RFC 8543 EPP Organization Mapping March 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 have not been formally defined as
having an object in Extensible Provisioning Protocol (EPP). This
document provides a way to specify them as "organization" entities.
This document describes an organization object mapping for version
1.0 of the EPP [RFC5730]. This mapping 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 "org" is used for the namespace
"urn:ietf:params:xml:ns:epp:org-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
An EPP organization object has attributes and associated values that
can be viewed and modified by the sponsoring client or the server.
This section describes each attribute type in detail. The formal
syntax for the attribute values described here can be found in the
"Formal Syntax" section of this document and in the appropriate
normative references.
Zhou, et al. Standards Track [Page 3]
RFC 8543 EPP Organization Mapping March 2019
3.1. Organization Identifier
All EPP organizations are identified by a server-unique identifier.
Organization identifiers are character strings with a specified
minimum length, a specified maximum length, and a specified format.
Organization identifiers use the "clIDType" client identifier syntax
described in [RFC5730]. The corresponding element is <org:id>.
3.2. Organization Roles
The organization roles are used to represent the relationship an
organization could have. The corresponding element is <org:role>.
An organization object MUST always have at least one associated role.
Roles can be set only by the client that sponsors an organization
object. A client can change the role of an organization object using
the EPP <update> command (see Section 4.2.5).
3.2.1. Role Type
An organization role MUST have a type field, which may have any of
the values listed in Section 7.3. The corresponding element is
<org:type>. An organization could have multiple roles with different
role types.
3.2.2. Role Status
A role of an organization object MAY have its own statuses. The
corresponding element is <org:status>. The possible values for the
role status are defined in Section 3.5.
3.2.3. Role Identifier
A role MAY have a third-party-assigned identifier such as the IANA ID
for registrars. The corresponding element is <org:roleID>.
Example of organization role identifier:
<org:role>
<org:type>registrar</org:type>
<org:status>ok</org:status>
<org:status>linked</org:status>
<org:roleID>1362</org:roleID>
</org:role>
Zhou, et al. Standards Track [Page 4]
RFC 8543 EPP Organization Mapping March 2019
3.3. Contact and Client Identifiers
All EPP contacts are identified by server-unique identifiers.
Contact identifiers are character strings with a specified minimum
length, a specified maximum length, and a specified format. Contact
identifiers use the "clIDType" client identifier syntax described in
[RFC5730].
3.4. Organization Status Values
An organization object MUST always have at least one associated
status value. Status values can be set only by the client that
sponsors an organization object and by the server on which the object
resides. A client can change the status of an organization object
using the EPP <update> command. Each status value MAY be accompanied
by a string of human-readable text that describes the rationale for
the status applied to the object.
A client MUST NOT alter server status values set by the server. A
server MAY alter or override status values set by a client, subject
to local server policies. The status of an object MAY change as a
result of either a client-initiated transform command or an action
performed by a server operator.
Status values that can be added or removed by a client are prefixed
with "client". Corresponding server status values that can be added
or removed by a server are prefixed with "server". The "hold" and
"terminated" status values are server managed when the organization
has no parent identifier (Section 3.6) and otherwise MAY be client
managed based on server policy. Other status values that do not
begin with either "client" or "server" are server managed.
Status Value Descriptions:
o ok: This is the normal status value for an object that has no
operations pending or active prohibitions. This value is set and
removed by the server as other status values are added or removed.
o hold: Organization transform commands and new links MUST be
rejected.
o terminated: The organization that has been terminated MUST NOT be
linked. Organization transform commands and new links MUST be
rejected.
Zhou, et al. Standards Track [Page 5]
RFC 8543 EPP Organization Mapping March 2019
o linked: The organization object has at least one active
association with another object. The "linked" status is not
explicitly set by the client. Servers should provide services to
determine existing object associations.
o clientLinkProhibited, serverLinkProhibited: Requests to add new
links to the organization MUST be rejected.
o clientUpdateProhibited, serverUpdateProhibited: Requests to update
the object (other than to remove this status) MUST be rejected.
o clientDeleteProhibited, serverDeleteProhibited: Requests to delete
the object MUST be rejected.
o pendingCreate, pendingUpdate, pendingDelete: A transform command
has been processed for the object, but the action has not been
completed by the server. Server operators can delay action
completion for a variety of reasons, such as to allow for human
review or third-party action. A transform command that is
processed, but whose requested action is pending, is noted with
response code 1001.
