    8   Change Poll Extension for the Extensible Provisioning Protocol (EPP)

   12    This document describes an Extensible Provisioning Protocol (EPP)       
   13    extension for notifying clients of operations on client-sponsored       
   14    objects that were not initiated by the client through EPP.  These       
   15    operations may include contractual or policy requirements including,    
   16    but not limited to, regular batch processes, customer support           
   17    actions, Uniform Domain-Name Dispute-Resolution Policy (UDRP) or        
   18    Uniform Rapid Suspension (URS) actions, court-directed actions, and     
   19    bulk updates based on customer requests.  Since the client is not       
   20    directly involved or knowledgable of these operations, the extension    
   21    is used along with an EPP object mapping to provide the resulting       
   22    state of the postoperation object, and optionally a preoperation        
   23    object, with the operation metadata of what, when, who, and why.        
   24

  112                                                                            
  113    This document describes an extension mapping for version 1.0 of the     
  114    Extensible Provisioning Protocol (EPP) [RFC5730].  This mapping, an     
  115    extension to EPP object mappings like the EPP domain name mapping       
  116    [RFC5731], is used to notify clients of operations they are not         
  117    directly involved in, on objects that the client sponsors.  It is up    
  118    to server policy to determine what transform operations and clients     
  119    to notify.  Using this extension, clients can more easily keep their    
  120    systems in sync with the objects stored in the server.  When a change   
  121    occurs that a client needs to be notified of, a poll message can be     
  122    inserted by the server for consumption by the client using the EPP      
  123    <poll> command and response defined in [RFC5730].  The extension        
  124    supports including a "before" operation poll message and an "after"     
  125    operation poll message.  The extension only extends the EPP <poll>      
  126    response in [RFC5730] and does not extend the EPP <poll> command.       
  127    Please refer to [RFC5730] for information and examples of the EPP       
  128    <poll> command.                                                         
  129                                                                            
  130 1.1.  Conventions Used in This Document                                    
  131

  133    "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and    
  134    "OPTIONAL" in this document are to be interpreted as described in       
  135    BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all      
  136    capitals, as shown here.                                                
  137                                                                            
  138    XML is case sensitive.  Unless stated otherwise, XML specifications     
  139    and examples provided in this document MUST be interpreted in the       
  140    character case presented in order to develop a conforming               
  141    implementation.                                                         
  142                                                                            
  143    In examples, "C:" represents lines sent by a protocol client, and       
  144    "S:" represents lines returned by a protocol server.  Indentation and   
  145    white space in examples are provided only to illustrate element         
  146    relationships and are not a REQUIRED feature of this protocol.          
  147                                                                            
  148    The XML namespace prefix "changePoll" is used for the namespace         
  149    "urn:ietf:params:xml:ns:changePoll-1.0", but implementations MUST NOT   
  150    depend on it; instead, they should employ a proper namespace-aware

  174    An operation consists of any transform operation that impacts objects   
  175    that the client sponsors and should be notified of.  The                
  176    <changePoll:operation> element defines the operation.  The OPTIONAL     
  177    "op" attribute is an identifier, represented in the 7-bit US-ASCII      
  178    character set defined in [RFC20], that is used to define a sub-         
  179    operation or the name of a "custom" operation.  The enumerated list     
  180    of <changePoll:operation> values is:

  184    "delete":  Delete operation as defined in [RFC5730].  If the delete     
  185        operation results in an immediate purge of the object, then the     
  186        "op" attribute MUST be set to "purge".                              
  187

  190    "transfer":  Transfer operation as defined in [RFC5730] that MUST set   
  191        the "op" attribute with one of the possible transfer-type values;   
  192        these include "request", "approve", "cancel", or "reject".          
  193

  196    "restore":  Restore operation as defined in [RFC3915] that MUST set     
  197        the "op" attribute with one of the possible restore-type values;

  200    "autoRenew":  Auto renew operation executed by the server.              
  201                                                                            
  202    "autoDelete":  Auto delete operation executed by the server.  If the    
  203        "autoDelete" operation results in an immediate purge of the         
  204        object, then the "op" attribute MUST be set to "purge".             
  205                                                                            
  206    "autoPurge":  Auto purge operation executed by the server when          
  207        removing the object after it has had the status "pendingDelete".    
  208                                                                            
  209    "custom":  Custom operation that MUST set the "op" attribute with the   
  210        custom operation name.  The custom operations supported are up to   
  211        server policy.

  219

  221 2.2.  State                                                                
  222                                                                            
  223    The state attribute reflects the state of the object "before" or        
  224    "after" the operation.  The state is defined using the OPTIONAL         
  225    "state" attribute of the <changePoll:changeData> element, with the      
  226    possible values "before" or "after" and a default value of "after".     
  227    The server MAY support both the "before" state and the "after" state    
  228    of the operation by using one poll message for the "before" state and   
  229    one poll message for the "after" state.  The "before" state poll        
  230    message MUST be inserted into the message queue prior to the "after"    
  231    state poll message.                                                     
  232                                                                            
  233    For operations in Section 2.1 that don't have an "after" state, the     
  234    server MUST use the "before" state poll message.  For example, for      
  235    the "delete" operation with the "op" attribute set to "purge", or the   
  236    "autoPurge" operation, the server includes the state of the object      
  237    prior to being purged in the "before" state poll message.               
  238                                                                            
  239    For operations in Section 2.1 that don't have a "before" state, the     
  240    server MUST use the "after" state poll message.  For example, for the   
  241    "create" operation, the server includes the state of the object after   
  242    creation in the "after" state poll message.                             
  243                                                                            
  244 2.3.  Who                                                                  
  245                                                                            
  246    The <changePoll:who> element defines who executed the operation, for    
  247    audit purposes.  It is a free-form value that is meant strictly for     
  248    audit purposes and not to drive client-side logic.  The scheme used     
  249    for the possible set of <changePoll:who> element values is up to        
  250    server policy.  The server MAY identify the <changePoll:who> element    
  251    value based on:                                                         
  252                                                                            
  253    "Identifier":  Unique user identifier of the user that executed the     
  254        operation.  An example is "ClientX".                                
  255                                                                            
  256    "Name":  Name of the user that executed the operation.  An example is   
  257        "John Doe".

  259    "Role":  Role of the user that executed operation.  An example is       
  260        "CSR" for a Customer Support Representative or "Batch" for a        
  261        server batch.

  299    This extension does not add any elements to the EPP <info> command      
  300    described in [RFC5730].

  302    This extension adds operational detail of EPP object-mapping            
  303    operations (Section 2.1) to an EPP poll response, as described in       
  304    [RFC5730].  It is an extension of the EPP object-mapping info           
  305    response.  Any transform operation to an object defined in an EPP       
  306    object mapping by a client other than the sponsoring client MAY         
  307    result in extending the <info> response of the object for inserting     
  308    an EPP poll message with the operation detail.  The sponsoring client   
  309    will then receive the state of the object with operation detail like    
  310    what, who, when, and why the object was changed.  The                   
  311    <changePoll:changeData> element contains the operation detail along     
  312    with an indication of whether the object reflects the state before or   
  313    after the operation as defined in Section 2.2.  The                     
  314    <changePoll:changeData> element includes the operation detail with      
  315    the following child elements:                                           
  316                                                                            
  317    <changePoll:operation>:  Transform operation executed on the object,    
  318        as defined in Section 2.1.                                          
  319                                                                            
  320    <changePoll:date>:  Date and time when the operation was executed.      
  321                                                                            
  322    <changePoll:svTRID>:  Server transaction identifier of the operation.
