vCard Format Extensions: Internet Corporation for Assigned Names and
Numbers (ICANN) Extensions for the Registration Data Access Protocol
(RDAP)
draft-hollenbeck-vcarddav-icann-rdap-extensions-00
Abstract
This document defines extensions to the vCard data format for
representing and exchanging contact information used to implement the
Internet Corporation for Assigned Names and Numbers (ICANN)
operational profile for the Registration Data Access Protocol (RDAP).
The property and parameter defined here are used to add values to
RDAP responses that are consistent with ICANN policies.

1. Introduction
The Temporary Specification for gTLD Registration Data [1] was
published by the Internet Corporation for Assigned Named and Numbers
(ICANN) in 2018. The Temporary Specification includes requirements
that cannot currently be met by the Registration Data Access Protocol
(RDAP, [RFC7483]) without extending the underlying vCard [RFC6350]
specification used to represent RDAP entity objects. This document
includes specifications for an additional vCard property and an
additional vCard parameter to meet the requirements of the Temporary
Specification.
1.1. Terminology Used in This Document
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
"OPTIONAL" in this document are to be interpreted as described in BCP
14 [RFC2119] [RFC8174] when, and only when, they appear in all
capitals, as shown here.
Syntax specifications shown here use the augmented Backus-Naur Form
(ABNF) as described in [RFC5234], and are specified as in the base
vCard specification [RFC6350].

2. vCard Extensions: Properties
This document describes one new vCard extension property.
2.1. Property: CONTACT-URI
Namespace:
Property name: CONTACT-URI
Purpose: RDAP entity information can be redacted under certain
circumstances (e.g., privacy). The Temporary Specification requires
that RDAP entity objects representing "Registrant", "Admin", and
"Tech" contacts contain an email address or a location for a web form
to facilitate email communication with the relevant contact in a way
that does not identify the associated individual. The CONTACT-URI
property can be used to include URIs representing an email address or
a location for a web form.
Value type: A single URI value.
Cardinality: *
Property parameters: PREF
Description: At least one "mailto", "http", or "https" URI value MUST
be provided. Additional CONTACT-URI properties MAY be provided to
describe other contact methods. If multiple CONTACT-URI properties
are used, the vCard PREF parameter MUST be used to describe the most
preferred property as described in Section 5.3 of RFC 6350 [RFC6350].
Format definition:
CONTACT-URI-param = "VALUE=uri" / pref-param
CONTACT-URI-value = uri
Examples:
CONTACT-URI:https://contact.example.com
CONTACT-URI;PREF=1:mailto:contact@example.com
3. vCard Extensions: Parameters
This document describes one new vCard extension parameter.

Internet-Draft ICANN RDAP vCard Extensions November 2018
3.1. Parameter: CC
Namespace:
Parameter name: CC
Purpose: ICANN requires the use of ISO 3166 [ISO.3166.1988] two-
letter codes, not "country names", in RDAP entity responses. This
parameter is used to extend the ADR property described in
Section 6.3.1 of RFC 6350 [RFC6350].
Description: This parameter contains the ISO 3166 [ISO.3166.1988]
2-character country code associated with the "country name" ADR
component described in Section 6.3.1 of RFC 6350 [RFC6350].
Format definition:
CC-param = "CC=" 2ALPHA
Examples:
ADR;TYPE=work;CC=US:;;12061 Bluemont Way;Reston;VA;20190;USA
ADR;TYPE=home;CC=US:;;12345 Elm St;Reston;VA;20190;USA
4. IANA Considerations
IANA is requested to add the following entry to the vCard Properties
registry defined in Section 10.3.1 of RFC 6350 [RFC6350].
Namespace:
Property: CONTACT-URI
Reference: RFCXXXX (this RFC), Section 2.1
IANA is requested to add the following entry to the vCard Parameters
registry defined in Section 10.3.2 of RFC 6350 [RFC6350].
Namespace:
Property: CC
Reference: RFCXXXX (this RFC), Section 3.1

5. Security Considerations
The CONTACT-URI value is purposefully intended to be a publicly
visible contact reference, and as such, it cannot require privacy
protection. This document presents no other security considerations
beyond those described in Section 9 of the base vCard specification
[RFC6350].
6. Acknowledgements
