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 [XML] and XML Schema notation as
 described in [XMLS-1] and [XMLS-2].
 [RFC3730] 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 is provided only to illustrate element
 relationships and is not a REQUIRED feature of this protocol.

Hollenbeck Standards Track [Page 2] RFC 3733 EPP Contact Mapping March 2004

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
 [RFC3730].

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:
  1. clientDeleteProhibited, serverDeleteProhibited
 Requests to delete the object MUST be rejected.
  1. clientTransferProhibited, serverTransferProhibited
 Requests to transfer the object MUST be rejected.

Hollenbeck Standards Track [Page 3] RFC 3733 EPP Contact Mapping March 2004

  1. clientUpdateProhibited, serverUpdateProhibited
 Requests to update the object (other than to remove this status) MUST
 be rejected.
  1. 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.
  1. 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.
  1. pendingCreate, pendingDelete, 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.
 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.
 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.

Hollenbeck Standards Track [Page 4] RFC 3733 EPP Contact Mapping March 2004

 "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 [RFC2279] 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
 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 [ISO3166].

2.5. Telephone Numbers

 Contact telephone number structure is derived from structures defined
 in [E164a].  Telephone numbers described in this mapping are
 character strings that MUST begin with a plus sign ("+", ASCII value

Hollenbeck Standards Track [Page 5] RFC 3733 EPP Contact Mapping March 2004

 0x002B), followed by a country code defined in [E164b], 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 [RFC2822].  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
 [RFC3339] 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.

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 [RFC3730].  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.

Hollenbeck Standards Track [Page 6] RFC 3733 EPP Contact Mapping March 2004

 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" (decimal 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" (decimal 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>
 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
 can not 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.

Hollenbeck Standards Track [Page 7] RFC 3733 EPP Contact Mapping March 2004

 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 [RFC3730].  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.

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 and the location of the contact schema.  The
 <contact:check> element contains the following child elements:
  1. 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:     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 C:     xsi:schemaLocation="urn:ietf:params:xml:ns:epp-1.0
 C:     epp-1.0.xsd">
 C:  <command>
 C:    <check>
 C:      <contact:check
 C:       xmlns:contact="urn:ietf:params:xml:ns:contact-1.0"
 C:       xsi:schemaLocation="urn:ietf:params:xml:ns:contact-1.0

Hollenbeck Standards Track [Page 8] RFC 3733 EPP Contact Mapping March 2004

 C:       contact-1.0.xsd">
 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 and the location of the contact
 schema.  The <contact:chkData> element contains one or more
 <contact:cd> elements that contain the following child elements:
  1. 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 can not be provisioned.
  1. An OPTIONAL <contact:reason> element that MAY be provided when an

object can not be provisioned. If present, this element contains

    server-specific text to help explain why the object can not 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:     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

 S:     epp-1.0.xsd">
 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:       xsi:schemaLocation="urn:ietf:params:xml:ns:contact-1.0
 S:       contact-1.0.xsd">

 S:        </contact:cd>
 S:        <contact:cd>
 S:          <contact:id avail="0">sah8013</contact:id>

 S:      <svTRID>54322-XYZ</svTRID>
 S:    </trID>
 S:  </response>
 S:</epp>
 An EPP error response MUST be returned if a <check> command can not
 be processed for any reason.

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 and the location of the contact
 schema.  The <contact:info> element contains the following child
 elements:
  1. A <contact:id> element that contains the server-unique identifier

of the contact object to be queried.

  1. 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:     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

 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 and the location of the contact
 schema.  The <contact:infData> element contains the following child
 elements:
  1. A <contact:id> element that contains the server-unique identifier

of the contact object.

  1. A <contact:roid> element that contains the Repository Object

IDentifier assigned to the contact object when the object was

    created.
  1. One or more <contact:status> elements that describe the status of

the contact object.

  1. 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:
  1. A <contact:name> element that contains the name of the

individual or role represented by the contact.

  1. An OPTIONAL <contact:org> element that contains the name of the

organization with which the contact is affiliated.

Hollenbeck Standards Track [Page 11] RFC 3733 EPP Contact Mapping March 2004

  1. A <contact:addr> element that contains address information

associated with the contact. A <contact:addr> element contains

       the following child elements:
  1. One, two, or three OPTIONAL <contact:street> elements that

contain the contact's street address.

  1. A <contact:city> element that contains the contact's city.
  1. An OPTIONAL <contact:sp> element that contains the contact's

state or province.

  1. An OPTIONAL <contact:pc> element that contains the contact's

postal code.

  1. A <contact:cc> element that contains the contact's country

code.

  1. An OPTIONAL <contact:voice> element that contains the contact's

voice telephone number.

  1. An OPTIONAL <contact:fax> element that contains the contact's

facsimile telephone number.

  1. A <contact:email> element that contains the contact's email

address.

  1. A <contact:clID> element that contains the identifier of the

sponsoring client.

  1. A <contact:crID> element that contains the identifier of the

client that created the contact object.

  1. A <contact:crDate> element that contains the date and time of

contact object creation.

  1. 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.
  1. 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.
  1. 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.

Hollenbeck Standards Track [Page 12] RFC 3733 EPP Contact Mapping March 2004

  1. 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.
  1. 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 can not
 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 and the location of the contact schema.  The
 <contact:transfer> element MUST contain the following child elements:
  1. A <contact:id> element that contains the server-unique identifier

of the contact object to be queried.

