Internet Printing Protocol (IPP): Event Notifications and Subscriptions
draft-ietf-ipp-not-spec-12

The IESG has approved the following Internet-Drafts as Proposed
Standards: 

o "Internet Printing Protocol (IPP): Event Notifications and
  Subscriptions" <draft-ietf-ipp-not-spec-11.txt>
o "Internet Printing Protocol (IPP): The 'ippget' Delivery Method for
  Event Notifications" <draft-ietf-ipp-notify-get-09.txt>

The IESG also approved publication of "Internet Printing Protocol:
Requirements for IPP Notification" <draft-ietf-ipp-not-06.txt> as
an Informational RFC.

These documents are the product of the Internet Printing Protocol
Working Group.  The IESG contact persons are Ned Freed and Ted Hardie.


Technical Summary

  These documents describe extensions to the Internet Printing Protocol/1.1:
  Model and Semantics (RFC 2911, RFC 2910). The first extension allows a
  client to subscribe to printing related Events.  Subscriptions are modeled
  as Subscription Objects.  The Subscription Object specifies that when one
  of the specified Events occurs, the Printer delivers an asynchronous Event
  Notification to the specified Notification Recipient via the specified
  Push or Pull Delivery Method (i.e., protocol).

  The second extension is the 'ippget' Pull Delivery Method for use with the
  Event Notifications extension. This IPPGET Delivery Method is REQUIRED for
  all clients and Printers that support ipp-ntfy.  The Notification Recipient,
  acting as a client, fetches (pulls) Event Notifications using the
  Get-Notifications operation.

  The final document in this set provides a statement of the requirements for
  notifications as part of an IPP service.

Working Group Summary

  These documents are products of the Internet Printing Protocol Working
  Group of the IETF. The Working Group originally developed a general
  printer notification framework and three notification schemes, two
  based on IPP operations and one based on email. However, a previous
  IESG review pass caused the working to eliminate two of the schemes and
  move forward with ippget alone.

Protocol Quality

  Ned Freed reviewed the specification for the IESG.