"pendingCreate", "ok", "hold", and "terminated" are mutually
exclusive statuses. An organization MUST have exactly one of these
statuses set.
"ok" status MAY only be combined with "linked" status.
A client or server MAY combine "linked" with either
"clientLinkProhibited" or "serverLinkProhibited" if new links must be
prohibited.
"pendingDelete" status MUST NOT be combined with either
"clientDeleteProhibited" or "serverDeleteProhibited" status.
The "pendingCreate", "pendingDelete", and "pendingUpdate" status
values MUST NOT be combined with each other.
If "clientUpdateProhibited" or "serverUpdateProhibited" is set, the
client will not be able to update the object. For
"clientUpdateProhibited", the client will first need to remove
"clientUpdateProhibited" prior to attempting to update the object.
The server can modify the object at any time.
Zhou, et al. Standards Track [Page 6]
RFC 8543 EPP Organization Mapping March 2019
3.5. Role Status Values
A role SHOULD have at least one associated status value. Valid
values include "ok", "linked", "clientLinkProhibited", and
"serverLinkProhibited".
Status Value Descriptions:
o ok: This is the normal status value for a role that has no
operations pending or active prohibitions. This value is set and
removed by the server as other status values are added or removed.
o linked: The role of an organization object has at least one active
association with another object. The "linked" status is not
explicitly set by the client. Servers SHOULD provide services to
determine existing object associations.
o clientLinkProhibited, serverLinkProhibited: Requests to add new
links to the role MUST be rejected.
3.6. Parent Identifier
Organizations can have more than one layer. The parent identifier,
as defined with the <org:parentId> element, represents the parent
organization identifier in a child organization.
The case of reseller organizations provides an example. The parent
identifier is not defined for the top-level reseller, namely the
registrar of the registry. An N-tier reseller has a parent reseller
and at least one child reseller. A reseller customer has a parent
reseller and no child resellers.
Loops MUST be prohibited. For example: if organization A has
organization B as its parent identifier, organization B cannot have
organization A as its parent identifier. The same is true for larger
loops involving three or more organizations.
3.7. URL
The URL represents the organization web home page, as defined with
the <org:url> element.
Zhou, et al. Standards Track [Page 7]
RFC 8543 EPP Organization Mapping March 2019
3.8. Dates and Times
Date and time attribute values MUST be represented in Coordinated
Universal Time (UTC) using the Gregorian calendar. The extended
date-time form using uppercase "T" and "Z" characters defined in
[W3C.REC-xmlschema-2-20041028] MUST be used to represent date-time
values, as XML Schema does not support truncated date-time forms or
lowercase "T" and "Z" characters.
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 use in provisioning and
managing organization information via EPP.
4.1. EPP Query Commands
EPP provides two commands to retrieve organization information:
<check> to determine if an organization object can be provisioned
within a repository and <info> to retrieve detailed information
associated with an organization object. This document does not
define a mapping for the EPP <transfer> command to retrieve
organization-object transfer status information.
4.1.1. EPP <check> Command
The EPP <check> command is used to determine if an object can be
provisioned within a repository. It provides a hint that allows a
client to anticipate the success or failure of provisioning an object
using the <create> command, as object-provisioning requirements are
ultimately a matter of server policy.
In addition to the standard EPP command elements, the <check> command
MUST contain an <org:check> element. This element or its ancestor
element MUST identify the organization namespace
"urn:ietf:params:xml:ns:epp:org-1.0". The <org:check> element
contains the following child elements:
o One or more <org:id> elements that contain the server-unique
identifier of the organization objects to be queried.
