Hollenbeck Standards Track [Page 2]RFC 4933 EPP Contact Mapping May 2007
1. Introduction
This document describes a personal and organizational identifier
mapping for version 1.0 of the Extensible Provisioning Protocol
(EPP). This mapping is specified using the Extensible Markup
Language (XML) 1.0 as described in [W3C.REC-xml-20040204] and XML
Schema notation as described in [W3C.REC-xmlschema-1-20041028] and
[W3C.REC-xmlschema-2-20041028]. This document obsoletes RFC 3733
[RFC3733].
[RFC4930] provides a complete description of EPP command and response
structures. A thorough understanding of the base protocol
specification is necessary to understand the mapping described in
this document.
XML is case sensitive. Unless stated otherwise, XML specifications
and examples provided in this document MUST be interpreted in the
character case presented to develop a conforming implementation.
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].
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 protocol.
2. Object Attributes
An EPP contact 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.
2.1. Contact and Client Identifiers
All EPP contacts are identified by a server-unique identifier.
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
[RFC4930].
Hollenbeck Standards Track [Page 3]
RFC 4933 EPP Contact Mapping May 2007
2.2. Status Values
A contact object MUST always have at least one associated status
value. Status values can be set only by the client that sponsors a
contact object and by the server on which the object resides. A
client can change the status of a contact 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 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 status values that can be added or
removed by a server are prefixed with "server". Status values that
do not begin with either "client" or "server" are server-managed.
Status Value Descriptions:
- clientDeleteProhibited, serverDeleteProhibited
Requests to delete the object MUST be rejected.
- clientTransferProhibited, serverTransferProhibited
Requests to transfer the object MUST be rejected.
- clientUpdateProhibited, serverUpdateProhibited
Requests to update the object (other than to remove this status)
MUST be rejected.
- linked
The contact object has at least one active association with
another object, such as a domain object. Servers SHOULD provide
services to determine existing object associations.
- ok
This is the normal status value for an object that has no pending
operations or prohibitions. This value is set and removed by the
server as other status values are added or removed.
Hollenbeck Standards Track [Page 4]RFC 4933 EPP Contact Mapping May 2007
- pendingCreate, pendingDelete, pendingRenew, pendingTransfer,
pendingUpdate
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.
When the requested action has been completed, the pendingCreate,
pendingDelete, pendingTransfer, or pendingUpdate status value MUST be
removed. All clients involved in the transaction MUST be notified
using a service message that the action has been completed and that
the status of the object has changed.
"ok" status MAY only be combined with "linked" status.
"linked" status MAY be combined with any status.
"pendingDelete" status MUST NOT be combined with either
"clientDeleteProhibited" or "serverDeleteProhibited" status.
"pendingTransfer" status MUST NOT be combined with either
"clientTransferProhibited" or "serverTransferProhibited" status.
"pendingUpdate" status MUST NOT be combined with either
"clientUpdateProhibited" or "serverUpdateProhibited" status.
The pendingCreate, pendingDelete, pendingTransfer, and pendingUpdate
status values MUST NOT be combined with each other.
Other status combinations not expressly prohibited MAY be used.
2.3. Individual and Organizational Names
Individual and organizational names associated with a contact are
represented using character strings. These strings have a specified
minimum length and a specified maximum length. Individual and
organizational names MAY be provided in both UTF-8 [RFC3629] and a
subset of UTF-8 that can be represented in 7-bit ASCII depending on
local needs.
2.4. Address
Every contact has associated postal address information. A postal
address contains OPTIONAL street information, city information,
OPTIONAL state/province information, an OPTIONAL postal code, and a
country identifier. Address information MAY be provided in both
Hollenbeck Standards Track [Page 5]RFC 4933 EPP Contact Mapping May 2007
UTF-8 and a subset of UTF-8 that can be represented in 7-bit ASCII
depending on local needs.
2.4.1. Street, City, and State or Province
Contact street, city, and state or province information is
represented using character strings. These strings have a specified
minimum length and a specified maximum length.
2.4.2. Postal Code
Contact postal codes are represented using character strings. These
strings have a specified minimum length and a specified maximum
length.
