1. Introduction
Bundled domain names are those sharing the same TLD but whose second
level labels are variants, or those that have identical second level
labels for which certain parameters are shared in the different TLDs.
For example, Public Interest Registry requested to implement
technical bundling of second level domains for .NGO and .ONG
Kong, et al. Expires April 30, 2015 [Page 2]
Internet-Draft EPP bundled names Mapping October 2014
[bundling]. So we have two kinds of bundled domain names. First one
is in the form of "V-label.TLD" in which the second level labels
(V-label) are variants sharing the same TLD; Second one is in the
form of "LABEL.V-tld" in which the second level labels are the same
but belong to different TLDs (V-tld).
For the name variants, some registries adopt the policy that variant
IDNs which are identified as equivalent are allocated or delegated to
the same registrant. For example, the specified registration policy
of Chinese Domain Name (CDN) is that a registrant can apply an
original CDN in any forms: Simplified Chinese (SC) form, Traditional
Chinese (TC) form, or other variant forms, then the corresponding
variant CDN in SC form and that in TC form will also be delegated to
the same registrant. All variant names in the same TLD share the
same attributes.
The basic Extensible Provisioning Protocol (EPP) domain name mapping
[RFC5731] provides the domain name registration one by one. It does
not specify how to register the bundled domain names which share the
same attributes.
In order to meet above requirements of bundling registration of
domain names, this document describes an extension of the EPP domain
name mapping [RFC5731] for the provisioning and management of bundled
names. 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 extension of mapping described in this document.
This document uses lots of the concepts of the IDN, so a thorough
understanding of the IDNs for Application (IDNA, described in
[RFC5890], [RFC5891], and [RFC5892]) and a thorough understanding of
variant approach discussed in [RFC4290] are both required.
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].
"b-dn-1.0" in this document is used as an abbreviation for
urn:ietf:params:xml:ns:b-dn-1.0.

