RFC 8544 Organization Extension for the EPP April 2019
1. Introduction
There are many entities, such as registrars, resellers, DNS service
operators, and privacy proxies, involved in the domain registration
business. These kinds of entities are supported in the Extensible
Provisioning Protocol (EPP) by the "organization" entities in
[RFC8543]. This document provides a way to associate any EPP object
such as domain names in [RFC5731], hosts in [RFC5732], and contacts
in [RFC5733] to "organization" entities in [RFC8543]. The examples
provided in this document are used for the domain object for
illustration purposes. The host and contact object could be extended
in the same way as the domain object.
Organization object identifiers, defined in [RFC8543], MUST be known
to the server before the organization object can be associated with
the EPP object.
This document is specified using XML 1.0 as described in
[W3C.REC-xml-20081126] and XML Schema notation as described in
[W3C.REC-xmlschema-1-20041028] and [W3C.REC-xmlschema-2-20041028].
2. Conventions 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.
In examples, "C:" represents lines sent by a protocol client, and
"S:" represents lines returned by a protocol server. Indentation and
white space in examples are provided only to illustrate element
relationships and are not a required feature of this specification.
XML is case sensitive. Unless stated otherwise, XML specifications
and examples provided in this document MUST be interpreted in the
character case presented.
The XML namespace prefix "orgext" is used for the namespace
"urn:ietf:params:xml:ns:epp:orgext-1.0", but implementations MUST NOT
depend on it; instead, they should employ a proper namespace-aware
XML parser and serializer to interpret and output the XML documents.
3. Object Attributes
This extension adds additional elements to EPP object mappings such
as the EPP domain name mapping [RFC5731]. Only the new elements are
described here.
Zhou, et al. Standards Track [Page 3]
RFC 8544 Organization Extension for the EPP April 2019
3.1. Organization Identifier
The organization identifier provides the ID of an organization. Its
corresponding element is <orgext:id>, which refers to the <org:id>
element defined in [RFC8543]. All organization objects are
identified by a server-unique identifier. A "role" attribute is used
to represent the relationship that the organization has to the EPP
object. Any given object MUST have at most one associated
organization ID for any given role value.
4. EPP Command Mapping
A detailed description of the EPP syntax and semantics can be found
in the EPP core protocol specification [RFC5730]. The command
mappings described here are specifically for assigning organizations
to EPP objects.
4.1. EPP Query Commands
EPP provides three commands to retrieve EPP object information:
<check> to determine if an object can be provisioned within a
repository, <info> to retrieve detailed information associated with
an object, and <transfer> to retrieve object transfer status
information.
4.1.1. EPP <check> Command
This extension does not add any elements to the EPP <check> command
or <check> response described in the EPP object mapping.
4.1.2. EPP <info> Command
This extension does not add any elements to the EPP <info> command
described in the EPP object mapping. However, additional elements
are defined for the <info> response in the EPP object mapping.
When an <info> command has been processed successfully, the EPP
<resData> element MUST contain child elements as described in the EPP
object extensions. In addition, the EPP <extension> element SHOULD
contain a child <orgext:infData> element. This element is returned
if the object has data that is associated with this extension and
that is based on server policy. This element or its ancestor element
Zhou, et al. Standards Track [Page 4]
RFC 8544 Organization Extension for the EPP April 2019
MUST identify the extension namespace
"urn:ietf:params:xml:ns:epp:orgext-1.0". The <orgext:infData>
element contains the following child elements:
o Zero or more <orgext:id> elements are allowed that contain the
identifier of the organization, as defined in Section 3.1. The
"role" attribute is used to represent the relationship that the
organization has to the object. See Section 7.3 of [RFC8543] for
a list of values.
Example <info> response for an authorized client with multiple
organizations:

RFC 8544 Organization Extension for the EPP April 2019
4.1.3. EPP <transfer> Query Command
This extension does not add any elements to the EPP <transfer> query
command or <transfer> query response described in the EPP object
mapping.
4.2. EPP Transform Commands
EPP provides five commands to transform EPP objects: <create> to
create an instance of an object, <delete> to delete an instance of an
object, <renew> to extend the validity period of an object,
<transfer> to manage the object sponsorship changes, and <update> to
change information associated with an object.
4.2.1. EPP <create> Command
This extension defines additional elements for the EPP <create>
command described in the EPP object extensions. No additional
elements are defined for the EPP <create> response.
The EPP <create> command provides a transform operation that allows a
client to create an object. In addition to the EPP command elements
described in the EPP object extensions, the command MUST contain an
<extension> element, and the <extension> element MUST contain a child
<orgext:create> element. This element is used if the client wants to
associate data defined in this extension to the object. This element
or its ancestor element MUST identify the extension namespace
"urn:ietf:params:xml:ns:epp:orgext-1.0". The <orgext:create> element
contains the following child elements:
o One or more <orgext:id> elements that contain the identifier of
the organization, as defined in Section 3.1. The "role" attribute
is used to represent the relationship that the organization has to
the object. See Section 7.3 of [RFC8543] for a list of values.