Zhou, et al. Standards Track [Page 8]
RFC 8543 EPP Organization Mapping March 2019
Example <check> command:
C:<?xml version="1.0" encoding="UTF-8" standalone="no"?>
C:<epp xmlns="urn:ietf:params:xml:ns:epp-1.0">
C: <command>
C: <check>
C: <org:check
C: xmlns:org="urn:ietf:params:xml:ns:epp:org-1.0">
C: <org:id>res1523</org:id>
C: <org:id>re1523</org:id>
C: <org:id>1523res</org:id>
C: </org:check>
C: </check>
C: <clTRID>ABC-12345</clTRID>
C: </command>
C:</epp>
When a <check> command has been processed successfully, the EPP
<resData> element MUST contain a child <org:chkData> element. This
element or its ancestor element MUST identify the organization
namespace "urn:ietf:params:xml:ns:epp:org-1.0". The <org:chkData>
element contains one or more <org:cd> elements that contain the
following child elements:
o An <org:id> element that identifies the queried object. This
element MUST contain an "avail" attribute whose value indicates
object availability (can it be provisioned or not) at the moment
the <check> command was completed. A value of "1" or "true" means
that the object can be provisioned. A value of "0" or "false"
means that the object cannot be provisioned.
o An OPTIONAL <org:reason> element that may be provided when an
object cannot be provisioned. If present, this element contains
server-specific text to help explain why the object cannot be
provisioned. This text MUST be represented in the response
language previously negotiated with the client; an OPTIONAL "lang"
attribute as defined in [RFC5646] may be present to identify the
language if the negotiated value is something other than the
default value of "en"(English).
Zhou, et al. Standards Track [Page 9]
RFC 8543 EPP Organization Mapping March 2019
Example <check> response:
S:<?xml version="1.0" encoding="UTF-8" standalone="no"?>
S:<epp xmlns="urn:ietf:params:xml:ns:epp-1.0">
S: <response>
S: <result code="1000">
S: <msg lang="en">Command completed successfully</msg>
S: </result>
S: <resData>
S: <org:chkData
S: xmlns:org="urn:ietf:params:xml:ns:epp:org-1.0">
S: <org:cd>
S: <org:id avail="1">res1523</org:id>
S: </org:cd>
S: <org:cd>
S: <org:id avail="0">re1523</org:id>
S: <org:reason lang="en">In use</org:reason>
S: </org:cd>
S: <org:cd>
S: <org:id avail="1">1523res</org:id>
S: </org:cd>
S: </org:chkData>
S: </resData>
S: <trID>
S: <clTRID>ABC-12345</clTRID>
S: <svTRID>54322-XYZ</svTRID>
S: </trID>
S: </response>
S:</epp>
An EPP error response MUST be returned if a <check> command cannot be
processed for any reason.
4.1.2. EPP <info> Command
The EPP <info> command is used to retrieve information associated
with an organization object. In addition to the standard EPP command
elements, the <info> command MUST contain an <org:info> element.
This element or its ancestor element MUST identify the organization
namespace "urn:ietf:params:xml:ns:epp:org-1.0". The <org:info>
element contains the following child element:
o An <org:id> element that contains the server-unique identifier of
the organization object to be queried.
Zhou, et al. Standards Track [Page 10]
RFC 8543 EPP Organization Mapping March 2019
Example <info> command:
C:<?xml version="1.0" encoding="UTF-8" standalone="no"?>
C:<epp xmlns="urn:ietf:params:xml:ns:epp-1.0">
C: <command>
C: <info>
C: <org:info
C: xmlns:org="urn:ietf:params:xml:ns:epp:org-1.0">
C: <org:id>res1523</org:id>
C: </org:info>
C: </info>
C: <clTRID>ABC-12345</clTRID>
C: </command>
C:</epp>
When an <info> command has been processed successfully, the EPP
<resData> element MUST contain a child <org:infData> element. This
element or its ancestor element MUST identify the organization
namespace "urn:ietf:params:xml:ns:epp:org-1.0". The <org:infData>
element contains the following child elements:
o An <org:id> element that contains the server-unique identifier of
the organization object, as defined in Section 3.1.
o An <org:roid> element that contains the Repository Object
Identifier assigned to the organization object when the object was
created.
o One or more <org:role> elements that contain the role type, role
statuses, and optional role ID of the organization.
