# Table of Contents

# 1. Introduction

This document describes an extension mapping for version 1.0 of the Extensible Provisioning Protocol (EPP) [RFC5730]. This EPP extension supports the poll message created by the server when a restore report has not been submitted for a restore request in the Domain Registry Grace Period (RGP) Mapping [RFC3915].

# 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 RFC 2119 [RFC2119].

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.

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.

"rgp-poll-1.0" is used as an abbreviation for "http://www.verisign.com/epp/rgp-poll-1.0". The XML namespace prefix "rgp-poll" 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 Attributes

The EPP RGP Poll has attributes and associated values that may be viewed by the sponsoring client or server. This section describes each attribute type in detail.

# 2.1. Language Tag

The RGP status attribute includes the non-grace period statuses defined in the Domain Registry Grace Period (RGP) Mapping [RFC3915]. Specifically, the redemptionPeriod, pendingRestore, and pendingDelete statuses MUST be used.

# 2.2. 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 XML Schema Part 2 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.

# 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 mapping described here is specifically for use with the Domain Registry Grace Period (RGP) Mapping [RFC3915].

# 3.1. EPP <poll> Command

The EPP <poll> command and response is defined in section 2.9.2.3 of [RFC5730]. The RGP Poll Notification is included in the EPP <poll> response of [RFC5730].

For the RGP Poll Notification, poll messages apply whenever an [RFC3915] RGP restore request command is successfully completed and the RGP restore report command has not been received. The RGP Poll message includes the domain name, the restore request date, the restore report due date, and the current RGP status of the domain as defined in section 3.1 of [RFC3915]. In the case of a RGP specific message, a <rgp-poll:pollData> element will be included within the <resData> element of the standard <poll> response. The <rgp-poll:pollData> element will include a reference to the rgp-poll namespace. EPP data contained within the <rgp-poll:pollData> element is formatted according to the rgp-poll schema.

Example <poll> 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:  <poll op="req"/>
    C:    <clTRID>ABC-12345</clTRID>
    C:  </command>
    C:</epp>

An RGP Poll Message consists of the <rgp-poll:pollData> element with the following child elements:

<rgp-poll:name>
  The domain name that is a candidate for restoration.
<rgp-poll:rgpStatus>
  The RGP status, using the "s" attribute value of the element, of the domain name as defined in [RFC3915], exclusive of the grace period statuses.
<rgp-poll:reqDate>
  The date and time the server received the restore request.
<rgp-poll:reportDueDate>
  The date and time the restore report MUST be received by the server to restore the domain name.

Example <poll> response with the RGP Poll Message:

    S:<?xml version="1.0" encoding="UTF-8"?>
    S:<epp xmlns="urn:ietf:params:xml:ns:epp-1.0">
    S:  <response>
    S:    <result code="1301">
    S:      <msg>Command completed successfully; ack to dequeue</msg>
    S:    </result>
    S:    <msgQ count="5" id="12345">
    S:      <qDate>2013-05-03T20:06:17.0002Z</qDate>
    S:      <msg>Restore Request Pending</msg>
    S:    </msgQ>
    S:    <resData>
    S:      <rgp-poll:pollData
    S:        xmlns:rgp-poll="http://www.verisign.com/epp/rgp-poll-1.0">
    S:        <rgp-poll:name>foobar.com</rgp-poll:name>
    S:        <rgp-poll:rgpStatus s="pendingDelete"/>
    S:        <rgp-poll:reqDate>2013-05-03T20:06:17.0002Z
    S:        </rgp-poll:reqDate>
    S:        <rgp-poll:reportDueDate>2013-05-08T20:06:17.0002Z
    S:        </rgp-poll:reportDueDate>
    S:      </rgp-poll:pollData>
    S:    </resData>
    S:    <trID>
    S:      <clTRID>ABC-12345</clTRID>
    S:      <svTRID>54322-XYZ</svTRID>
    S:    </trID>
    S:  </response>
    S:</epp>

# 4. Formal Syntax

One schema is presented here that is the RGP Poll Mapping schema.

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.