2.4.3. Country
Contact country identifiers are represented using two-character
identifiers specified in [ISO.3166.1997].
2.5. Telephone Numbers
Contact telephone number structure is derived from structures defined
in [ITU.E164.2005]. Telephone numbers described in this mapping are
character strings that MUST begin with a plus sign ("+", ASCII value
0x002B), followed by a country code defined in [ITU.E164.2005],
followed by a dot (".", ASCII value 0x002E), followed by a sequence
of digits representing the telephone number. An optional "x"
attribute is provided to note telephone extension information.
2.6. Email Addresses
Email address syntax is defined in [RFC0822]. This mapping does not
prescribe minimum or maximum lengths for character strings used to
represent email addresses.
2.7. Dates and Times
Date and time attribute values MUST be represented in Universal
Coordinated Time (UTC) using the Gregorian calendar. The extended
date-time form using upper case "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
lower case "T" and "Z" characters.
Hollenbeck Standards Track [Page 6]RFC 4933 EPP Contact Mapping May 2007
2.8. Authorization Information
Authorization information is associated with contact objects to
facilitate transfer operations. Authorization information is
assigned when a contact object is created, and it might be updated in
the future. This specification describes password-based
authorization information, though other mechanisms are possible.
2.9. Disclosure of Data Elements and Attributes
The EPP core protocol requires a server operator to announce data
collection policies to clients; see Section 2.4 of [RFC4930]. In
conjunction with this disclosure requirement, this mapping includes
data elements that allow a client to identify elements that require
exceptional server operator handling to allow or restrict disclosure
to third parties.
A server operator announces a default disclosure policy when
establishing a session with a client. When an object is created or
updated, the client can specify contact attributes that require
exceptional disclosure handling using an OPTIONAL <contact:disclose>
element. Once set, disclosure preferences can be reviewed using a
contact information query. A server operator MUST reject any
transaction that requests disclosure practices that do not conform to
the announced data collection policy with a 2308 error response code.
If present, the <contact:disclose> element MUST contain a "flag"
attribute. The "flag" attribute contains an XML Schema boolean
value. A value of "true" or "1" (one) notes a client preference to
allow disclosure of the specified elements as an exception to the
stated data collection policy. A value of "false" or "0" (zero)
notes a client preference to not allow disclosure of the specified
elements as an exception to the stated data collection policy.
The <contact:disclose> element MUST contain at least one of the
following child elements:
<contact:name type="int"/>
<contact:name type="loc"/>
<contact:org type="int"/>
<contact:org type="loc"/>
<contact:addr type="int"/>
<contact:addr type="loc"/>
<contact:voice/>
<contact:fax/>
<contact:email/>
Hollenbeck Standards Track [Page 7]
RFC 4933 EPP Contact Mapping May 2007
Example <contact:disclose> element, flag="0":
<contact:disclose flag="0">
<contact:email/>
<contact:voice/>
</contact:disclose>
In this example, the contact email address and voice telephone number
cannot be disclosed. All other elements are subject to disclosure in
accordance with the server's data collection policy.
Example <contact:disclose> element, flag="1":
<contact:disclose flag="1">
<contact:name type="int"/>
<contact:org type="int"/>
<contact:addr type="int"/>
</contact:disclose>
In this example, the internationalized contact name, organization,
and address information can be disclosed. All other elements are
subject to disclosure in accordance with the server's data collection
policy.
Client identification features provided by the EPP <login> command
and contact authorization information are used to determine if a
client is authorized to perform contact information query commands.
These features also determine if a client is authorized to receive
data that is otherwise marked for non-disclosure in a query response.
3. EPP Command Mapping
A detailed description of the EPP syntax and semantics can be found
in [RFC4930]. The command mappings described here are specifically
for use in provisioning and managing contact objects via EPP.
3.1. EPP Query Commands
EPP provides three commands to retrieve contact information: <check>
to determine if a contact object can be provisioned within a
repository, <info> to retrieve detailed information associated with a
contact object, and <transfer> to retrieve contact object transfer
status information.