* An <org:type> element that contains the type of the
organization, as defined in Section 3.2.
* One or more <org:status> elements that contain the role
statuses. The values of the role status are defined in
Section 3.5.
* An OPTIONAL <org:roleID> element that contains a third-party-
assigned identifier, such as IANA ID for registrars, as defined
in Section 3.2.3.
o One or more <org:status> elements that contain the operational
status of the organization, as defined in Section 3.4.
o An OPTIONAL <org:parentId> element that contains the identifier of
the parent object, as defined in Section 3.6.
Zhou, et al. Standards Track [Page 11]
RFC 8543 EPP Organization Mapping March 2019
o Zero to two <org:postalInfo> elements that contain postal-address
information. Two elements are provided so that address
information can be provided in both internationalized and
localized forms; a "type" attribute is used to identify the two
forms. If an internationalized form (type="int") is provided,
element content MUST be represented in a subset of Unicode
[UNICODE] in the range U+0020 - U+007E. If a localized form
(type="loc") is provided, element content MAY be represented in
unrestricted UTF-8. The <org:postalInfo> element contains the
following child elements:
* An <org:name> element that contains the name of the
organization.
* An OPTIONAL <org:addr> element that contains address
information associated with the organization. An <org:addr>
element contains the following child elements:
+ One, two, or three <org:street> elements that contain the
organization's street address.
+ An <org:city> element that contains the organization's city.
+ An OPTIONAL <org:sp> element that contains the
organization's state or province.
+ An OPTIONAL <org:pc> element that contains the
organization's postal code.
+ An <org:cc> element that contains the alpha-2 organization's
country code. The detailed format of this element is
described in Section 2.4.3 of [RFC5733].
o An OPTIONAL <org:voice> element that contains the organization's
voice telephone number. The detailed format of this element is
described in Section 2.5 of [RFC5733].
o An OPTIONAL <org:fax> element that contains the organization's
facsimile telephone number. The detailed format of this element
is described in Section 2.5 of [RFC5733].
o An OPTIONAL <org:email> element that contains the organization's
email address. The detailed format of this element is described
in [RFC5322].
o An OPTIONAL <org:url> element that contains the URL to the website
of the organization. The detailed format of this element is
described in [RFC3986].
Zhou, et al. Standards Track [Page 12]
RFC 8543 EPP Organization Mapping March 2019
o Zero or more <org:contact> elements that contain identifiers for
the contact objects to be associated with the organization object.
Contact object identifiers MUST be known to the server before the
contact object can be associated with the organization object.
The required "type" is used to represent contact types. The type
values include "admin", "tech", "billing", "abuse", and "custom".
The OPTIONAL "typeName" attribute is used to define the name of a
"custom" type.
o An OPTIONAL <org:clID> element that contains the organization
identifier of the sponsoring client. There is no <org:clID>
element if the organization is managed by the registry.
o An <org:crID> element that contains the identifier of the client
that created the organization object.
o An <org:crDate> element that contains the date and time of
organization object creation.
o An <org:upID> element that contains the identifier of the client
that last updated the organization object. This element MUST NOT
be present if the organization has never been modified.
o An <org:upDate> element that contains the date and time of the
most recent organization object modification. This element MUST
NOT be present if the organization object has never been modified.

An EPP error response MUST be returned if an <info> command cannot be
processed for any reason.
4.1.3. EPP <transfer> Query Command
The transfer semantics do not apply to organization objects. No EPP
<transfer> query command is defined in this document.
Zhou, et al. Standards Track [Page 15]
RFC 8543 EPP Organization Mapping March 2019
4.2. EPP Transform Commands
This document provides three commands to transform organization
object information: <create> to create an instance of an organization
object, <delete> to delete an instance of an organization object, and
<update> to change information associated with an organization
object. This document does not define a mapping for the EPP
<transfer> and <renew> command.
