Table of Contents

1. Introduction

This document describes an extension mapping for version 1.0 of the Extensible Provisioning Protocol (EPP) [RFC5730]. This document describes a Domain Name Registry Mapping, referred to as Registry Mapping, for the Extensible Provisioning Protocol (EPP) [RFC5730]. A Domain Name Registry can service one or more zones (e.g. top-level domains) with a variety of supported services and policies. This mapping enables the provisioning of the zones in the Domain Name Registry. A Domain Name Registry MAY support a subset of all of the commands defined in this mapping.

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.

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

An EPP registry object has attributes and associated values that may 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. Zone Name

The syntax for zone names described in this document MUST conform to [RFC0952] and [RFC1123]. At the time of this writing, [RFC3490] describes a standard to use certain ASCII name labels to represent non-ASCII name labels. These conformance requirements might change in the future as a result of progressing work in developing standards for internationalized names.

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.

2.3. Zone Object

The Zone object, represented by the <registry:zone> element, is the primary object managed by this mapping. The Zone object can apply to any zone level (top level, second level, third level, etc.). The <registry:zone> element contains the following child elements:

<registry:name>
The zone name that can be at any level (top level, second level, third level, etc.).
<registry:group>
An OPTIONAL server defined grouping of zones where the zones belong to the same deployable unit.
<registry:subProduct>
An OPTIONAL sub-product identifier used for the zone and used as the value of the <namestoreExt:subProduct> element of the NameStore EPP Extension.
<registry:related>
An OPTIONAL definition of the related zones, where there MAY be different forms of relationships. The <registry:related> element contains the following child elements:
<registry:fields>
An OPTIONAL definition of how related zone fields are managed. The <registry:fields> element includes a required "type" attribute with either a "shared" or "sync" value. A "shared" value indicates that the server shares a single set of field values across the related zones, where updating a field in one related zone results in updating the field value across all of the related zones. A "sync" value indicates that the field values MUST be synchronized across the related zones by server policy. The <registry:fields> element contains the following child elements:
<registry:field>
One or more <registry:field> elements that are shared or MUST be synchronized according to the <registry:fields> "type" attribute value. An example field value is "clID" to refer to the identifier of the sponsoring client or "registrant" to refer to the registrant contact.
<registry:zoneMember>
One or more <registry:zoneMember> elements that defines the related zones. The value of the <registry:zoneMember> element is the zone name. The <registry:zoneMember> element includes a required "type" attribute with one of the following values:
"primary"
All domain names in the zone MUST be a primary domain name. A primary domain name MUST be the first one created and the last one deleted in the set of related domain names.
"alternate"
Domain names of the zone can only be created when the primary domain name exists.
"primaryBasedOnCrDate"
A domain name in the zone can be either a primary or alternate domain name based on the earliest created date. The first domain name created in the related zones will become the primary domain name and alternate domain names can be created / deleted.
"equal"
There is no concept of primary and alternate domain names, so the related zones are treated as equal. Domain names can be created and deleted in any order.
<registry:phase>
Zero or more <registry:phase> elements that defines a phase of the zone based on the phases defined in the Launch Phase Mapping for the Extensible Provisioning Protocol (EPP). The "type" attribute defines the phase name / type that include the following possible values with an OPTIONAL "name" attribute that defines the name of the type when the "type" attribute is set to "custom" or the name of the sub-type of the "type". The "mode" attribute reflects the mode in which the phase runs. The <registry:phase> element contains a <registry:startDate> child element that defines the start date and time of the phase and an OPTIONAL <registry:endDate> child element that defines the end date and time of the phase. The "type" attribute supports the following values:

"sunrise"
Phase when trademark holders can submit registration applications with trademark information that can be validated by the server.
"landrush"
Post sunrise phase when non-trademark holders are allowed to register domain names.
"claims"
Trademark claims phase as defined by Trademark Clearinghouse model of displaying a claims notice to clients for domain names that match trademarks.
"open"
Post launch phase that is also referred to as "steady state". Servers MAY require additional trademark protection with this phase.
"custom"
A custom server launch phase that is defined using the "name" attribute.
The "mode" attribute supports the following values with the default value of "fcfs":
"fcfs"
first-come-first-serve. In this mode, each domain name is immediately created and there is no use of an application identifier.
"pending-registration"
In this mode, the domain name is created with the pendingCreate status with no use of an application identifier.
"pending-application"
In this mode, the domain name, referred to as a domain application, is created in pendingCreate status with the server returning an application identifier in the create response for the client to use in subsequent commands (info, update, delete). When a domain application is allocated, it will become a domain without the use of an application identifier.

