1.  Introduction

   When creating a domain name which will be stored in a shared central
   repository, some registry administrative organizations require the
   verification of the domain name and the real name based on legal or
   policy requirements.

   The domain name verification, means to verify the domain label is in
   compliance with laws, rules and regulations.  The real name
   verification, means to verify that the registrant really exists and
   is authorized to register a domain name.

   The verification of this document meets the requirements in China,
   but MAY be applicable outside of China.

   In order to meet above requirements of the domain name registration,
   this document describes the Extensible Provisioning Protocol (EPP)
   Name Verification (NV) Mapping.  This document 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].

   The EPP core protocol specification [RFC5730] 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.

2.  Terminology

   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].

   "nv-1.0" in this document is used as an abbreviation for
   urn:ietf:params:xml:ns:nv-1.0.  The XML namespace prefix "nv" is
   used, but implementations MUST NOT depend on it and instead employ a
   proper namespace-aware XML parser and serializer to interpret and
   output the XML documents.

   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 to develop a conforming implementation.

3.  Definitions and Object Attributes

3.1.  Definitions

   The following definitions are used in this document:

   o  Domain Name Verification(DNV), represents the verification of the
      domain's label is in compliance with laws, rules and regulations.

   o  Real Name Verification(RNV), represents the verification of the
      registrant(real name) is in compliance with laws, rules and
      regulations.

   o  Name Verification(NV), represents DNV, RNV or both of them.

   o  Verification Service Provider(VSP), collects the proof of
      materials for Name Verification(NV) and performs the verification.

   o  Verification Code, which is described in
      [I-D.gould-eppext-verificationcode] ,is a formatted token,
      referred to as the Verification Code Token, that is digitally
      signed by a Verification Service Provider (VSP) using XML
      Signature in "W3C.CR-xmldsig-core2-20120124".

   o  Signed Code, which is described in
      [I-D.gould-eppext-verificationcode], is the XML Signature format
      of the Verification Code.

   o  Encoded Signed Code, which is described in
      [I-D.gould-eppext-verificationcode], is the "base64" encoded XML
      Signature format of the Verification Code.

   o  Prohibited Name(PN), is a domain label that is prohibited from
      registration.

   o  Restricted Name(RN), is a domain label that is restricted from
      registration.  Additional information is needed during Domain Name
      Verification(DNV) to authorize the registration of a Restricted
      Name.

3.2.  Object Attributes

   An EPP NV 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.

   o  Status Values.  A NV object MUST always have one associated status
      value.  The Status value can be set only by the server.  The
      status value MAY be accompanied by a string of human-readable text
      that describes the rationale for the status applied to the object.
      The status of an object MAY change as a result of an action
      performed by a server operator.  Status Value Descriptions:

      *  pendingCompliant.  The object verification is not complete and
         is pending completion.  Please refer to Section 4.3 for details
         on handling offline review of NV objects with the
         pendingComplaint status.

      *  compliant.  The object is in compliance with the policy.

      *  nonCompliant.  The object is not in compliance with the policy.

   o  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.

   o  Authorization Information.  Authorization information is
      associated with NV objects to facilitate query operations.
      Authorization information is assigned when a NV object is created,
      and it might be updated in the future.  This specification
      describes password-based authorization information, though other
      mechanisms are possible.

3.3.  Name Verification Proofs

   When performing name verification, some Verification Service
   Providers(VSP) MAY need to collect the proof of materials to verify
   the real name of a registrant.  The proof of materials is defined
   with the following enumerated values:

Internet-Draft               EPP NV Mapping                     May 2016


   o  "poc" for Proof of Citizen(POC).  The POC represents the citizen's
      identification card(ID) material.

   o  "poe" for Proof of Enterprise(POE).  The POE represents the
      Organization Code Certificate(OCC) or Business License(BL)
      material.

   o  "poot" for Proof of Other Types(POOT).  The POOT represents other
      certificate materials except the POC and POE.

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 NV via EPP.

4.1.  EPP Query Commands

   EPP provides three commands to retrieve NV information: <check>
   determine if an object is known to the server, <info> to retrieve
   detailed information associated with an object, and <transfer> to
   retrieve object transfer status information.

4.1.1.  EPP <check> Command

   The EPP <check> command is used to determine if the domain's label
   can be used to create a DNV object.  It provides a hint that allows a
   client to anticipate the success or failure of creating a DNV object
   using the <create> command.