Transform commands are typically processed and completed in real
time. Server operators MAY receive and process transform commands
but defer completing the requested action if human or third-party
review is required before the requested action can be completed. In
such situations, the server MUST return a 1001 response code to the
client to note that the command has been received and processed but
that the requested action is pending. The server MUST also manage
the status of the object that is the subject of the command to
reflect the initiation and completion of the requested action. Once
the action has been completed, the client MUST be notified using a
service message that the action has been completed and the status of
the object has changed. Other notification methods MAY be used in
addition to the required service message.
4.2.1. EPP <create> Command
The EPP <create> command provides a transform operation that allows a
client to create an organization object. In addition to the standard
EPP command elements, the <create> command MUST contain an
<org:create> element. This element or its ancestor element MUST
identify the organization namespace "urn:ietf:params:xml:ns:epp:org-
1.0". The <org:create> element contains the following child
elements:
o An <org:id> element that contains the desired server-unique
identifier for the organization to be created, as defined in
Section 3.1.
o One or more <org:role> elements that contain the role type, role
statuses, and optional role ID of the organization.
* An <org:type> element that contains the type of the
organization, as defined in Section 3.2.
* Zero or more <org:status> elements that contain the role
statuses. The possible values of the role statuses are defined
in Section 3.5.
Zhou, et al. Standards Track [Page 16]
RFC 8543 EPP Organization Mapping March 2019
* An OPTIONAL <org:roleID> element that contains a third-party-
assigned identifier, such as IANA ID for registrars, as defined
in Section 3.2.3.
o Zero or more <org:status> elements that contain the operational
status of the organization, as defined in Section 3.4.
o An OPTIONAL <org:parentId> element that contains the identifier of
the parent object, as defined in Section 3.6.
o Zero to two <org:postalInfo> elements that contain postal-address
information. Two elements are provided so that address
information can be provided in both internationalized and
localized forms; a "type" attribute is used to identify the two
forms. If an internationalized form (type="int") is provided,
element content MUST be represented in a subset of Unicode
[UNICODE] in the range U+0020 - U+007E. If a localized form
(type="loc") is provided, element content MAY be represented in
unrestricted UTF-8. The <org:postalInfo> element contains the
following child elements:
* An <org:name> element that contains the name of the
organization.
* An OPTIONAL <org:addr> element that contains address
information associated with the organization. An <org:addr>
element contains the following child elements:
+ One, two, or three <org:street> elements that contain the
organization's street address.
+ An <org:city> element that contains the organization's city.
+ An OPTIONAL <org:sp> element that contains the
organization's state or province.
+ An OPTIONAL <org:pc> element that contains the
organization's postal code.
+ An <org:cc> element that contains the alpha-2 organization's
country code. The detailed format of this element is
described in Section 2.4.3 of [RFC5733].
o An OPTIONAL <org:voice> element that contains the organization's
voice telephone number. The detailed format of this element is
described in Section 2.5 of [RFC5733].
Zhou, et al. Standards Track [Page 17]
RFC 8543 EPP Organization Mapping March 2019
o An OPTIONAL <org:fax> element that contains the organization's
facsimile telephone number. The detailed format of this element
is described in Section 2.5 of [RFC5733].
o An OPTIONAL <org:email> element that contains the organization's
email address. The detailed format of this element is described
of [RFC5322].
o An OPTIONAL <org:url> element that contains the URL to the website
of the organization. The detailed format of this element is
described in [RFC3986].
o Zero or more <org:contact> elements that contain identifiers for
the contact objects associated with the organization object.

When a <create> command has been processed successfully, the EPP
<resData> element MUST contain a child <org:creData> element. This
element or its ancestor element MUST identify the organization
namespace "urn:ietf:params:xml:ns:epp:org-1.0". The <org:creData>
element contains the following child elements:
o An <org:id> element that contains the server-unique identifier for
the created organization, as defined in Section 3.1.
o An <org:crDate> element that contains the date and time of
organization-object creation.

