        This document defines a set of new properties for vCard and extends the use of existing ones. Their primary purpose is to align the same set of features between the JSContact and vCard formats, but the new definitions also aim to be useful within just the vCard format.  This document updates RFC 6350 (vCard). ("vCard Format Specification").

      <t>
        The JSContact <xref target="I-D.ietf-calext-jscontact"/> target="RFC9553"/> format aims to be an alternative to the
        vCard <xref target="RFC6350"/> format for representation of contact and address book
        data.  As such, it introduces new semantics that are not covered in the current
        definition of vCard and its various extensions.  Converting contact data between
        the two formats is defined in <xref target="I-D.ietf-calext-jscontact-vcard"/> target="RFC9555"/> with the goal of
        not losing any semantics during conversion. To do so, achieve this, this document
        defines a new set of properties for vCard and extends existing definitions.

        <t>This specification modifies the definition of the "ADR" ADR property.

        <t>This specification modifies the definition of the "N" N property.  It extends its structured value with additional name components to better support international names and generation markers.  Doing  In doing so, this also facilitates formatting N property values using the <xref target="CLDRPersonName">Unicode CLDR Unicode Common Locale Data Repository (CLDR) Person Name</xref> Name <xref target="CLDRPersonName"/> formatting standard.</t>
        <t>One new component is for secondary surnames, as because in some cultures, such secondary surname kinds are used to indicate the paternal and maternal family names or generational names indicating father, father or grandfather.  Another new component indicates a generation ("II", "XVI") or parental relation ("Jr.", "Sr.").</t>
        <t>Currently, implementations typically place secondary surnames in the family name components, component and generational markers in the honorific suffixes component.  For backwards compatibility, implementations <bcp14>SHOULD</bcp14> add such values to both the newly defined components and their backwards-compatible counterpart.  Reading N property values, implementations <bcp14>SHOULD</bcp14> ignore any value in the backward-compatible backwards-compatible component if an equal value is set in the according new component. component accordingly.  For example, a "Jr." that occurs in both honorific suffixes and generation should only be handled as a generational marker.</t>

          <dt>Description:</dt>
          <dd>
            Several vCard address book implementations currently use an experimental X-SOCIALPROFILE property to store social media profiles for contacts.  This specification provides an IANA-registered property for the same purpose.  In addition to the typical use of this property with URI values, it also allows setting usernames for social media services as free-text TEXT values, in which case the service name <bcp14>MUST</bcp14> be provided as a parameter.  Names <bcp14>MUST</bcp14> be considered equal if they match case-insensitively.

              This parameter uniquely identifies a property among all of its siblings with the same name within a vCard.  A valid PROP-ID value must be of 1 and a maximum of 255 octets in size, and it MUST <bcp14>MUST</bcp14> only contain the ASCII alphanumeric characters (<tt>A-Za-z0-9</tt>), ("A-Za-z0-9"), hyphen (<tt>-</tt>), (-), and underscore (<tt>_</tt>). ("_").  The identifier identifier's only has the purpose is to uniquely identify siblings, siblings; its value has no other meaning.  If an application makes use of PROP-ID PROP-ID, it <bcp14>SHOULD</bcp14> assign a unique identifier to each sibling property of the same name within their embedding component.  The same identifier <bcp14>MAY</bcp14> be used for properties of a different name, and it <bcp14>MAY</bcp14> also be assigned to a same-named property that is not a sibling.
            </t>
            <t>
              Resolving duplicate identifier conflicts is specific to the application.  Similarly, handling properties where some but not all siblings have a PROP-ID is assigned, assigned is application-specific.
