Extension Registry for the Extensible Provisioning Protocol
draft-ietf-eppext-reg-05
Abstract
The Extensible Provisioning Protocol (EPP) includes features to add
functionality by extending the protocol. It does not, however,
describe how those extensions are managed. This document describes a
procedure for the registration and management of extensions to EPP
and it specifies a format for an IANA registry to record those
extensions.

2. Introduction
Domain name registries implement a variety of operational and
business models. The differences in these models made it impossible
to develop a "one size fits all" provisioning protocol, so the
Extensible Provisioning Protocol (EPP, [RFC5730]) was designed to
focus on a minimal set of common functionality with built-in
extension capabilities that allow new features to be specified on an
"as needed" basis. Guidelines for extending EPP are documented in
Informational RFC 3735 [RFC3735].
Hollenbeck Expires December 1, 2014 [Page 2]
Internet-Draft EPP Extension Registry May 2014
RFCs 5730 and 5735 do not describe how extension development can be
managed and coordinated. This has led to a situation in which server
operators can develop different extensions to address similar needs,
such as the provisioning of Value Added Tax (VAT) information.
Clients then need to support multiple extensions that serve similar
purposes, and interoperability suffers.
An IANA registry can be used to help manage and coordinate the
development of protocol extensions. This document describes an IANA
registry that can be used to coordinate the development of EPP
extensions.
3. Extension Specification and Registration Procedure
This section describes the format of an IANA registry and the
procedures used to populate and manage registry entries.
3.1. Extension Specification
The "Specification Required" policy described in RFC 5226 [RFC5226]
MUST be followed. Extension specifications MUST be written and
available in the English language. Non-English specifications are
OPTIONAL. Note that Section 2.1 of RFC 3735 [RFC3735] provides
specific guidelines for documenting EPP extensions.
Note that the "Specification Required" policy implies review by a
Designated Expert. Section 3 of RFC 5226 describes the role of
Designated Experts and the function they perform.
3.1.1. Designated Expert Evaluation Criteria
A high-level description of the role of the Designated Expert is
described in Section 3.2 RFC 5226. Specific guidelines for the
appointment of Designated Experts and evaluation of EPP extensions
are provided here.
The IESG should appoint a small pool of individuals (perhaps 3 - 5)
to serve as designated experts as described in Section 3.2 of RFC
5226. The pool should have a single administrative chair who is
appointed by the IESG. The designated experts should use the
existing eppext mailing list (eppext@ietf.org) for public discussion
of registration requests. This implies that the mailing list should
remain open after the work of the EPPEXT working group has concluded.
Extensions should be evaluated for architectural soundness using the
guidelines described in RFC 3735 [RFC3735]. The results of the
evaluation should be shared via email with the registrant and the
eppext mailing list. Issues discovered during the evaluation can be
Hollenbeck Expires December 1, 2014 [Page 3]
Internet-Draft EPP Extension Registry May 2014
corrected by the registrant and those corrections can be submitted to
the designated experts until the designated experts explicitly decide
to accept or reject the registration request. The designated experts
must make an explicit decision and that decision must be shared via
email with the registrant and the eppext mailing list.
Designated experts should be permissive in their evaluation of
requests to register extensions that have been implemented and
deployed by at least one registry/registrar pair. This implies that
it may indeed be possible to register multiple extensions that
provide the same functionality. Requests to register extensions that
have not been deployed should be evaluated with a goal of reducing
functional duplication. A request to register a new, undeployed
extension that duplicates the functionality of an existing, deployed
extension should be rejected with guidance provided to the requestor
to consider the existing, deployed extension.
3.2. Registration Procedure
The registry contains information describing each registered
extension. Registry entries are created and managed by sending forms
to IANA that describe the extension and the operation to be performed
on the registry entry.
3.2.1. Required Information
Name of Extension: A case-insensitive text string that contains the
name of the extension specification.
Specification Location: A URL [RFC3986] that describes the location
of the specification.
Registrant Name and Email Address: The case-insensitive name and
email address of the person that is responsible for managing the
registry entry.
TLDs: A case-insensitive text string description of the top-level
domain (or domains) for which the extension has been specified.
"Any" or "ANY" MUST be used if the extension is not associated with a
specific top-level domain. Multiple TLDs SHOULD be specified as a
list of domain names separated by commas, e.g. ".com, .net".
IPR Disclosure: Either "None", "NONE", or a URL that describes the
location of an IPR disclosure document. Depending on the type of
specification the IPR disclosure MAY be filed with the IETF in
accordance with RFCs 3979 [RFC3979] as updated by RFC 4879 [RFC4879].
Non-IETF IPR disclosures MUST clearly identify the claimed
intellectual property rights and terms of use. "None" or "NONE"
Hollenbeck Expires December 1, 2014 [Page 4]
Internet-Draft EPP Extension Registry May 2014
indicates that the extension is freely available for use with no
claimed intellectual property rights.
Status: Either "Active", "ACTIVE", "Inactive", or "INACTIVE". The
"Active" status is used for extensions that are currently implemented
and available for use. The "Inactive" status is used for extensions
that are not implemented or are otherwise not available for use.
Notes: Either "None", "NONE", or other text that describes optional
notes to be included with the registered extension. If the Status
value is "Inactive" or "INACTIVE" text should be included to describe
how and when this state was reached.
3.2.2. Registration Form
The required information MUST be formatted consistently using the
following form. Form field names and values MAY appear on the same
line:
-----BEGIN FORM-----
Name of Extension:
<text string> (quotes are OPTIONAL)
Specification Location:
<URL>
Registrant Name and Email Address:
<registrant name>, <email address>
TLDs:
"Any"|"ANY"|<one or more TLD text strings separated by commas>
IPR Disclosure:
"None"|"NONE"|<URL>
Status:
"Active"|"ACTIVE"|"Inactive"|"INACTIVE"
Notes:
"None"|"NONE"|<optional text>
-----END FORM-----