Hollenbeck Standards Track [Page 8]RFC 4933 EPP Contact Mapping May 2007
3.1.1. 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 a <contact:check> element that identifies the contact
namespace. The <contact:check> element contains the following child
elements:
- One or more <contact:id> elements that contain the server-unique
identifier of the contact objects to be queried.
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: <contact:check
C: xmlns:contact="urn:ietf:params:xml:ns:contact-1.0">
C: <contact:id>sh8013</contact:id>
C: <contact:id>sah8013</contact:id>
C: <contact:id>8013sah</contact:id>
C: </contact: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 <contact:chkData> element that
identifies the contact namespace. The <contact:chkData> element
contains one or more <contact:cd> elements that contain the following
child elements:
- A <contact: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.
Hollenbeck Standards Track [Page 9]RFC 4933 EPP Contact Mapping May 2007
- An OPTIONAL <contact: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 MAY be present to identify the language if the
negotiated value is something other than the default value of "en"
(English).
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>Command completed successfully</msg>
S: </result>
S: <resData>
S: <contact:chkData
S: xmlns:contact="urn:ietf:params:xml:ns:contact-1.0">
S: <contact:cd>
S: <contact:id avail="1">sh8013</contact:id>
S: </contact:cd>
S: <contact:cd>
S: <contact:id avail="0">sah8013</contact:id>
S: <contact:reason>In use</contact:reason>
S: </contact:cd>
S: <contact:cd>
S: <contact:id avail="1">8013sah</contact:id>
S: </contact:cd>
S: </contact: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.
Hollenbeck Standards Track [Page 10]RFC 4933 EPP Contact Mapping May 2007
3.1.2. EPP <info> Command
The EPP <info> command is used to retrieve information associated
with a contact object. In addition to the standard EPP command
elements, the <info> command MUST contain a <contact:info> element
that identifies the contact namespace. The <contact:info> element
contains the following child elements:
- A <contact:id> element that contains the server-unique identifier
of the contact object to be queried.
- An OPTIONAL <contact:authInfo> element that contains authorization
information associated with the contact object. If this element
is not provided or if the authorization information is invalid,
server policy determines if the command is rejected or if response
information will be returned to the client.
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: <contact:info
C: xmlns:contact="urn:ietf:params:xml:ns:contact-1.0">
C: <contact:id>sh8013</contact:id>
C: <contact:authInfo>
C: <contact:pw>2fooBAR</contact:pw>
C: </contact:authInfo>
C: </contact: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 <contact:infData> element that
identifies the contact namespace. The <contact:infData> element
contains the following child elements:
- A <contact:id> element that contains the server-unique identifier
of the contact object.
- A <contact:roid> element that contains the Repository Object
IDentifier assigned to the contact object when the object was
created.
Hollenbeck Standards Track [Page 11]RFC 4933 EPP Contact Mapping May 2007
- One or more <contact:status> elements that describe the status of
the contact object.
- One or two <contact: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 UTF-8 that can
be represented in the 7-bit US-ASCII character set. If a
localized form (type="loc") is provided, element content MAY be
represented in unrestricted UTF-8. The <contact:postalInfo>
element contains the following child elements:
- A <contact:name> element that contains the name of the
individual or role represented by the contact.
- An OPTIONAL <contact:org> element that contains the name of the
organization with which the contact is affiliated.
- A <contact:addr> element that contains address information
associated with the contact. A <contact:addr> element contains
the following child elements:
- One, two, or three OPTIONAL <contact:street> elements that
contain the contact's street address.
- A <contact:city> element that contains the contact's city.
- An OPTIONAL <contact:sp> element that contains the contact's
state or province.
- An OPTIONAL <contact:pc> element that contains the contact's
postal code.
- A <contact:cc> element that contains the contact's country
code.
- An OPTIONAL <contact:voice> element that contains the contact's
voice telephone number.
- An OPTIONAL <contact:fax> element that contains the contact's
facsimile telephone number.
- A <contact:email> element that contains the contact's email
address.
Hollenbeck Standards Track [Page 12]RFC 4933 EPP Contact Mapping May 2007
- A <contact:clID> element that contains the identifier of the
sponsoring client.
- A <contact:crID> element that contains the identifier of the
client that created the contact object.
