact Version 2.0: 連絡先データの JSON 表現

• Status: Proposed Standard
• Published: May 2026
• Stream: IETF
• Updates: RFC 9555

Abstract

This document defines version "2.0" of JSContact. It makes the uid property of a Card object optional rather than mandatory, while all other JSContact version "1.0" definitions remain as defined in RFC 9553. It updates RFC 9555 by redefining conversion of the now optional uid property from and to vCard, and it registers the vCard JSCOMPS parameter at IANA.
