Change Poll Extension for the Extensible Provisioning Protocol (EPP)
draft-ietf-regext-change-poll-04
Abstract
This document describes an Extensible Provisioning Protocol (EPP)
extension for notifying clients of operations on client sponsored
objects that were not initiated by the client through EPP. These
operations MAY include contractual or policy requirements including
but not limited to regular batch processes, customer support actions,
Uniform Domain-Name Dispute-Resolution Policy (UDRP) or Uniform Rapid
Suspension (URS) actions, court directed actions, and bulk updates
based on customer requests. Since the client is not directly
involved or knowledgable of these operations, the extension is used
along with an EPP object mapping to provide the resulting state of
the post-operation object, and optionally a pre-operation object,
with the operation meta-data of what, when, who, and why.

1. Introduction
This document describes an extension mapping for version 1.0 of the
Extensible Provisioning Protocol (EPP) [RFC5730]. This mapping, an
extension to EPP object mappings like the EPP domain name mapping
[RFC5731], is used to notify clients of operations they are not
directly involved in, on objects that the client sponsors. It is up
to server policy to determine what transform operations and clients
to notify. Using this extension clients can more easily keep their
systems in-sync with the objects stored in the server. When a change
occurs that a client needs to be notified of, a poll message can be
inserted by the server for consumption by the client using the EPP
<poll> command and response defined in [RFC5730]. The extension
supports including a "before" operation poll message and an "after"
operation poll message.
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.
"changePoll-1.0" is used as an abbreviation for
"urn:ietf:params:xml:ns:changePoll-1.0". The XML namespace prefix
"changePoll" 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
This extension adds additional elements to EPP object mappings like
the EPP domain name mapping [RFC5731]. Only those new elements are
described here.
2.1. Operation
An operation consists of any transform operation that impacts objects
that the client sponsers and SHOULD be notified of. The
<changePoll:operation> element defines the operation. The OPTIONAL
"op" attribute is used to define a sub-operation or the name of a
"custom" operation. The enumerated list of <changePoll:operation>
values include:
"create" Create operation as defined in [RFC5730].
"delete" Delete operation as defined in [RFC5730]. If the delete
operation results in an immediate purge of the object, then the
"op" attribute MUST be set to "purge".
"renew" Renew operation as defined in [RFC5730].
"transfer" Transfer operation as defined in [RFC5730] with the
OPTIONAL "op" attribute defining the transfer type with the
possible values of "request", "approve", "cancel", and "reject".
"update" Update operation as defined in [RFC5730].
"restore" Restore operation as defined in [RFC3915] with the
OPTIONAL "op" attribute defining the restore type with the
possible values of "request" and "report".
"autoRenew" Auto renew operation executed by the server.
"autoDelete" Auto delete operation executed by the server. If the
"autoDelete" operation results in an immediate purge of the
object, then the "op" attribute MUST be set to "purge".
"autoPurge" Auto purge operation executed by the server when
removing the object after it had the "pendingDelete" status.
"custom" Custom operation that uses the "op" attribute to define the
custom operation name.
2.2. Who
Who defines who executed the operation for audit purposes, and is
represented using the <changePoll:who> element. The scheme used for
the possible set of Who values is up to server policy. The server
MAY identify Who based on:
"Identifier" Unique user identifier of the user that executed the
operation. An example is "ClientX".
"Name" Name of the user that executed the operation. An example is
"John Doe".
Gould & Feher Expires April 21, 2018 [Page 4]
Internet-Draft changePoll October 2017
"Role" Role of the user that executed operation. An example is
"CSR" for a Customer Support Representative or "Batch" for a
server batch.
3. EPP Command Mapping
A detailed description of the EPP syntax and semantics can be found
in the EPP core protocol specification [RFC5730].
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 [RFC5730].
3.1.2. EPP <info> Command
This extension does not add any elements to the EPP <info> command
described in the [RFC5730].
This extension adds transaction detail of the operations to the EPP
<info> poll response, as described in [RFC5730], of an EPP Object
Mapping like [RFC5731]. Any transform operation to an object defined
in an EPP Object Mapping, by a client other than the sponsoring
client, MAY result in extending the <info> response of the object for
inserting an EPP poll message with the operation detail. The
sponsoring client will then receive the state of the object with
operation detail like what, who, when, and why the object was
changed. The <changePoll:changeData> element contains the operation
detail along with an indication of whether the object reflects the
state before or after the operation, using the OPTIONAL "state"
attribute, with the possible values of "before" or "after", and with
a default value of "after". The "state" attribute describes the
state of the response data or <resData> block returned in the poll
response. The server MAY support providing the "before" state and
"after" state to the operation, by using one poll message for the
"before" state and one poll message for the "after" state. When
using the "before" state poll message, it MUST be inserted prior to
the "after" state poll message. The <changePoll:changeData> element
includes the operation detail with the following child elements:
Gould & Feher Expires April 21, 2018 [Page 5]
Internet-Draft changePoll October 2017
<changePoll:operation> Transform operation executed on the object as
defined in Section 2.1.
<changePoll:date> Date and time when the operation was executed.
<changePoll:svTRID> Server transaction identifier of the operation.
<changePoll:who> Who executed the operation as defined in
Section 2.2.
<changePoll:caseId> OPTIONAL case identifer associated with the
operation. The required "type" attribute defines the type of
case with an enumerated list of case types including:
udrp a Uniform Domain-Name Dispute-Resolution Policy (UDRP)
case.
urs a Uniform Rapid Suspension (URS) case.
custom A custom case that is defined using the "name" attribute.
<changePoll:reason> OPTIONAL reason for executing the operation. If
present, this element contains the server-specific text to help
explain the reason the operation was executed. 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 the default value of "en" (English).
Example poll <info> response with the <changePoll:changeData>
extension for a URS lock transaction on the domain.example domain
name, with the "before" state. The "before" state is reflected in
the <resData> block:

One schema is presented here that is the EPP Change Poll Extension
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.

5. IANA Considerations
5.1. XML Namespace
This document uses URNs to describe XML namespaces and XML schemas
conforming to a registry mechanism described in [RFC3688]. The
following URI assignment is requested of IANA:
URI: urn:ietf:params:xml:ns:changePoll-1.0
Registrant Contact: See the "Author's Address" section of this
document.
XML: See the "Formal Syntax" section of this document.
Gould & Feher Expires April 21, 2018 [Page 18]
Internet-Draft changePoll October 2017
5.2. EPP Extension Registry
The EPP extension described in this document should be registered by
the IANA in the EPP Extension Registry described in [RFC7451]. The
details of the registration are as follows:
Name of Extension: "Change Poll Extension for the Extensible
Provisioning Protocol (EPP)"
Document status: Standards Track
Reference: (insert reference to RFC version of this document)
Registrant Name and Email Address: IESG, <iesg@ietf.org>
TLDs: Any
IPR Disclosure: None
Status: Active
Notes: None
6. Implementation Status
Note to RFC Editor: Please remove this section and the reference to
RFC 6982 [RFC6982] before publication.
This section records the status of known implementations of the
protocol defined by this specification at the time of posting of this
Internet-Draft, and is based on a proposal described in RFC 6982
[RFC6982]. The description of implementations in this section is
intended to assist the IETF in its decision processes in progressing
drafts to RFCs. Please note that the listing of any individual
implementation here does not imply endorsement by the IETF.
Furthermore, no effort has been spent to verify the information
presented here that was supplied by IETF contributors. This is not
intended as, and must not be construed to be, a catalog of available
implementations or their features. Readers are advised to note that
other implementations may exist.
According to RFC 6982 [RFC6982], "this will allow reviewers and
working groups to assign due consideration to documents that have the
benefit of running code, which may serve as evidence of valuable
experimentation and feedback that have made the implemented protocols
more mature. It is up to the individual working groups to use this
information as they see fit".