Specification Location:
http://tools.ietf.org/html/rfcXXXX
Registrant Name and Email Address:
John Doe, jdoe@example.com
TLDs: Any
IPR Disclosure: None
Status: Active
Notes: None
-----END FORM-----
Example form with non-RFC specification:
-----BEGIN FORM-----
Name of Extension:

John Doe, jdoe@example.com
TLDs: .example
IPR Disclosure:
http://www.example.com/ipr/example-epp-ext-ipr.html
Status: Active
Notes: None
-----END FORM-----
3.2.3. Registration Processing
Each registration form sent to IANA MUST contain a single record for
incorporation into the registry. The form will be sent via email to
<iana@iana.org> by the extension registrant. It MUST have a subject
Hollenbeck Expires December 1, 2014 [Page 6]
Internet-Draft EPP Extension Registry May 2014
line indicating whether the enclosed form represents an insertion of
a new record (indicated by the word "INSERT" in the subject line) or
a replacement of an existing record (indicated by the word "MODIFY"
in the subject line). At no time can a record be deleted from the
registry.
3.2.4. Updating Registry Entries
All changes to existing registry entries MUST be documented with text
in the "Notes" field of the registration form. Under normal
circumstances registry entries MAY only be updated by the registrant.
If the registrant becomes unavailable or otherwise unresponsive the
designated expert MAY submit a registration form to IANA to update
the registrant information. Entries MAY change state from "Active"
to "Inactive" and back again as long as state change requests conform
to the processing requirements identified in this document. Entries
for which a specification becomes consistenly unavailable over time
should be marked "Inactive" by the designated expert until such time
as the specification again becomes reliably available.
4. IANA Considerations
IANA is requested to create a new protocol registry to manage EPP
extensions. The information to be registered and the procedures to
be followed in populating the registry are described in Section 3.
Name of registry: Extensions for the Extensible Provisioning Protocol
Required information: See Section 3.2.1.
Review process: "Specification Required" as described in RFC 5226
[RFC5226].
Size, format, and syntax of registry entries: See Section 3.2.1.
Initial assignments and reservations:

5. Security Considerations
Using email to deliver forms to IANA carries a risk of registry
entries being created or updated by an attacker who is able to spoof
the email address of a legitimate extension registrant. This risk
can be mitigated by replying to received messages with a request to
confirm the requested action. The reply will be delivered to the
specified registrant, who can validate or refute the request.
6. Acknowledgements
The information described in the registry is based on a suggestion
posted to the provreg mailing list by Jay Daley in August 2013.