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
The following definitions are used in this document:
o Registered Domain Name (RDN), represents the valid domain name
that users submitted for registration for the first time.
o Bundled Domain Name (BDN), represents the bundled domain name
produced according to the bundled domain name registration policy.
4. Overview
Domain registries have traditionally adopted a registration model
whereby metadata relating to a domain name, such as its expiration
date and sponsoring registrar, are stored as properties of the domain
object. The domain object is then considered an atomic unit of
registration, on which operations such as update, renewal and
deletion may be performed.
Bundled names brought about the need for multiple domain names to be
registered and managed as a single package. In this model, the
registry typically accepts one domain registration request (i.e. EPP
domain <create> command) containing the domain name to be registered.
This domain name is referred to as the RDN in this document. As part
of the processing of the registration request, the registry generates
a set of bundled names that are related to the RDN, either
programmatically or with the guidance of registration policies, and
place them in the registration package together with the RDN.
The bundled names SHOULD have the same properties, such as expiration
date and sponsoring registrar, by sharing one domain object. So when
users update any properties within a bundle package, all of the
domains' properties within the bundle package SHOULD be updated.
5. Requirement for Bundling Registration of Domain Names
The bundled names either in the form of "V-label.TLD" or in the form
of "LABEL.V-tld" SHOULD share the following parameters or attributes:
o Registrar Ownership
Kong, et al. Expires April 30, 2015 [Page 4]
Internet-Draft EPP bundled names Mapping October 2014
o Registration and Expiry Dates
o Registrant, Admin, Billing, and Technical Contacts
o Name Server Association
o Domain Status
o Applicable grace periods (Add Grace Period, Renewal Grace Period,
Auto-Renewal Grace Period, Transfer Grace Period, and Redemption
Grace Period)
Because the domain names within one bundle package are bundled and
share the same parameters or attributes, the EPP command should
support the following processings for these requirements:
o When performing a domain check, either BDN or RDN can be queried
for the EPP command, and will return the same response.
o When performing a domain Create, either BDN or RDN will be
accepted. If the domain name is available, both BDN and RDN will be
registered.
o When performing a domain update, either BDN or RDN will be
accepted. Any modifications to contact associations, name server
associations, domain status values and authorization information will
be applied to both BDN and RDN.
o When performing a domain query, either BDN or RDN will be accepted.
If the domain name is available, the information returned by the
command will be compliant with the core EPP RFCs.
o When performing a domain renew, either BDN or RDN will be accepted.
Upon a successful domain renewal, both BDN and RDN will have their
expiry date extended by the requested term. Upon a successful domain
renewal, both BDN and RDN will conform to the same renew grace
period.
o When performing a domain transfer, either BDN or RDN will be
accepted. Upon successful completion of a domain transfer request,
both BDN and RDN will enter a pendingTransfer status. Upon approval
of the transfer request, both BDN and RDN will be owned and managed
by the same new registrant.
6. Object Attributes
This extension defines following additional elements to the EPP
domain name mapping [RFC5731]. All of these additional elements can
be got from <domain:info> command.
6.1. RDN
The RDN is an ASCII name or an IDN with the A-label [RFC5890] form
which is converted from the corresponding RDN. In this document, its
corresponding element is <b-dn:rdn>. An attribute "uLabel"
associated with <b-dn:rdn> is used to represent the U-label [RFC5890]
form. An optional boolean "activated" attribute, with a default true
Kong, et al. Expires April 30, 2015 [Page 5]
Internet-Draft EPP bundled names Mapping October 2014
value, is used to indicate the presence of the label in the zone
file.
For example: <b-dn:rdn uLabel="U+5B9E""U+4F8B".example> xn--
fsq270a.example</b-dn:rdn>
6.2. BDN
The BDN is an ASCII name or an IDN with the A-label [RFC5890] form
which is converted from the corresponding BDN. In this document, its
corresponding element is <b-dn:bdn>. An attribute "uLabel"
associated with <b-dn:bdn> is used to represent the U-label [RFC5890]
form. An optional boolean "activated" attribute, with a default true
value, is used to indicate the presence of the label in the zone
file.
For example: <b-dn:bdn uLabel="U+5BE6""U+4F8B".example> xn--
fsqz41a.example</b-dn:bdn>
7. 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 bundled names via EPP.
7.1. 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.
7.1.1. EPP <check> Command
This extension does not add any element to the EPP <check> command or
<check> response described in the EPP domain name mapping [RFC5731].
When a domain name has not been registered, but the domain which the
user submitted for check is a registered domain name's BDN, <check>
response SHOULD contain explanation in the reason field to tell the
user that this domain name is a produced name according to some
bundle domain name policy.
Kong, et al. Expires April 30, 2015 [Page 6]
Internet-Draft EPP bundled names Mapping October 2014
7.1.2. EPP <info> Command
This extension does not add any element to the EPP <info> command
described in the EPP domain mapping [RFC5731]. However, additional
elements are defined for the <info> response.
When an <info> command has been processed successfully, the EPP
<resData> element MUST contain child elements as described in the EPP
domain mapping [RFC5731]. In addition, the EPP <extension> element
SHOULD contain a child <b-dn:infData> element that identifies the
extension namespace if the domain object has data associated with
this extension and based on its service policy. The <b-dn:infData>
element contains the <b-dn:bundle> which has the following child
elements:
o An <b-dn:rdn> element that contains the RDN, along with the
attributes described below.
o An OPTIONAL <b-dn:bdn> element that contains the BDN, along with
the attributes described below.
The above elements contain the following attributes:
o An optional "uLabel" attribute represents the U-label of the
element.
o An optional "activated" attribute that defaults to true,
indicating the presence of the variant in the zone file.

<info> Response for the unauthorized client has not been changed, see
[RFC5731] for detail.
An EPP error response MUST be returned if an <info> command cannot be
processed for any reason.
7.1.3. EPP <transfer> Query Command
This extension does not add any element to the EPP <transfer> command
or <transfer> reponse described in the EPP domain mapping [RFC5731].
7.2. 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.
7.2.1. EPP <create> Command
This extension defines additional elements to extend the EPP <create>
command described in the EPP domain name mapping [RFC5731] for
bundled names registration.
In addition to the EPP command elements described in the EPP domain
mapping [RFC5731], the <create> command SHALL contain an <extension>
element. The <extension> element SHOULD contain a child
<b-dn:create> element that identifies the IDN namespace and the
location of the IDN schema.