   In addition to the standard EPP command elements, the <check> command
   MUST contain a <nv:check> element that identifies the nv namespace.
   The <nv:check> element contains the following child elements:

   o  One or more <nv:name> elements that contain the domain labels to
      be queried.

Internet-Draft               EPP NV Mapping                     May 2016


      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:      <nv:check xmlns:nv="urn:ietf:params:xml:ns:nv-1.0">
   C:        <nv:name>example1</nv:name>
   C:        <nv:name>example2</nv:name>
   C:        <nv:name>example3</nv:name>
   C:      </nv: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 <nv:chkData> element that
   identifies the NV namespace.  The <nv:chkData> element contains one
   or more <nv:cd>elements that contain the following child elements:

   o  A <nv:name> element that contains the queried domain label.  This
      element MUST contain an "avail" attribute whose value indicates
      object availability (can it be created or not) at the moment the
      <check> command was completed.  A value of "1" or "true" means
      that the object can be created.  A value of "0" or "false" means
      that the object can not be created.  This element SHOULD contain a
      "restricted" attribute whose value indicates this name is a RN or
      not, with a default value of "0".  A value of "1" or "true" means
      that the object is a RN Name.  A value of "0" or "false" means
      that the object is not restricted.

   o  An OPTIONAL <nv:reason> element that MAY be provided when an
      object cannot be created.  If present, this element contains
      server-specific text to help explain why the object cannot be
      created.  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:      <nv:chkData
   S:       xmlns:nv="urn:ietf:params:xml:ns:nv-1.0">
   S:        <nv:cd>
   S:          <nv:name avail="1">example1</nv:name>
   S:        </nv:cd>
   S:        <nv:cd>
   S:          <nv:name avail="0">example2</nv:name>
   S:          <nv:reason>In Prohibited Lists.</nv:reason>
   S:        </nv:cd>
   S:        <nv:cd>
   S:          <nv:name avail="0" restricted="1">example3</nv:name>
   S:        </nv:cd>
   S:      </nv:chkData>
   S:    </resData>
   S:    <trID>
   S:      <clTRID>ABC-12345</clTRID>
   S:      <svTRID>54322-XYZ</svTRID>
   S:    </trID>
   S:  </response>
   S:</epp>

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

4.1.2.  EPP <info> Command

   The EPP <info> command is used to retrieve information associated
   with a NV object.  The response to this command MAY vary depending on
   the identity of the querying client, and server policy towards
   unauthorized clients.  If the querying client is the sponsoring
   client, all available information MUST be returned.  If the querying
   client is not the sponsoring client but the client provides valid
   authorization information, all available information MUST be
   returned.  If the querying client is not the sponsoring client and
   the client does not provide valid authorization information, server
   policy determines which OPTIONAL elements are returned.

   In addition to the standard EPP command elements, the <info> command
   MUST contain a <nv:info> element that identifies the NV namespace.
   The <nv:info> element contains the following child elements:

   o  A <nv:code> element that contains the Verification Code Token
      value.  An "type" attribute MUST be used to identify the type of
      the query(Signed Code or Input Data).  If the type is
      "signedCode", the successful response of the server MUST be the
      Signed Code of the verification code.  If the type is "input", the
      successful response of the server MUST be the verification input
      data and the verification status.

   o  An OPTIONAL <nv:authInfo> element that contains authorization
      information associated with the NV 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.

   When an <info> command has been processed successfully, the EPP
   <resData> element MUST contain a child <nv:infData> element that
   identifies the nv namespace.  The <nv:infData> element has two forms
   based on the query type provided in the command: the Signed Code Form
   and the Input Form.  The child element of the <nv:infData> element is
   defined for each form.

   The Signed Code Form is returned when the command "type" attribute is
   set to "signedCode".  The <nv:signedCode> element is used for the
   Signed Code Form that contains the following child elements:

   o  A <nv:code> element that contains the Verification Code Token
      value of the signed code with the "type" attribute to indicate the
      type of NV object.  The "type" attribute value of "domain"
      indicates a DNV object and "real-name" indicates a RNV object.

   o  An OPTIONAL <nv:status> element that contains the current status
      using the status values defined in Section 3.2.

   o  A <nv:encodedSignedCode> element include:

      *  A <verificationCode:code>element that is a "base64" encoded
         form of the digitally signed <verificationCode:signedCode> as
         defined in [I-D.gould-eppext-verificationcode].

   A server with a different information-return policy MAY provide less
   information in a response for an unauthorized client.

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

4.1.3.  EPP <transfer> Command

   Transfer semantics do not apply to Name Verification (NV) objects, so
   there is no mapping defined for the EPP <transfer> command.

