       Reseller Extension for the Extensible Provisioning Protocol (EPP)
                       draft-ietf-regext-reseller-ext-01

    Abstract

       This mapping, an extension to EPP object mappings like the EPP domain
       name mapping [RFC5731], to support assigning a reseller to any
       existing object (domain, host, contact) as well as any future
       objects.  Specified in Extensible Markup Language (XML), this
       extended mapping is applied to provide additional features required
       for the provisioning of resellers.

    Internet-Draft       Reseller Extension for the EPP        December 2016

    1.  Introduction

       Domain resellers are the individuals or companies act as agents for
       ICANN accredited registrars.  A domain name registrar may have
       several resellers to help them sell domain names to end users.

       Generally speaking, resellers provide domain registration information
       via registrar's EPP client without reseller information.  On one
       hand, registrars are concerned about how to identify resellers.  On
       the other hand, end users would also be confused by the WHOIS service
       without corresponding reseller information.  This requirement imposes
       a challenge for the domain registries since there is no definition of
       resellers in the existing EPP domain name mapping.  Out of band
       method could solve this problem but may increase extra cost.

       In order to facilitate provisioning and management of reseller
       information in a shared central repository, this document proposes a
       reseller extension of [RFC5731], [RFC5732] and [RFC5733].  The
       examples provided in this document are used for the domain object for
       illustration purposes.  The host and contact object could be extended
       in the same way with the domain object.

       A reseller mapping object defined in [ID.draft-ietf-regext-reseller]
       SHOULD be created first.  The reseller information specified in this
       document SHOULD reference the existing reseller identifier and
       reseller name.

       This document is specified using the 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].

    2.  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 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.

       resellerext-1.0 in this document is used as an abbreviation for
       urn:ietf:params:xml:ns:resellerext-1.0.

    Internet-Draft       Reseller Extension for the EPP        December 2016

    3.  Object Attributes

       This extension adds additional elements to the EPP domain name
       mapping [RFC5731].  Only the new elements are described here.

    3.1.  Reseller Identifier

       Reseller identifier provides the ID of the reseller of a sponsoring
       registrar.  Its corresponding element is <resellerext:id> which
       refers to the <reseller:id> element defined in
       [ID.draft-ietf-regext-reseller].  All reseller objects are identified
       by a server-unique identifier

    3.2.  Reseller Name

       Reseller name provides the name of the reseller of a sponsoring
       registrar.  Its corresponding element is <resellerext:name> which
       refers to the <reseller:name> element defined in
       [ID.draft-ietf-regext-reseller].

    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 reseller information via EPP.

    4.1.  EPP Query Commands

       EPP provides three commands to retrieve domain information: <check>
       to determine if a domain object can be provisioned within a
       repository, <info> to retrieve detailed information associated with a
       domain object, and <transfer> to retrieve domain-object transfer
       status information.

    4.1.1.  EPP <check> Command

       This extension does not add any elements to the EPP <check> command
       or <check> response described in the EPP domain name mapping
       [RFC5731], host mapping [RFC5732] and contact mapping [RFC5733].

    4.1.2.  EPP <info> Command

       This extension does not add any element to the EPP <info> command
       described in the EPP domain mapping [RFC5731], host mapping [RFC5732]
       and contact mapping [RFC5733].  However, additional elements are
       defined for the <info> response.

    Zhou, et al.              Expires June 10, 2017                 [Page 4]

    Internet-Draft       Reseller Extension for the EPP        December 2016

       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:      <domain:info xmlns:domain="urn:ietf:params:xml:ns:domain-1.0">
      C:        <domain:name>example.com</domain:name>
      C:        <domain:authInfo>
      C:          <domain:pw>fooBAR</domain:pw>
      C:        </domain:authInfo>
      C:      </domain:info>
      C:    </info>
      C:    <clTRID>ngcl-mIFICBNP</clTRID>
      C:  </command>
      C:</epp>

       When an <info> command has been processed successfully, the EPP
       <resData> element MUST contain child elements as described in the EPP
       domain mapping [RFC5731], host mapping [RFC5732] and contact mapping
       [RFC5733].  In addition, the EPP <extension> element SHOULD contain a
       child <resellerext:infData> element that identifies the extension
       namespace if the domain object has data associated with this
       extension and based on its service policy.  The <resellerext:infData>
       element contains the following child elements:

       o  A <resellerext:id> element that contains the identifier of the
          reseller of a sponsoring registrar.

       Example <info> response for an authorized client:

       <info> response for the unauthorized client has not been changed, see
       [RFC5731], [RFC5732] and [RFC5733]for detail.

