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).

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:      <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.

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]

     *  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].

  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.

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:    </delete>
  C:    <clTRID>ABC-12345</clTRID>
  C:  </command>
  C:</epp>

  When a <delete> command has been processed successfully, a server
  MUST respond with an EPP response with no <resData> element.

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.

  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

  S:<?xml version="1.0" encoding="UTF-8" standalone="no"?>
  S:<epp xmlns="urn:ietf:params:xml:ns:epp-1.0">
  S:  <response>

  S:</epp>

  An EPP error response MUST be returned if an <update> command cannot
  be processed for any reason.

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:<?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="1001">
  S:      <msg lang="en">Command completed successfully;
  S:        action pending</msg>

  S:        xmlns:org="urn:ietf:params:xml:ns:epp:org-1.0">
  S:        <org:id>res1523</org:id>

  S:    </trID>
  S:  </response>
  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.

  Example "review completed" service message:

  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="1301">

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).

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, [email protected]

     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, [email protected]

     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, [email protected]

     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, [email protected]

     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, [email protected]

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.