4.2.2. EPP <delete> Command
The EPP <delete> command provides a transform operation that allows a
client to delete an organization object. In addition to the standard
EPP command elements, the <delete> command MUST contain an
<org:delete> element. This element or its ancestor element MUST
identify the organization namespace "urn:ietf:params:xml:ns:epp:org-
1.0". The <org:delete> element MUST contain the following child
element:
o An <org:id> element that contains the server-unique identifier of
the organization object to be deleted, as defined in Section 3.1.
An organization object MUST NOT be deleted if it is associated with
other known objects. An associated organization MUST NOT be deleted
until associations with other known objects have been broken. A
server MUST notify clients that object relationships exist by sending
a 2305 error response code when a <delete> command is attempted and
fails due to existing object relationships.
Example <delete> command:
C:<?xml version="1.0" encoding="UTF-8" standalone="no"?>
C:<epp xmlns="urn:ietf:params:xml:ns:epp-1.0">
C: <command>
C: <delete>

4.2.3. EPP <renew> Command
Renewal semantics do not apply to organization objects, so there is
no mapping defined for the EPP <renew> command.
4.2.4. EPP <transfer> Command
Transfer semantics do not apply to organization objects, so there is
no mapping defined for the EPP <transfer> command.
4.2.5. EPP <update> Command
The EPP <update> command provides a transform operation that allows a
client to modify the attributes of an organization object. In
addition to the standard EPP command elements, the <update> command
MUST contain an <org:update> element. This element or its ancestor
element MUST identify the organization namespace
"urn:ietf:params:xml:ns:epp:org-1.0". The <org:update> element
contains the following child elements:
o An <org:id> element that contains the server-unique identifier of
the organization object to be updated, as defined in Section 3.1.
o An OPTIONAL <org:add> element that contains attribute values to be
added to the object.
o An OPTIONAL <org:rem> element that contains attribute values to be
removed from the object.
Zhou, et al. Standards Track [Page 21]
RFC 8543 EPP Organization Mapping March 2019
o An OPTIONAL <org:chg> element that contains attribute values to be
changed.
At least one <org:add>, <org:rem>, or <org:chg> element MUST be
provided if the command is not being extended. All of these elements
MAY be omitted if an <update> extension is present. The OPTIONAL
<org:add> and <org:rem> elements contain the following child
elements:
o Zero or more <org:contact> elements that contain the identifiers
for contact objects to be associated with or removed from the
organization object. Contact object identifiers MUST be known to
the server before the contact object can be associated with the
organization object.
o Zero or more <org:role> elements that contain the role type, role
statuses, and optional role ID of the organization.
* An <org:type> element that contains the role type of the
organization, as defined in Section 3.2. The role type
uniquely identifies the role to update.
* Zero or more <org:status> elements that contain the role
statuses. The values of the role status are defined in
Section 3.5.
* An OPTIONAL <org:roleID> element that contains a third-party-
assigned identifier, such as IANA ID for registrars, as defined
in Section 3.2.3.
o Zero or more <org:status> elements that contain the operational
status of the organization.
An OPTIONAL <org:chg> element contains the following child elements,
where at least one child element MUST be present:
o An OPTIONAL <org:parentId> element that contains the identifier of
the parent object.
o Zero to two <org:postalInfo> elements that contain postal-address
information. Two elements are provided so that address
information can be provided in both internationalized and
localized forms; a "type" attribute is used to identify the two
forms. If an internationalized form (type="int") is provided,
element content MUST be represented in a subset of Unicode
[UNICODE] in the range U+0020 - U+007E. If a localized form
(type="loc") is provided, element content MAY be represented in
unrestricted UTF-8. The change of the postal info is defined as a
Zhou, et al. Standards Track [Page 22]
RFC 8543 EPP Organization Mapping March 2019
replacement of that postal info element with the contents of the
sub-elements included in the <update> command. An empty
<org:postalInfo> element is supported to allow a type of postal
info to be removed. The <org:postalInfo> element contains the
following child elements:
* An <org:name> element that contains the name of the
organization.
* An OPTIONAL <org:addr> element that contains address
information associated with the organization. An <org:addr>
element contains the following child elements:
+ One, two, or three <org:street> elements that contain the
organization's street address.

