1. Introduction
The Registration Data Access Protocol (RDAP, [RFC7483]) represents
contact information pertaining to the entities associated with
internet identifiers (such as domain names, IP address blocks, and
autonmymous system numbers) using jCard ([RFC7095]). jCard is a JSON
mapping of vCard ([RFC6350]) into JSON ([RFC4627]).
vCard is a generalised specification for entries in an "address
book", and provides a broad and extensible framework for storing
attributes associated with an individual, group or organisation.
However, as RDAP has been deployed by Regional Internet Registries
(RIRs) and domain name registries (DNRs), the complexity of the jCard
has been identified as having a negative effect on the ease of
implementing the RDAP specifications.
The Extensible Provisioning Protocol (EPP) is widely deployed by
domain name registries to facilitate provisioning of domain names and
other objects by registrars. The EPP Contact Mapping, defined in
[RFC5733], provides a lightweight structure to describe contact
information such as name, organization, postal and addresses, and
voice and fax numbers.
This document describes a way to map the structure of contact
information described in RFC5733 into JSON, and also how this
representation can be used in RDAP entity objects instead of jCard.
1.1. Conventions Used in This Document
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in [RFC2119].

2. JSON Mapping of EPP Contact Objects
This mapping is limited to the attributes of contact objects
described in sections 2.3 - 2.6 of RFC 5733. Other attributes, such
as unique IDs, status codes, and event actions, are already
adequately mapped to generic RDAP object attributes.
An EPP contact object may be represented in JSON by constructing a
JSON object with the following properties:
postalInfo this property is an object that contains the postal
address information.
voice this property is a string containing the voice number.
fax this property is a string containing the facsimile number.
email this property is a string containing the email address.
The "voice", "fax" and "email" properties MAY be omitted or NULL, but
if present, MUST be valid as per the validation rules described in
the XML schema in RFC 5733.
2.1. Postal Address Information
Every contact has associated postal-address information which may be
represented in either ASCII (for international use) or UTF-8 (for
domestic use).
The "postalInfo" property is an object with two properties: "int" and
"loc". These properties may contain postal information or may either
be omitted or NULL, but at least one MUST be present and contain
valid postal address information.
The postal address information in the "loc" object may contain any
valid UTF-8 sequence, but the data in the "int" object MUST NOT
contain any characters outside the ASCII range (U+0000 - U+007F).
The "int" and "loc" properties are JSON objects which may contain any
of the following:
name a string containing the contact name.
org a string containing the organization.
addr an object containing the following properties:
Brown Expires August 22, 2019 [Page 3]
Internet-Draft EPP Contact Mapping for RDAP February 2019
street a JSON array containing between one and three strings
contain the street address.
city a string containing the city.
sp a string containing the state or province.
pc a string containing the postal code.
cc the two-character country identifier specified in ISO 3166.
2.2. Example
The following is a JSON representation of the example contact object
shown in Section 3.1.2 of RFC 5733:
{
"postalInfo": {
"int": {
"name": "John Doe",
"org": "Example Inc.",
"addr": {
"street": [
"123 Example Dr.",
"Suite 100"
],
"city": "Dulles",
"sp": "VA",
"pc": "20166-6503",
"cc": "US",
},
},
"loc": NULL
},
"voice": "+1.7035555555x1234",
"fax": "+1.7035555556",
"email": "jdoe@example.com"
}
3. Usage in RDAP
RDAP servers MAY use the contact object representation described in
this document in entity object instead of jCard.
RDAP servers which do so MUST add the
"epp_entity_contact_info_level_0" string to the "rdapConformance"
array at the top-level of the RDAP response. This string as has been
registered with IANA.

Internet-Draft EPP Contact Mapping for RDAP February 2019
In place of the "vCardArray" property, servers may then insert an
"eppContactInfo" property, whose value is a JSON object described in
this document.
3.1. Example
The following is an example of an RDAP entity which uses the EPP
contact mapping instead of jCard:
{
"rdapConformance": [
"rdap_level_0",
"epp_entity_contact_info_level_0"
],
"objectClassName": "entity",
"handle": "SH8013-REP",
"eppContactInfo": {
"postalInfo": {
"int": {
"name": "John Doe",
"org": "Example Inc.",
"addr": {
"street": [
"123 Example Dr.",
"Suite 100"
],
"city": "Dulles",
"sp": "VA",
"pc": "20166-6503",
"cc": "US",
},
},
"loc": NULL
},
"voice": "+1.7035555555x1234",
"fax": "+1.7035555556",
"email": "jdoe@example.com"
},
// rest of entity
}