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 TLD names via EPP.

3.1. EPP Query Commands

EPP [RFC5730] 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

The EPP <check> command is used to determine if the server currently supports a zone. If the response indicates that the zone is not available, then it is currently supported; otherwise it MAY be available to be created by an authorized client.

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

<registry:name>
One or more <registry:name> elements that contain the fully qualified names of the zone 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:  <command>
C:    <check>
C:      <registry:check
C:       xmlns:registry="http://www.verisign.com/epp/registry-1.0">
C:        <registry:name>zone1</registry:name>
C:        <registry:name>zone2</registry:name>
C:        <registry:name>zone3</registry:name>
C:      </registry: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 <registry:chkData> element that identifies the registry namespace. The <registry:chkData> element contains one or more <registry:cd> elements that contain the following child elements:

<registry:name>
element that contains the fully qualified name of the queried zone object. This element MUST contain an "avail" attribute whose value indicates zone is currently supported or availability at the moment the <check> command was completed for an authorized client. A value of "1" or "true" means that the zone object is available for an authorized client. A value of "0" or "false" means that the zone object is currently supported by the server.
<registry:reason>
The OPTIONAL element that MAY be provided when a zone object is not available for provisioning. If present, this element contains server-specific text to help explain why the zone object is unavailable. 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 a 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:      <registry:chkData
S:        xmlns:registry=
S:        "http://www.verisign.com/epp/registry-1.0">
S:        <registry:cd>
S:          <registry:name avail="0">zone1</registry:name>
S:          <registry:reason>Client not authorized
S:          </registry:reason>
S:        </registry:cd>
S:        <registry:cd>
S:          <registry:name avail="0">zone2
S:          </registry:name>
S:          <registry:reason>Already supported
S:          </registry:reason>
S:        </registry:cd>
S:        <registry:cd>
S:          <registry:name avail="1">zone3
S:          </registry:name>
S:        </registry:cd>
S:      </ registry: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.

3.1.2. EPP <info> Command

The EPP <info> command is used to retrieve information associated with a zone object. The response to this command MAY vary depending on the identity of the querying client, use of authorization information, and server policy towards unauthorized clients. Server policy determines which OPTIONAL elements are returned.

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

<registry:all>
element that is empty and that indicates that a list of all of the supported zone objects are queried with a summary set of attributes per zone object.
or a <registry:name>
element that contains the fully qualified name of the zone object to be queried for a full set of attributes for the zone object.

Example <info> command to query for a summary set of attributes for all of the supported zone objects:

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:      <registry:info
C:        xmlns:registry="http://www.verisign.com/epp/registry-1.0">
C:        <registry:all/>
C:      </registry:info>
C:    </info>
C:    <clTRID>ABC-12345</clTRID>
C:  </command>
C:</epp>

Example <info> command to query for the full set of "zone1" zone object attributes:

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:      <registry:info
C:        xmlns:registry="http://www.verisign.com/epp/registry-1.0">
C:        <registry:name>zone1</registry:name>
C:      </registry:info>
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 <registry:infData> element that identifies the registry namespace. The <registry:infData> element contains one of the two following child elements:

<registry:zoneList>
element that contains the list of supported zones by the server with a set of summary attributes per zone. The <registry:zoneList> element contains the following child elements:
<registry:name>
element that contains the fully qualified name of the queried zone object.
<registry:crDate>
The date and time of zone object creation.
<registry:upDate>
The OPTIONAL date and time of the most recent zone object modification.
or a <registry:zone>
element that contains the full set of attributes for the zone name as defined in Section 2.3.