- A <contact:crDate> element that contains the date and time of
contact object creation.
- A <contact:upID> element that contains the identifier of the
client that last updated the contact object. This element MUST
NOT be present if the contact has never been modified.
- A <contact:upDate> element that contains the date and time of the
most recent contact object modification. This element MUST NOT be
present if the contact object has never been modified.
- A <contact:trDate> element that contains the date and time of the
most recent successful contact object transfer. This element MUST
NOT be provided if the contact object has never been transferred.
- A <contact:authInfo> element that contains authorization
information associated with the contact object. This element MUST
NOT be provided if the querying client is not the current
sponsoring client.
- An OPTIONAL <contact:disclose> element that identifies elements
that require exceptional server operator handling to allow or
restrict disclosure to third parties. See Section 2.9 for a
description of the child elements contained within the <contact:
disclose> element.

An EPP error response MUST be returned if an <info> command cannot be
processed for any reason.
3.1.3. EPP <transfer> Query Command
The EPP <transfer> command provides a query operation that allows a
client to determine real-time status of pending and completed
transfer requests. In addition to the standard EPP command elements,
the <transfer> command MUST contain an "op" attribute with value
"query", and a <contact:transfer> element that identifies the contact
namespace. The <contact:transfer> element MUST contain the following
child elements:
Hollenbeck Standards Track [Page 14]
RFC 4933 EPP Contact Mapping May 2007
- A <contact:id> element that contains the server-unique identifier
of the contact object to be queried.
- An OPTIONAL <contact:authInfo> element that contains authorization
information associated with the contact object. If this element
is not provided or if the authorization information is invalid,
server policy determines whether the command is rejected or the
response information will be returned to the client.
Example <transfer> query 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: <transfer op="query">
C: <contact:transfer
C: xmlns:contact="urn:ietf:params:xml:ns:contact-1.0">
C: <contact:id>sh8013</contact:id>
C: <contact:authInfo>
C: <contact:pw>2fooBAR</contact:pw>
C: </contact:authInfo>
C: </contact:transfer>
C: </transfer>
C: <clTRID>ABC-12345</clTRID>
C: </command>
C:</epp>
When a <transfer> query command has been processed successfully, the
EPP <resData> element MUST contain a child <contact:trnData> element
that identifies the contact namespace. The <contact:trnData> element
contains the following child elements:
- A <contact:id> element that contains the server-unique identifier
for the queried contact.
- A <contact:trStatus> element that contains the state of the most
recent transfer request.
- A <contact:reID> element that contains the identifier of the
client that requested the object transfer.
- A <contact:reDate> element that contains the date and time that
the transfer was requested.
- A <contact:acID> element that contains the identifier of the
client that SHOULD act upon a PENDING transfer request. For all
other status types, the value identifies the client that took the
indicated action.
Hollenbeck Standards Track [Page 15]RFC 4933 EPP Contact Mapping May 2007
- A <contact:acDate> element that contains the date and time of a
required or completed response. For a pending request, the value
identifies the date and time by which a response is required
before an automated response action SHOULD be taken by the server.
For all other status types, the value identifies the date and time
when the request was completed.

An EPP error response MUST be returned if a <transfer> query command
cannot be processed for any reason.
3.2. EPP Transform Commands
EPP provides four commands to transform contact object information:
<create> to create an instance of a contact object, <delete> to
delete an instance of a contact object, <transfer> to manage contact
object sponsorship changes, and <update> to change information
associated with a contact object. This document does not define a
mapping for the EPP <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
Hollenbeck Standards Track [Page 16]RFC 4933 EPP Contact Mapping May 2007
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
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, all clients involved in the transaction
MUST be notified using a service message that the action has been
completed and that the status of the object has changed.
3.2.1. EPP <create> Command
The EPP <create> command provides a transform operation that allows a
client to create a contact object. In addition to the standard EPP
command elements, the <create> command MUST contain a <contact:
create> element that identifies the contact namespace. The <contact:
create> element contains the following child elements:
- A <contact:id> element that contains the desired server-unique
identifier for the contact to be created.