C:</epp>
When an <create> command has been processed successfully, the EPP
<creData> element MUST contain child elements as described in the EPP
domain mapping [RFC5731]. In addition, the EPP <extension> element
SHOULD contain a child <b-dn:creData> element that identifies the
extension namespace if the domain object has data associated with
this extension and based on its service policy. The <b-dn:creData>
element contains the <b-dn:bundle> which has the following child
elements:
o An <b-dn:rdn> element that contains the RDN, along with the
attributes described below.
o An OPTIONAL <b-dn:bdn> element that contains the BDN, along with
the attributes described below. If the BDN is allowed to be
presented to the registrant by the registration policy, the BDN
SHALL be generated by the server during an <create> command.
After the <create> command has been processed successfully, the
response of the command SHOULD contain an <b-dn:bdn> element.
o Zero or more <b-dn:vidn> elements that contain the VIDNs, along
with the attributes described below.

7.2.2. EPP <delete> Command
This extension does not add any element to the EPP <delete> command
described in the EPP domain mapping [RFC5731]. However, additional
elements are defined for the <delete> response.
When a <delete> command has been processed successfully, the EPP
<delData> element MUST contain child elements as described in the EPP
domain mapping [RFC5731]. In addition, the EPP <extension> element
SHOULD contain a child <b-dn:delData> element that identifies the

this extension and based on its service policy. The <b-dn:delData>
element SHOULD contain the <b-dn:bundle> which has the following
child elements:
o An <b-dn:rdn> element that contains the RDN.

7.2.3. EPP <renew> Command
This extension does not add any element to the EPP <renew> command or
<renew> response described in the EPP domain mapping [RFC5731].
7.2.4. EPP <transfer> Command
This extension does not add any element to the EPP <transfer> command
or <transfer> response described in the EPP domain mapping [RFC5731].
7.2.5. EPP <update> Command
This extension defines additional elements for the EPP <update>
command described in the EPP domain mapping [RFC5731]. 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
[RFC5731], the command SHOULD contain an <extension> element, and the
<extension> element MUST contain a child <b-dn:update> element that
identifies the extension namespace if the client wants to update the
domain object with data defined in this extension. The <b-dn:update>
element SHOULD contain one or more of the following elements:
o An <b-dn:chg> element represents the variant domain name that
could be set as the BDN.
o An <b-dn:add> element with one or more <b-dn:vidn> child elements
that represent VIDNs to be associated with the RDN.
o An <b-dn:activate> element with one or more <b-dn:vidn> child
elements. Each identifies an already existing VIDN to be
activated. A VIDN that is to be associated with the RDN, as
listed in the <b-dn:add> element of the same command, may also be
specified to explicitly signal to the server that the VIDN to be
added should be in an activated state when it is associated.
o An <b-dn:deactivate> element with one or more <b-dn:vidn> child
elements. Each identifies an already existing VIDN to be
deactivated. A VIDN that is to be associated with the RDN, as
listed in the <b-dn:add> element of the same command, may also be
specified to explicitly signal to the server that the VIDN to be
added should be in a deactivated state when it is associated.

[RFC5731].
8. Formal Syntax
An EPP object name mapping extension for bundled names 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.

9. 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.

10. IANA Considerations
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 URIs.
Registration request for the bundled domain names namespace:
o URI: urn:ietf:params:xml:ns:b-dn-1.0
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 bundled domain names XML schema:
o URI: urn:ietf:params:xml:schema:b-dn-1.0
o Registrant Contact: See the "Author's Address" section of this
document.
o XML: See the "Formal Syntax" section of this document.
11. 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] or those caused by
the protocol layers used by EPP.
12. Acknowledgements
The authors especially thank the authors of [RFC5730] and [RFC5731]
and the following ones of CNNIC: Weiping Yang, Chao Qi. This draft
extends the draft draft-kong-epp-idn-variants-mapping to support both
forms of bundled names: V-label.TLD and LABEL.V-tld.
Useful comments were made by John Klensin, Scott Hollenbeck and
Edward Lewis.