Example <info> response to a query for a summary of all of the supported zone objects:

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:    </result>
S:    <resData>
S:      <registry:infData
S:        xmlns:registry="http://www.verisign.com/epp/registry-1.0">
S:        <registry:zoneList>
S:          <registry:zone>
S:            <registry:name>EXAMPLE1</registry:name>
S:            <registry:crDate>2012-10-01T00:00:00.0Z
S:            </registry:crDate>
S:            <registry:upDate>2012-10-15T00:00:00.0Z
S:            </registry:upDate>
S:          </registry:zone>
S:          <registry:zone>
S:            <registry:name>EXAMPLE2</registry:name>
S:            <registry:crDate>2012-09-01T00:00:00.0Z
S:            </registry:crDate>
S:            <registry:upDate>2012-09-19T00:00:00.0Z
S:            </registry:upDate>

S:      <clTRID>ABC-12345</clTRID>
S:      <svTRID>54322-XYZ</svTRID>
S:    </trID>
S:  </response>
S:</epp>

Example <info> response to query for the full set of "EXAMPLE" zone object attributes:

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:    </result>
S:    <resData>
S:      <registry:infData
S:        xmlns:registry="http://www.verisign.com/epp/registry-1.0">
S:        <registry:zone>
S:          <registry:name>EXAMPLE</registry:name>
S:          ...
S:        </registry:zone>
S:      </registry:infData>
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 an <info> command cannot be processed for any reason.

3.1.3. EPP <transfer> Command

Transfer semantics do not directly apply to zone objects, so there is no mapping defined for the EPP <transfer> query command.

3.2. EPP Transform Commands

EPP provides five commands to transform 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.

3.2.1. EPP <create> Command

The EPP <create> command provides a transform operation that allows a client to create a zone object. In addition to the standard EPP command elements, the <create> command MUST contain a <registry:create> element that identifies the registry namespace. The <registry:create> element contains the following child elements:

<registry:zone>
element that contains the full set of attributes for the zone to create as defined in Section 2.3.

Example <create> 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:  <command>
C:    <create>
C:      <registry:create
C:        xmlns:registry="http://www.verisign.com/epp/registry-1.0">
C:        <registry:zone>
C:          <registry:name>EXAMPLE</registry:name>
C:          ...
C:        </registry:zone>
C:      </registry:create>
C:    </create>
C:    <clTRID>ABC-12345</clTRID>
C:  </command>
C:</epp>

When a <create> command has been processed successfully, the EPP <resData> element MUST contain a child <registry:creData> element that identifies the registry namespace. The <registry:creData> element contains the following child elements:

<registry:name>
element that contains the fully qualified name of the zone object.
<registry:crDate>
element that contains the date and time of zone object creation.

Example <create> 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:    </trID>
S:  </response>
S:</epp>

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

3.2.2. EPP <delete> Command

The EPP <delete> command provides a transform operation that allows a client to delete a zone object. In addition to the standard EPP command elements, the <delete> command MUST contain a <registry:delete> element that identifies the registry namespace. The <registry:delete> element contains the following child elements:

<registry:name>
element that contains the fully qualified name of the zone object to be deleted.

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:  <command>
C:    <delete>
C:      <registry:delete
C:        xmlns: registry="http://www.verisign.com/epp/registry-1.0">
C:        <registry:name>EXAMPLE</registry:name>
C:      </registry:delete>
C:    </delete>
C:    <clTRID>ABC-12345</clTRID>
C:  </command>
C:</epp>

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

Example <delete> 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:      <clTRID>ABC-12345</clTRID>
S:      <svTRID>54321-XYZ</svTRID>
S:    </trID>
S:  </response>
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

Renew semantics do not directly apply to zone objects, so there is no mapping defined for the EPP <renew> command.

3.2.4. EPP <transfer> Command

Transfer semantics do not directly apply to zone objects, so there is no mapping defined for the EPP <transfer> command.

3.2.5. EPP <update> Command

The EPP <update> command provides a transform operation that allows a client to modify the attributes of a zone object. In addition to the standard EPP command elements, the <update> command MUST contain a <registry:update> element that identifies the registry namespace. The <registry:update> element contains the following child elements:

<registry:zone>
One or more elements that contain the full set of attributes for the zones as defined in Section 2.3. The update completely replaces the prior version of the zone.

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:      <registry:update
C:        xmlns:registry="http://www.verisign.com/epp/registry-1.0">
C:        <registry:zone>
C:          <registry:name>EXAMPLE</registry:name>
C:          ...
C:        </registry:zone>
C:      </registry:update>
C:    </create>
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> 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="1000">
S:      <msg>Command completed successfully</msg>
S:    </result>
S:    <trID>
S:      <clTRID>ABC-12345</clTRID>
S:      <svTRID>54321-XYZ</svTRID>
S:    </trID>
S:  </response>
S:</epp>

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

4. Formal Syntax

One schema is presented here that is the EPP Registry 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.