4.2.  EPP Transform Commands

   EPP provides five commands to transform NV objects: <create> to
   create an instance of an object, <delete> to delete an instance of an
   object, <renew> to extend the validity period of an object,
   <transfer> to manage object sponsorship changes, and <update> to
   change information associated with an object.

4.2.1.  EPP <create> Command

   The EPP <create> command provides a transform operation that allows a
   client to create an NV object.  In addition to the standard EPP
   command elements, the <create> command MUST contain a <nv:create>

   element that identifies the NV namespace.  The <nv:create> elements
   contains a choice of two different child elements dependent on the
   type of NV object to create.  The <nv:dnv> child element is used to
   create a DNV object and the <nv:rnv> child element is used to create
   a RNV object.  AN <nv:authInfo> element contains authorization
   information to be associated with the NV object.

   o  The <nv:dnv> element is used for a DNV object and contains the
      following child elements:

      *  A <nv:name> element that contains the label of the domain.

      *  An OPTIONAL <nv:rnvCode> element containing the Verification
         Code Token value of a RNV object used for verification of a
         Restricted Name.

   o  The <nv:rnv> element is used for a RNV object.  The "role"
      attribute MUST be used to identify the role of the RNV object with
      the possible values of "person" or "org".  The <nv:rnv> element
      contains the following child elements:

      *  A <nv:name> element that contains the full name of the contact.

      *  A <nv:num> element that contains the citizen or the
         organization ID of the contact.

      *  A <nv:proofType> element that contains the proof material type
         of the contact based on the enumerated values defined in Name
         Verification Proofs (Section 3.3).

      *  Zero or more <nv:document> elements that contains the following
         child elements:

         +  A <nv:fileType> element contains the type of the file.

         +  A <nv:fileContent> element contains the "base64" encoded
            content of the file.

      Example <create> command for a DNV object:

   When a <create> command has been processed successfully, the EPP
   <resData> element MUST contain a child <nv:creData> element that
   identifies the nv namespace. <nv:creData> element contains the either
   a <nv:success> element on success or a <nv:failed> element on
   failure.

   o  The <nv:success> element contains the following child elements:

      *  A <nv:code> element that contains the id of the verification
         code with the required "type" attribute that defines the type
         of the verification code.

      *  A <nv:status> element that contains the current status using
         the status values defined in Section 3.2.

      *  A <nv:crDate> element that contains the date and time of nv
         object creation.

      *  A <nv:encodedSignedCode> element include:

         +  A <verificationCode:code>element that is a "base64" encoded
            form of the digitally signed <verificationCode:signedCode>
            as defined in [I-D.gould-eppext-verificationcode].

   o  The <nv:failed> element contains the following child elements:

      *  A <nv:status> element that contains the current status using
         the status values defined in Section 3.2.

      *  A <nv:msg> element containing a human-readable description of
         the reason of the failure.  The language of the response is
         identified via an OPTIONAL "lang" attribute.  If not specified,
         the default attribute value MUST be "en" (English).

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

4.2.2.  EPP <delete> Command

   Delete semantics do not apply to Name Verification (NV) objects, so
   there is no mapping defined for the EPP <delete> command.

4.2.3.  EPP <renew> Command

   Renew semantics do not apply to Name Verification (NV) objects, so
   there is no mapping defined for the EPP <renew> command.

4.2.4.  EPP <transfer> Command

   Transfer semantics do not apply to Name Verification (NV) 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 a NV object.  In addition to the
   standard EPP command elements, the <update> command MUST contain a
   <nv:update> element that identifies the NV namespace.  The
   <nv:update> element contains the following child elements:

   o  A <nv:code> element that contains the code of the a NV object to
      be updated.

   o  A <nv:chg> element that contains object attribute values to be
      changed.

   A <nv:chg> element contains the following child elements:

Internet-Draft               EPP NV Mapping                     May 2016


   o  A <nv:authInfo> element that contains authorization information
      associated with the NV object.  This mapping includes a password-
      based authentication mechanism, but the schema allows new
      mechanisms to be defined in new schemas.

      Example <update> 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:    <update>
   C:      <nv:update xmlns:nv="urn:ietf:params:xml:ns:nv-1.0">
   C:        <nv:code>abc-123</nv:code>
   C:        <nv:chg>
   C:          <nv:authInfo>
   C:            <nv:pw>2BARfoo</nv:pw>
   C:          </nv:authInfo>
   C:        </nv:chg>
   C:      </nv:update>
   C:    </update>
   C:    <clTRID>ABC-12345</clTRID>
   C:  </command>
   C:</epp>

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

      Example <update> 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:    <trID>

   S:    </trID>
   S:  </response>

      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 that 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.