- One or two <contact: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 UTF-8 that can
be represented in the 7-bit US-ASCII character set. If a
localized form (type="loc") is provided, element content MAY be
represented in unrestricted UTF-8. The <contact:postalInfo>
element contains the following child elements:
- A <contact:name> element that contains the name of the
individual or role represented by the contact.
- An OPTIONAL <contact:org> element that contains the name of the
organization with which the contact is affiliated.
- A <contact:addr> element that contains address information
associated with the contact. A <contact:addr> element contains
the following child elements:
- One, two, or three OPTIONAL <contact:street> elements that
contain the contact's street address.
- A <contact:city> element that contains the contact's city.
Hollenbeck Standards Track [Page 17]RFC 4933 EPP Contact Mapping May 2007
- An OPTIONAL <contact:sp> element that contains the contact's
state or province.
- An OPTIONAL <contact:pc> element that contains the contact's
postal code.
- A <contact:cc> element that contains the contact's country
code.
- An OPTIONAL <contact:voice> element that contains the contact's
voice telephone number.
- An OPTIONAL <contact:fax> element that contains the contact's
facsimile telephone number.
- A <contact:email> element that contains the contact's email
address.
- A <contact:authInfo> element that contains authorization
information to be associated with the contact object. This
mapping includes a password-based authentication mechanism, but
the schema allows new mechanisms to be defined in new schemas.
- An OPTIONAL <contact:disclose> element that allows a client to
identify elements that require exceptional server operator
handling to allow or restrict disclosure to third parties. See
Section 2.9 for a description of the child elements contained
within the <contact:disclose> element.

When a <create> command has been processed successfully, the EPP
<resData> element MUST contain a child <contact:creData> element that
identifies the contact namespace. The <contact:creData> element
contains the following child elements:
- A <contact:id> element that contains the server-unique identifier
for the created contact.
- A <contact:crDate> element that contains the date and time of
contact object creation.

An EPP error response MUST be returned if a <create> command cannot
be processed for any reason.
3.2.2. EPP <delete> Command
The EPP <delete> command provides a transform operation that allows a
client to delete a contact object. In addition to the standard EPP
command elements, the <delete> command MUST contain a <contact:
delete> element that identifies the contact namespace. The <contact:
delete> element MUST contain the following child element:
- A <contact:id> element that contains the server-unique identifier
of the contact object to be deleted.
A contact object SHOULD NOT be deleted if it is associated with other
known objects. An associated contact SHOULD NOT be deleted until
associations with other known objects have been broken. A server
SHOULD notify clients of object relationships when a <delete> command
is attempted and fails due to existing object relationships.
Hollenbeck Standards Track [Page 20]RFC 4933 EPP Contact Mapping May 2007
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>
C: <contact:delete

C: </contact:delete>
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.
Example <delete> response:
S:<?xml version="1.0" encoding="UTF-8" standalone="no"?>
S:<epp xmlns="urn:ietf:params:xml:ns:epp-1.0">

S: </trID>
S: </response>
S:</epp>
An EPP error response MUST be returned if a <delete> command cannot
be processed for any reason.
3.2.3. EPP <renew> Command
Renewal semantics do not apply to contact objects, so there is no
mapping defined for the EPP <renew> command.
Hollenbeck Standards Track [Page 21]
RFC 4933 EPP Contact Mapping May 2007
3.2.4. EPP <transfer> Command
The EPP <transfer> command provides a transform operation that allows
a client to manage requests to transfer the sponsorship of a contact
object. In addition to the standard EPP command elements, the
<transfer> command MUST contain a <contact:transfer> element that
identifies the contact namespace. The <contact:transfer> element
contains the following child elements:
- A <contact:id> element that contains the server-unique identifier
of the contact object for which a transfer request is to be
created, approved, rejected, or cancelled.
- A <contact:authInfo> element that contains authorization
information associated with the contact object.
Every EPP <transfer> command MUST contain an "op" attribute that
identifies the transfer operation to be performed as defined in
[RFC4930].