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

    Internet-Draft       Reseller Extension for the EPP        December 2016

    4.1.3.  EPP <transfer> Command

       This extension does not add any elements to the EPP <transfer>
       command or <transfer> response described in the EPP domain name
       mapping [RFC5731], host mapping [RFC5732] and contact mapping
       [RFC5733].

    4.2.  EPP Transform Commands

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

    4.2.1.  EPP <create> Command

       This extension defines additional elements for the EPP <create>
       command described in the EPP domain mapping [RFC5731], host mapping
       [RFC5732] and contact mapping [RFC5733].  No additional elements are
       defined for the EPP <create> response.

       The EPP <create> command provides a transform operation that allows a
       client to create a domain object.  In addition to the EPP command
       elements described in the EPP domain mapping [RFC5731], host mapping
       [RFC5732] and contact mapping [RFC5733], the command MUST contain an
       <extension> element, and the <extension> element MUST contain a child
       <resellerext:create> element that identifies the extension namespace
       if the client wants to associate data defined in this extension to
       the domain object.  The <resellerext:create> element contains the
       following child elements:

       o  A <resellerext:id> element that contains the identifier of the
          reseller of a sponsoring registrar.

       Example <create> Command:

    C:  </command>
    C:</epp>

       When a <create> command has been processed successfully, the EPP
       response is as described in the EPP domain mapping [RFC5731], host
       mapping [RFC5732] and contact mapping [RFC5733].

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

    4.2.2.  EPP <delete> Command

       This extension does not add any elements to the EPP <delete> command
       or <delete> response described in the EPP domain mapping [RFC5731],
       host mapping [RFC5732] and contact mapping [RFC5733].

       command or <transfer> response described in the EPP domain mapping
       [RFC5731], host mapping [RFC5732] and contact mapping [RFC5733], but
       after a successful transfer of an object with an assigned reseller,
       the server SHOULD clear the assigned reseller value.

    4.2.5.  EPP <update> Command

       This extension defines additional elements for the EPP <update>
       command described in the EPP domain mapping [RFC5731], host mapping
       [RFC5732] and contact mapping [RFC5733].  No additional elements are
       defined for the EPP <update> response.

       The EPP <update> command provides a transform operation that allows a
       client to modify the attributes of a domain object.  In addition to
       the EPP command elements described in the EPP domain mapping, the
       command MUST contain an <extension> element, and the <extension>
       element MUST contain a child <resellerext:update> element that
       identifies the extension namespace if the client wants to update the
       domain object with data defined in this extension.  The
       <resellerext:update> element contains the following child elements:

       o  An OPTIONAL <resellerext:add> element that contains attribute
          values to be added to the object.

       o  An OPTIONAL <resellerext:rem> element that contains attribute
          values to be removed from the object.

       o  An OPTIONAL <resellerext:chg> element that contains attribute
          values to be changed.

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

       o  A <resellerext:id> element that contains the identifier of the
          reseller of a sponsoring registrar.

       Example <update> command, adding a reseller:

    C:</epp>

       When an extended <update> command has been processed successfully,
       the EPP response is as described in the EPP domain name mapping
       [RFC5731], host mapping [RFC5732] and contact mapping [RFC5733].

    5.  Formal Syntax

       An EPP object mapping is specified in XML Schema notation.  The
       formal syntax presented here is a complete schema representation of
       the object mapping suitable for automated validation of EPP XML
       instances.  The BEGIN and END tags are not part of the schema; they
       are used to note the beginning and ending of the schema for URI
       registration purposes.

    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 domain name mapping, 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 URI.

       Registration request for the reseller namespace:

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

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

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

    Internet-Draft       Reseller Extension for the EPP        December 2016

    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: Domain Reseller Extension

       Document status: Standards Track

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

       Registrant Name and Email Address: See the "Author's Address" section
       of this document.

       TLDs: any

       IPR Disclosure: none

       Status: active

       Notes: none

    8.  Security Considerations

       The object mapping extension described in this document does not
       provide any other security services or introduce any additional
       considerations beyond those described by [RFC5730], [RFC5731],
       [RFC5732] and [RFC5733] or those caused by the protocol layers used
       by EPP.

       The authors would like to thank Rik Ribbers, Marc Groeneweg and
       Patrick Mevzek for their careful review and valuable comments.

          *  Revised the typo "resellerr" to "resellerext".

       WG document-00:  WG document submitted

       WG document-01:  Keep document alive for further discussion.  The
          requirement of reseller information is clear for both registrar
          and registry.  What we should reach a consensus is whether the
          extension should support only a name or ID and name.