C: <clTRID>ABC-12345</clTRID>
C: </command>
C:</epp>
When a <create> command has been processed successfully, the EPP
response is as described in the EPP object extension.
An EPP error response MUST be returned if a <create> command cannot
be processed for any reason.
4.2.2. EPP <delete> Command
This extension does not add any elements to the EPP <delete> command
or <delete> response described in the EPP object mapping.
4.2.3. EPP <renew> Command
This extension does not add any elements to the EPP <renew> command
or <renew> response described in the EPP object mapping.
Zhou, et al. Standards Track [Page 10]
RFC 8544 Organization Extension for the EPP April 2019
4.2.4. EPP <transfer> Command
This extension does not add any elements to the EPP <transfer>
command or <transfer> response described in the EPP object mapping,
but after a successful transfer of an object with an assigned
organization, the handling of the assigned organization is dependent
on the organization roles and server policy.
4.2.5. EPP <update> Command
This extension defines additional elements for the EPP <update>
command described in the EPP domain mapping [RFC5731], host mapping
[RFC5732], and contact mapping [RFC5733]. No additional elements are
defined for the EPP <update> response.
The EPP <update> command provides a transform operation that allows a
client to modify the attributes of an object. In addition to the EPP
<update> command elements, the command MUST contain an <extension>
element, and the <extension> element MUST contain a child
<orgext:update> element. This element is used if the client wants to
update the object with data defined in this extension. This element
or its ancestor element MUST identify the extension namespace
"urn:ietf:params:xml:ns:epp:orgext-1.0". The <orgext:update> element
contains the following child elements:
o An OPTIONAL <orgext:add> element that contains one or more
<orgext:id> elements, as defined in Section 3.1, that add
nonexistent organization roles to the object. The <orgext:id>
element MUST have a non-empty organization identifier value. The
server SHOULD validate that the <orgext:id> element role does not
exist.
o An OPTIONAL <orgext:rem> element that contains one or more
<orgext:id> elements, as defined in Section 3.1, that remove
organization roles from the object. The <orgext:id> element MAY
have an empty organization identifier value. The server SHOULD
validate the existence of the <orgext:id> element role and the
organization identifier if provided.
o An OPTIONAL <orgext:chg> element that contains one or more
<orgext:id> elements, as defined in Section 3.1, that change
organization role identifiers for the object. The existing
organization identifier value will be replaced for the defined
role. The server SHOULD validate the existence of the <orgext:id>
element role.
At least one <orgext:add>, <orgext:rem>, or <orgext:chg> element MUST
be provided.

An EPP error response MUST be returned if an <update> command cannot
be processed for any reason. An attempt to add one organization ID
or multiple organization IDs with a particular role value when at
least one of them already exists does not change the object at all.
A server SHOULD notify clients that object relationships exist by
sending a 2305 error response code. An attempt to remove an
organization ID or multiple organization IDs with a particular role
value when at least one of them does not exist does not change the
object at all. A server SHOULD notify clients that object
relationships do not exist by sending a 2305 error response code. An
attempt to change an organization ID or multiple organization IDs
with a particular role value when at least one of them does not exist
does not change the object at all. A server SHOULD notify clients
that object relationships do not exist by sending a 2305 error
response code. Response format with error value elements is defined
in Section 2.6 of [RFC5730].
5. Formal Syntax
An EPP object mapping is specified in XML Schema notation. The
formal syntax presented here is a complete schema representation of
the object mapping suitable for automated validation of EPP XML
instances. The BEGIN and END tags are not part of the schema; they
are used to note the beginning and ending of the schema for URI
registration purposes.

6. Internationalization Considerations
EPP is represented in XML, which provides native support for encoding
information using the Unicode character set [UNICODE] and its more
compact representations, including UTF-8. Conformant XML processors
recognize both UTF-8 [RFC3629] and UTF-16 [RFC2781]. Though XML
includes provisions to identify and use other character encodings
through use of an "encoding" attribute in an <?xml?> declaration, use
of UTF-8 is RECOMMENDED.
As an extension of the EPP object mapping, the elements and element
content described in this document MUST inherit the
internationalization conventions used to represent higher-layer
domain and core protocol structures present in an XML instance that
includes this extension.
7. IANA Considerations
7.1. XML Namespace
This document uses URNs to describe XML namespaces and XML schemas
conforming to a registry mechanism described in [RFC3688]. IANA has
assigned the following URI.
The organization extension namespace:
URI: urn:ietf:params:xml:ns:epp:orgext-1.0
Registrant Contact: IESG
XML: None. Namespace URIs do not represent an XML specification.
The organization XML schema:
URI: urn:ietf:params:xml:schema:epp:orgext-1.0
Registrant Contact: IESG
XML: See the "Formal Syntax" section of RFC 8544 (this document).

RFC 8544 Organization Extension for the EPP April 2019
7.2. EPP Extension Registry
The EPP extension described in this document has been registered by
IANA in the "Extensions for the Extensible Provisioning Protocol
(EPP)" registry described in [RFC7451]. The details of the
registration are as follows:
Name of Extension: Organization Extension for the Extensible
Provisioning Protocol (EPP)
Document Status: Standards Track
Reference: RFC 8544
Registrant Name and Email Address: IESG, iesg@ietf.org
TLDs: Any
IPR Disclosure: None
Status: Active
Notes: None
8. Security Considerations
The object mapping extension described in this document does not
provide any other security services or introduce any additional
considerations beyond those described by [RFC5730], [RFC5731],
[RFC5732], and [RFC5733] or those caused by the protocol layers used
by EPP.