   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>Command completed successfully; action pending</msg>
   S:    </result>
   S:    <resData>
   S:      <nv:creData
   S:       xmlns:nv="urn:ietf:params:xml:ns:nv-1.0">
   S:        <nv:pending>
   S:          <nv:code type="domain">abc-123</nv:code>
   S:          <nv:status s="pendingCompliant"/>
   S:          <nv:crDate>2015-09-03T22:00:00.0Z</nv:crDate>
   S:        </nv:pending>
   S:      </nv:creData>
   S:    </resData>
   S:    <trID>
   S:      <clTRID>ABC-12345</clTRID>
   S:      <svTRID>54321-XYZ</svTRID>
   S:    </trID>
   S:  </response>
   S:</epp>

   The status of the NV object after returning this response MUST
   include "pendingCompliant".  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 outcome
   of the review.

   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 <nv:panData>
   element that identifies the NV namespace.  The <nv:panData> element
   contains the following child elements:

      A <nv:code> element that contains the id of the verification code
      with the required "type" attribute that defines the type of the
      verification code.

      A <nv:paStatus> element that contains the current status
      descriptors associated with the NV.

      A <nv:msg> element containing a human-readable description of the
      result.  The language of the response is identified via an
      OPTIONAL "lang" attribute.  If not specified, the default
      attribute value MUST be "en" (English).

      A <nv:paDate> element that contains the date and time describing
      when review of the requested action was completed.

5.  Formal Syntax

   An EPP object NV 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.

      BEGIN
   <?xml version="1.0" encoding="UTF-8"?>

   <schema targetNamespace="urn:ietf:params:xml:ns:nv-1.0"
     xmlns:nv="urn:ietf:params:xml:ns:nv-1.0"
     xmlns:epp="urn:ietf:params:xml:ns:epp-1.0"
     xmlns:eppcom="urn:ietf:params:xml:ns:eppcom-1.0"
     xmlns:verificationCode=
       "urn:ietf:params:xml:ns:verificationCode-1.0"
     xmlns="http://www.w3.org/2001/XMLSchema"

6.  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.  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, the elements, 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 is
   requested to assignment the following two URI.

   Registration request for the NV namespace:

   o  URI: urn:ietf:params:xml:ns:nv-1.0

Internet-Draft               EPP NV Mapping                     May 2016


   o  Registrant Contact: See the "Author's Address" section of this
      document.

   o  XML: None.  Namespace URI does not represent an XML specification.

   Registration request for the NV XML schema:

   o  URI: urn:ietf:params:xml:schema:nv-1.0

   o  Registrant Contact: See the "Author's Address" section of this
      document.

   o  XML: See the "Formal Syntax" section of this document.

7.2.  EPP Extension Registry

   The EPP extension described in this document should be registered by
   the IANA in the EPP Extension Registry described in [RFC7451].  The
   details of the registration are as follows:

   Name of Extension: Extensible Provisioning Protocol (EPP) China Name
   Verification Mapping

   Document status: Informational

   Reference: (insert reference to RFC version of this document)

   Registrant Name and Email Address: IESG, <iesg@ietf.org>

   TLDs: Any

   IPR Disclosure: None

   Status: Active

   Notes: None

8.  Security considerations

   Verification Code Tokens are digitally signed using XML Signature
   technology.  The security considerations described in Section 12 of
   the W3C XML Signature Syntax and Processing Candidate Recommendation
   [W3C.CR-xmldsig-core2-20120124] apply to this specification as well.
   The object mapping described in this document does not provide any
   other security services or introduce any additional considerations
   beyond those described by [RFC5730] or those caused by the protocol
   layers used by EPP.

10.  Change History

   RFC Editor: Please remove this section.

10.1.  draft-xie-eppext-nv-mapping-00: Version 00

   o  First draft.

10.2.  Change from 00 to 01

   1.  Made the <nv:code> element of the panDataType and pendingType
       require the "type" attribute in the XML schema.

   2.  Fixed the XML schema to include the <nv:rnvCode> OPTIONAL
       element.

   3.  Added the support for the OPTIONAL "lang" attribute for the
       <nv:msg> element of the <nv:failed> and <nv:panData> elements.

10.3.  Change from 01 to 02

   o  Ping update.