Example <transfer> request 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: <transfer op="request">
C: <contact:transfer
C: xmlns:contact="urn:ietf:params:xml:ns:contact-1.0">
C: <contact:id>sh8013</contact:id>
C: <contact:authInfo>
C: <contact:pw>2fooBAR</contact:pw>
C: </contact:authInfo>
C: </contact:transfer>
C: </transfer>
C: <clTRID>ABC-12345</clTRID>
C: </command>
C:</epp>
When a <transfer> command has been processed successfully, the EPP
<resData> element MUST contain a child <contact:trnData> element that
identifies the contact namespace. The <contact:trnData> element
contains the same child elements defined for a <transfer> query
response.
Hollenbeck Standards Track [Page 22]RFC 4933 EPP Contact Mapping May 2007
Example <transfer> response:
S:<?xml version="1.0" encoding="UTF-8" standalone="no"?>

S: </response>
S:</epp>
An EPP error response MUST be returned if a <transfer> command cannot
be processed for any reason.
3.2.5. EPP <update> Command
The EPP <update> command provides a transform operation that allows a
client to modify the attributes of a contact object. In addition to
the standard EPP command elements, the <update> command MUST contain
a <contact:update> element that identifies the contact namespace.
The <contact:update> element contains the following child elements:
- A <contact:id> element that contains the server-unique identifier
of the contact object to be updated.
- An OPTIONAL <contact:add> element that contains attribute values
to be added to the object.
- An OPTIONAL <contact:rem> element that contains attribute values
to be removed from the object.
- An OPTIONAL <contact:chg> element that contains object attribute
values to be changed.
Hollenbeck Standards Track [Page 23]RFC 4933 EPP Contact Mapping May 2007
At least one <contact:add>, <contact:rem>, or <contact: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
<contact:add> and <contact:rem> elements contain the following child
elements:
- One or more <contact:status> elements that contain status values
to be associated with or removed from the object. When specifying
a value to be removed, only the attribute value is significant;
element text is not required to match a value for removal.
A <contact:chg> element contains the following OPTIONAL child
elements. At least one child element MUST be present:
- One or two <contact: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 UTF-8 that can
be represented in the 7-bit US-ASCII character set. If a
localized form (type="loc") is provided, element content MAY be
represented in unrestricted UTF-8. The <contact:postalInfo>
element contains the following OPTIONAL child elements:
- A <contact:name> element that contains the name of the
individual or role represented by the contact.
- A <contact:org> element that contains the name of the
organization with which the contact is affiliated.
- A <contact:addr> element that contains address information
associated with the contact. A <contact:addr> element contains
the following child elements:
- One, two, or three OPTIONAL <contact:street> elements that
contain the contact's street address.
- A <contact:city> element that contains the contact's city.
- An OPTIONAL <contact:sp> element that contains the contact's
state or province.
- An OPTIONAL <contact:pc> element that contains the contact's
postal code.
- A <contact:cc> element that contains the contact's country
code.
Hollenbeck Standards Track [Page 24]RFC 4933 EPP Contact Mapping May 2007
- A <contact:voice> element that contains the contact's voice
telephone number.
- A <contact:fax> element that contains the contact's facsimile
telephone number.
- A <contact:email> element that contains the contact's email
address.
- A <contact:authInfo> element that contains authorization
information associated with the contact object. This mapping
includes a password-based authentication mechanism, but the schema
allows new mechanisms to be defined in new schemas.
- A <contact:disclose> element that allows a client to identify
elements that require exceptional server operator handling to
allow or restrict disclosure to third parties. See Section 2.9
for a description of the child elements contained within the
<contact:disclose> element.

3.3. 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 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.

The status of the contact 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 either
by queuing a service message for retrieval via the <poll> command or
by using an out-of-band mechanism to inform the client of the
request.
The service message MUST contain text in the <response>, <msgQ>,
<msg> element that describes the notification. In addition, the EPP
<resData> element MUST contain a child <contact:panData> element that
identifies the contact namespace. The <contact:panData> element
contains the following child elements:
- A <contact:id> element that contains the server-unique identifier
of the contact object. The <contact: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.
- A <contact: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.
- A <contact:paDate> element that contains the date and time
describing when review of the requested action was completed.

4. 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.

