Harry,
 
I  think  the idea was  that the primary operations are  those that I  identified. The list below  (subject to consideration) would be contained within the response   to  GetSchedule.  It  is not  clear  to me if  we  can  describe them  all at the  same level. But the fact  is that the  management server can not  directly  initiate any operation through   the management  agent. it can  only respond  to a management agent query for  instructions, that  is GetSchedule.

So the list of operations I currently have is 

Disable 
Enable 
Pause 
Resume 
Activate 
Purge 
Reset 
PowerOff 
GetAttributes 
SetAttributes 
GetResource 
SetResource 
Register 
Unregister 

We are still toying with the concept of an "Execute" for extensibility if nothing else (right?) 

And this current thread is about adding GetSchedule, SendReport, and SendNotification (or SendAlert) 

Right? 

Should we be considering Schedule as a Resource (GetResource vs Get Schedule)? Is a report really GetAttributes?

Hi Bill,

IPP "SendNotification" is used for Printer alerts (not just
Job notifications).  If we keep both, then the PWG Semantic
Model has to model them both and clarify when to use one
or the other.

And if a "routine" notification is sent to a WBMM Manager,
then it's not properly an alert (an exception notification),
right?

Cheers,
- Ira

Ira,

I  toyed with  both "accept'  and  "Send".   I guess I left it thinking of
these  as commands,  with  the  result  indicated. I have  no  problem with
the  "SendReport".  approach and agree that it is better.

I still think that the  WBMM "SendAlert" is, at most, a special case of the
more general "SendNotification"  both in content and use (I could not see a
WBMM Managment Application
being notified  when a job was done, let alone when each page drops).
Although there  may be some similarity, I think it better to preserve a name
distinction.

Hi Bill,

Comments about your operation names:

(1) 'GetSchedule' is fine.
(2) 'AcceptReport' I don't like - the verb should describe the action
   of the Sender - I suggest (following IPP Notifications) we use
   'SendReport'.
(3) 'AcceptAlert' - same comment - I suggest 'SendAlert' or (closer
   to IPP Notifications) 'SendNotification'.

PS - I actually _am_ working on XML schema for a Schedule object and 
an Action object (row in a schedule).  I'm looking at the very mature
IETF Schedule MIB (RFC 3231, October 2002, which obsoletes RFC 2591):

"Abstract

  This memo defines a portion of the Management Information Base (MIB)
  for use with network management protocols in the Internet community.
  In particular, it describes a set of managed objects that are used to
  schedule management operations periodically or at specified dates and
  times."

Ira,

Considering what  I  was calling  the "connections" as the  initial
operations requested in the  Post by  the  managed  object, these
operations  would  be called;

Get  Schedule  (arguments  include  ID  of  device  or proxy  [which
represents  a  group  of  devices])
(Accept) Periodic report
(Accept) Alert Report  (notification)

The schedule  would  consist  of  one  or  more of  what we have been
previously calling  operation  requests  (e.g.,  get  element), qualified
by time,  condition and (to accommodate  proxies)  actual  managed  object
ID.  The time could be immediate,  in which  case  you  would have the
exchange:
   
Managed Object
Manager
Open connection or  send initial mail  message
                               ----------------------Get
Schedule------------------------------>

                             <----Schedule  (get-element X, device y,
immediate)---
      
                             -----Accept  Report  (element X value, device
y)--------->

                             <---------------------------Report
Accepted------------------------

                              ----------------------Get
Schedule------------------------------>

                              <-------Schedule (send next Get  Schedule
[time], end)-----

close connection  or  cease POP polling



Perhaps  we  could also  allow that  a Schedule can be the response  to  an
Accept  Report. That would simplify an exchange to:

Managed Object
Manager
                               ----------------------Get
Schedule------------------------------>

                             <----Schedule  (get-element X, device y,
immediate)---
      
                             -----Accept  Report  (element X value, device
y)--------->

                             <----Schedule  (get-element Z, device y,
immediate)---
      
                             -----Accept  Report  (element X value, device
y)--------->
                        
                              <-------Schedule (send next Get  Schedule
[time], end)-----


I   am uncertain  if  we  can represent  the  operation  commands contained
within the Get  Schedule  operation response in the same was as  the  Get
Schedule, Accept  Report and Accept Alert operations.
