    Registrar Registration Expiration Date Extension Mapping for the
                 Extensible Provisioning Protocol (EPP)
         draft-lozano-ietf-regext-registrar-expiration-date-00

Abstract

   This document describes an Extensible Provisioning Protocol (EPP)
   extension mapping for the provisioning and management of the
   registrar registration expiration date for domain names stored in a
   shared central repository.  Specified in XML, this mapping extends
   the EPP domain name mapping.

1.  Introduction

   This document describes an extension mapping for version 1.0 of the
   Extensible Provisioning Protocol (EPP) described in RFC [RFC5730].
   This mapping, an extension of the domain name mapping described in
   RFC [RFC5731], is specified using the Extensible Markup Language
   (XML) 1.0 [W3C.REC-xml] and XML Schema notation
   ([W3C.REC-xmlschema-1] [W3C.REC-xmlschema-2]).

   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.

   This document is written following the Guidelines for Extending the
   Extensible Provisioning Protocol as defined in [RFC3735].

   This extension is defined in order to support the Internet
   Corporation for Assigned Names and Numbers (ICANN) Thick Whois Policy
   Recommendation [ThickWhoisPolicy] that allows gTLD domain name
   registries to display the registrar registration expiration date in
   the Registration Data Directory Service (e.g.  Whois, RDAP).

1.1.  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 RFC 2119 [RFC2119].

   In examples, "C:" represents lines sent by a protocol client, and
   "S:" represents lines returned by a protocol server. "////" is used
   to note element values that have been shortened to better fit page
   boundaries.  Indentation and white space in examples is provided only
   to illustrate element relationships and is not a mandatory feature of
   this protocol.

   XML is case sensitive.  Unless stated otherwise, XML specifications
   and examples provided in this document MUST be interpreted in the
   character case presented in order to develop a conforming
   implementation.

   rrExDate-1.0 is used as an abbreviation for
   urn:ietf:params:xml:ns:rrExDate-1.0.  The XML namespace prefix
   "rrExDate" 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.

2.  Object Elements

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

2.1.  Synchronize Registry and Registrar Expiration Date

   A <rrExDate:syncRyRrExpDate> element MUST contain a "flag" attribute.
   The "flag" attribute contains an XML Schema boolean value.

      A value of "true" or "1" (one) indicates that the registrar
      registration expiration date shall have the same value as the
      registry expiration date of the domain object (<domain:exDate>) at
      all times.

      A value of "false" or "0" (zero) indicates that the registrar
      registration expiration date is defined in <rrExDate:exDate>.

      A value of "false" or "0" (zero) without an <rrExDate:exDate>
      element indicates that the registrar registration expiration date
      is not defined, or shall be removed, as the case may be.

Internet-Draft   Registrar Registration Expiration Date     October 2016


2.2.  Registrar Registration Expiration Date

   An OPTIONAL <rrExDate:exDate> element is used by the registrar to
   specify the value of the registrar registration expiration date.  The
   <rrExDate:exDate> element MUST NOT be included, if the "flag"
   attribute in <rrExDate:syncRyRrExpDate> is set to "true" or "1"
   (one).

3.  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 of the registrar registration expiration date via EPP.

3.1.  EPP Query commands

   EPP provides three commands to retrieve object information: <check>
   to 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.

3.1.1.  EPP <check> command

   This extension does not add any elements to the EPP <check> command
   or <check> response described in the EPP domain mapping [RFC5731].

3.1.2.  EPP <info> command

   This extension does not add any elements to the EPP <info> command,
   but does include elements in the response.

   After an info command has been processed successfully, the server
   MUST include a <rrExDate:rrExDateData> object in the <extension>
   section of the EPP response.

   Example <info> response for a domain object:

3.1.3.  EPP <transfer> command

   This extension does not add any elements to the EPP <transfer>
   command or <transfer> response described in the EPP domain mapping
   [RFC5731].

3.2.  EPP Transform commands

   The following general requirements apply to the <create>, <renew>,
   <transfer>, and <update> commands:

      A server MUST return a 2004 response code when receiving an EPP
      transform command that includes this extension with a value in the
      <rrExDate:exDate> element that precedes the creation date of the
      domain object (<domain:crDate>).

      A server MUST return a 2002 response code when receiving an EPP
      transform command that includes this extension with a
      <rrExDate:exDate> element, and a value of "true" or "1" (one) in
      the "flag" attribute in the <rrExDate:syncRyRrExpDate> element.

3.2.1.  EPP <create> command

   This extension defines additional elements for the EPP <create>
   command.  The general requirements for EPP transform commands
   described above apply to the EPP <create> command.

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.

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 rrExDate namespace:

      URI: urn:ietf:params:xml:ns:rrExDate-1.0"

      Registrant Contact: IESG

      XML: None.  Namespace URIs do not represent an XML specification.

   Registration request for the rrExDate schema:

      URI: urn:ietf:params:xml:schema:rrExDate-1.0"

      Registrant Contact: IESG

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

7.  Internationalization Considerations

   The internationalization considerations of EPP described in [RFC5730]
   apply to this specification as well.

8.  Security Considerations

   The mapping extensions described in this document do not provide any
   security services beyond those described by EPP [RFC5730], the EPP
   domain name mapping [RFC5731], and protocol layers used by EPP.  The
   security considerations described in these other specifications apply
   to this specification as well.