5. Internationalization Considerations
EPP is represented in XML, which provides native support for encoding
information using the Unicode character set and its more compact
representations, including UTF-8. Conformant XML processors
recognize both UTF-8 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
REQUIRED with this specification.
All date-time values presented via EPP MUST be expressed in Universal
Coordinated Time using the Gregorian calendar. The XML Schema allows
use of time zone identifiers to indicate offsets from the zero
meridian, but this option MUST NOT be used with EPP. The extended
date-time form using upper case "T" and "Z" characters defined in
[W3C.REC-xmlschema-2-20041028] MUST be used to represent date-time
values as the XML Schema does not support truncated date-time forms
or lower case "T" and "Z" characters.
Humans, organizations, and other entities often need to represent
social information in both a commonly understood character set and a
locally optimized character set. This specification provides
features allowing representation of social information in both a
subset of UTF-8 for broad readability and unrestricted UTF-8 for
local optimization.
6. IANA Considerations
This document uses URNs to describe XML namespaces and XML schemas
conforming to a registry mechanism described in [RFC3688]. Two URI
assignments have been registered by the IANA.
Registration request for the contact namespace:
URI: urn:ietf:params:xml:ns:contact-1.0
Registrant Contact: See the "Author's Address" section of this
document.
XML: None. Namespace URIs do not represent an XML specification.
Registration request for the contact XML schema:
URI: urn:ietf:params:xml:schema:contact-1.0
Registrant Contact: See the "Author's Address" section of this
document.
Hollenbeck Standards Track [Page 38]
RFC 4933 EPP Contact Mapping May 2007
XML: See the "Formal Syntax" section of this document.
7. Security Considerations
Authorization information as described in Section 2.8 is REQUIRED to
create a contact object. This information is used in some query and
transfer operations as an additional means of determining client
authorization to perform the command. Failure to protect
authorization information from inadvertent disclosure can result in
unauthorized transfer operations and unauthorized information
release. Both client and server MUST ensure that authorization
information is stored and exchanged with high-grade encryption
mechanisms to provide privacy services.
The object mapping described in this document does not provide any
other security services or introduce any additional considerations
beyond those described by [RFC4930] and protocol layers used by EPP.

Appendix A. Changes from RFC 3733
1. Minor reformatting as a result of converting I-D source format
from nroff to XML.
2. Removed this text from Section 2.2:
"With one exception, transform commands MUST be rejected when a
pendingCreate, pendingDelete, pendingTransfer, or pendingUpdate
status is set. The only exception is that a <transfer> command
to approve, reject, or cancel a transfer MAY be processed while
an object is in "pendingTransfer" status."
3. Fixed examples in Section 2.9 (added missing "/" characters).
4. Changed text in Section 3.1.3 from "A <contact:acID> element
that contains the identifier of the client that SHOULD act upon
the transfer request" to "A <contact:acID> element that contains
the identifier of the client that SHOULD act upon a PENDING
transfer request. For all other status types, the value
identifies the client that took the indicated action".
5. Fixed the example response in Section 3.2.4 to use the correct
response code and response text.
6. Changed text in Section 3.2.5 from "At least one <contact:add>,
<contact:rem>, or <contact:chg> element MUST be provided." to
"At least one <contact:add>, <contact:rem>, or <contact: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."
7. Changed text in Section 3.3 (old Section 3.2.6) from this:
"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."
to this:
"The server operator reviews the request offline, and informs
the client of the outcome of the review either by queuing a
service message for retrieval via the <poll> command or by using
an out-of-band mechanism to inform the client of the request."
8. Removed text describing use of the XML Schema schemaLocation
attribute. This is an optional attribute that doesn't need to
be mandated for use in EPP.
Hollenbeck Standards Track [Page 41]RFC 4933 EPP Contact Mapping May 2007
9. Updated text describing a requirement to use UTF-8 encoding in
the "Internationalization Considerations" section.
10. Removed references to RFC 3339 and replaced them with references
to the W3C XML Schema specification.
11. Updated the E.164 reference.
12. Updated EPP and XML references. Updated reference from RFC 2279
to RFC 3629.
