Change Poll Extension for the Extensible Provisioning Protocol (EPP)
draft-ietf-regext-change-poll-06
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.

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] that MUST set
the "op" attribute with one of the possible transfer type values
that include "request", "approve", "cancel", or "reject".
"update": Update operation as defined in [RFC5730].
"restore": Restore operation as defined in [RFC3915] that MUST set
the "op" attribute with one of the possible restore type values
that include "request" or "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 MUST set the "op" attribute with the
custom operation name.
2.2. State
The state attribute reflects the state of the object "before" or
"after" the operation. The state is defined using the OPTIONAL
"state" attribute of the <changePoll:changeData> element, with the
possible values "before" or "after" and with a default value of
"after". The server MAY support both the "before" state and the
"after" state of the operation, by using one poll message for the
"before" state and one poll message for the "after" state. The
"before" state poll message MUST be inserted prior to the "after"
state poll message.
Gould & Feher Expires July 9, 2018 [Page 4]
Internet-Draft changePoll January 2018
For operations in Section 2.1 that don't have an "after" state, the
server MUST use the "before" state poll message. For example, for
the "delete" operation with the "op" attribute set to "purge", or the
"autoPurge" operation, the server includes the state of the object
prior to being purged in the "before" state poll message.
For operations in Section 2.1 that don't have a "before" state, the
server MUST use the "after" state poll message. For example, for the
"create" operation, the server includes the state of the object after
creation in the "after" state poll message.
2.3. Who
The <changePoll:who> element defines who executed the operation for
audit purposes. The scheme used for the possible set of
<changePoll:who> element values is up to server policy. The server
MAY identify the <changePoll:who> element value 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".
"Role": Role of the user that executed operation. An example is
"CSR" for a Customer Support Representative or "Batch" for a
server batch.
2.4. 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
[W3C.REC-xmlschema-2-20041028] 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].
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.
Gould & Feher Expires July 9, 2018 [Page 5]
Internet-Draft changePoll January 2018
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 operation detail of EPP object mapping operations
Section 2.1 to an EPP poll response, as described in [RFC5730], that
is an extension of the EPP object mapping info response. 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 as defined in
Section 2.2. The <changePoll:changeData> element includes the
operation detail with the following child elements:
<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 2.3.
<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).

4. Formal Syntax
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.