4.3. Offline Review of Requested Actions
Commands are processed by a server in the order they are received
from a client. Though an immediate response confirming receipt and
processing of the command is produced by the server, a server
operator MAY perform an offline review of requested transform
commands before completing the requested action. In such situations,
the response from the server MUST clearly note that the transform
command has been received and processed, but the requested action is
pending. The status in the response of the corresponding object MUST
clearly reflect processing of the pending action. The server MUST
notify the client when offline processing of the action has been
completed.
Examples describing a <create> command that requires offline review
are included here. Note the result code and message returned in
response to the <create> command.

S:</epp>
The status of the organization object after returning this response
MUST include "pendingCreate". The server operator reviews the
request offline and informs the client of the outcome of the review
by queuing a service message for retrieval via the <poll> command; it
MAY additionally use an out-of-band mechanism to inform the client of
the outcome.
The service message MUST contain text that describes the notification
in the child <msg> element of the response <msgQ> element. In
addition, the EPP <resData> element MUST contain a child
<org:panData> element. This element or its ancestor element MUST
identify the organization namespace "urn:ietf:params:xml:ns:epp:org-
1.0". The <org:panData> element contains the following child
elements:
o An <org:id> element that contains the server-unique identifier of
the organization object. The <org:id> element contains a REQUIRED
"paResult" attribute. A positive boolean value indicates that the
request has been approved and completed. A negative boolean value
indicates that the request has been denied and the requested
action has not been taken.
o An <org:paTRID> element that contains the client transaction
identifier and server transaction identifier returned with the
original response to process the command. The client transaction
identifier is OPTIONAL and will only be returned if the client
provided an identifier with the original <create> command.
o An <org:paDate> element that contains the date and time describing
when review of the requested action was completed.

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.

RFC 8543 EPP Organization Mapping March 2019
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 organization 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 namespace:
URI: urn:ietf:params:xml:ns:epp:org-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:org-1.0
Registrant Contact: IESG
XML: See the "Formal Syntax" section of RFC 8543 (this document).
Zhou, et al. Standards Track [Page 36]
RFC 8543 EPP Organization Mapping March 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: Extensible Provisioning Protocol (EPP)
Organization Mapping
Document status: Standards Track
Reference: RFC 8543
Registrant Name and Email Address: IESG, iesg@ietf.org
TLDs: Any
IPR Disclosure: None
Status: Active
Notes: None
7.3. Role Type Values Registry
IANA has created a new category of protocol registry for values of
the organization roles. The name of this registry is "EPP
Organization Role Values". The registration policy for this registry
is "Expert Review" [RFC8126].
7.3.1. Registration Template
Value: The string value being registered.
Description: Brief description of the organization role values.
Registrant Name: For RFC specifications, state "IESG". For other
specifications, give the name of the responsible party.
Registrant Contact Information: An email address, postal address, or
some other information to be used to contact the registrant.
Zhou, et al. Standards Track [Page 37]
RFC 8543 EPP Organization Mapping March 2019
7.3.2. Initial Registry Contents
The following are the initial registry contents:
Value: registrar
Description: The entity object instance represents the authority
responsible for the registration in the registry.
Registrant: IESG, iesg@ietf.org
Value: reseller
Description: The entity object instance represents a third party
through which the registration was conducted (i.e., not the
registry or registrar).
Registrant: IESG, iesg@ietf.org
Value: privacyproxy
Description: The entity object instance represents a third party
who could help to register a domain without exposing the
registrants' private information.
Registrant: IESG, iesg@ietf.org
Value: dns-operator
Description: The entity object instance represents a third-party
DNS operator that maintains the name servers and zone data on
behalf of a registrant.
Registrant: IESG, iesg@ietf.org
8. Security Considerations
The organization object may have personally identifiable information,
such as <org:contact>. This information is not a required element in
this document that can be provided on a voluntary basis. If it is
provided, both client and server MUST ensure that authorization
information is stored and exchanged with high-grade encryption
mechanisms to provide privacy services, which are specified in
[RFC5733]. The security considerations described in [RFC5730] or
those caused by the protocol layers used by EPP will apply to this
specification as well.