  1. 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:     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

 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 and the location of the contact
 schema.  The <contact:trnData> element contains the following child
 elements:
  1. A <contact:id> element that contains the server-unique identifier

for the queried contact.

  1. A <contact:trStatus> element that contains the state of the most

recent transfer request.

  1. A <contact:reID> element that contains the identifier of the

client that requested the object transfer.

  1. A <contact:reDate> element that contains the date and time that

the transfer was requested.

  1. A <contact:acID> element that contains the identifier of the

client that SHOULD act upon the transfer request.

  1. 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
 can not 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
 review is required before the requested action can be completed.  In
 such situations the server MUST return a 1001 response code to the

Hollenbeck Standards Track [Page 16] RFC 3733 EPP Contact Mapping March 2004

 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 and
 the location of the contact schema.  The <contact:create> element
 contains the following child elements:
  1. A <contact:id> element that contains the desired server-unique

identifier for the contact to be created.

  1. 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:
  1. A <contact:name> element that contains the name of the

individual or role represented by the contact.

  1. An OPTIONAL <contact:org> element that contains the name of the

organization with which the contact is affiliated.

  1. A <contact:addr> element that contains address information

associated with the contact. A <contact:addr> element contains

       the following child elements:
  1. One, two, or three OPTIONAL <contact:street> elements that

contain the contact's street address.

  1. A <contact:city> element that contains the contact's city.
  1. An OPTIONAL <contact:sp> element that contains the contact's

state or province.

Hollenbeck Standards Track [Page 17] RFC 3733 EPP Contact Mapping March 2004

  1. An OPTIONAL <contact:pc> element that contains the contact's

postal code.

  1. A <contact:cc> element that contains the contact's country

code.

  1. An OPTIONAL <contact:voice> element that contains the contact's

voice telephone number.

  1. An OPTIONAL <contact:fax> element that contains the contact's

facsimile telephone number.

  1. A <contact:email> element that contains the contact's email

address.

  1. 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.
  1. 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.

 elements:
  1. A <contact:id> element that contains the server-unique identifier

for the created contact.

  1. A <contact:crDate> element that contains the date and time of

contact object creation.

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 and
 the location of the contact schema.  The <contact:delete> element
 MUST contain the following child element:
  1. 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.
 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:     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

 S:</epp>
 An EPP error response MUST be returned if a <delete> command can not
 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.

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 and the location of the contact
 schema.  The <contact:transfer> element contains the following child
 elements:
  1. 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.

Hollenbeck Standards Track [Page 21] RFC 3733 EPP Contact Mapping March 2004

  1. 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
    [RFC3730].
 Example <transfer> request command:
 C:<?xml version="1.0" encoding="UTF-8" standalone="no"?>

 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 and the location of the contact
 schema.  The <contact:trnData> element contains the same child
 elements defined for a transfer query response.

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 and
 the location of the contact schema.  The <contact:update> element
 contains the following child elements:
  1. A <contact:id> element that contains the server-unique identifier

of the contact object to be updated.

  1. An OPTIONAL <contact:add> element that contains attribute values

to be added to the object.

  1. An OPTIONAL <contact:rem> element that contains attribute values

to be removed from the object.

  1. An OPTIONAL <contact:chg> element that contains object attribute

values to be changed.

 At least one <contact:add>, <contact:rem>, or <contact:chg> element
 MUST be provided.  The <contact:add> and <contact:rem> elements
 contain the following child elements:

Hollenbeck Standards Track [Page 23] RFC 3733 EPP Contact Mapping March 2004

  1. 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:
  1. 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

    element contains the following OPTIONAL child elements:
  1. A <contact:name> element that contains the name of the

individual or role represented by the contact.

  1. A <contact:org> element that contains the name of the

organization with which the contact is affiliated.

  1. A <contact:addr> element that contains address information

associated with the contact. A <contact:addr> element contains

       the following child elements:
  1. One, two, or three OPTIONAL <contact:street> elements that

contain the contact's street address.

  1. A <contact:city> element that contains the contact's city.
  1. An OPTIONAL <contact:sp> element that contains the contact's

state or province.

  1. An OPTIONAL <contact:pc> element that contains the contact's

postal code.

  1. A <contact:cc> element that contains the contact's country

code.

  1. A <contact:voice> element that contains the contact's voice

telephone number.

Hollenbeck Standards Track [Page 24] RFC 3733 EPP Contact Mapping March 2004

  1. A <contact:fax> element that contains the contact's facsimile

telephone number.

  1. A <contact:email> element that contains the contact's email

address.

  1. 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.
  1. 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.

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

3.2.6. 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

Hollenbeck Standards Track [Page 26] RFC 3733 EPP Contact Mapping March 2004

 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:    </trID>
 S:  </response>
 S:</epp>
 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 by
 queuing a service message for retrieval via the <poll> command.
 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 and the location of the contact
 schema.  The <contact:panData> element contains the following child
 elements:
  1. 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

Hollenbeck Standards Track [Page 27] RFC 3733 EPP Contact Mapping March 2004

    boolean value indicates that the request has been denied and the
    requested action has not been taken.
  1. 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.
  1. A <contact:paDate> element that contains the date and time

describing when review of the requested action was completed.

 Example "review completed" service message:

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
 RECOMMENDED in environments where parser encoding support
 incompatibility exists.
 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
 [RFC3339] 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.
 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 [RFC3730] and protocol layers used by EPP.
