Carl-Uno said we could have 15 minutes on the joint IPP/JMP job-state
and job-state-reasons issues (see attached).


JMP people, please call in, so we can put these issues to bed for both
IPP and JMP.


(NOTE - the entire document is NOT included in the e-mail.  You should
fetch at least the .pdf file without revison marks (jobstate.pdf) from the
ftp server).


Thanks,
Tom

>This document is the updated IPP "job-state" and "job-state-reasons"
attributes and the corresponding JMP jmJobState and jmJobStateReasons1 objects
>from the IPP telecon, of Wednesday, May 27.  There we agreed to having 7
states in common between IPP and JMP:  pending, pending-stopped, processing,
processing-stopped, canceled, aborted, and completed.  The JMP values of the
jmJobStateReasons1 object are a superset of the IPP values of the
"job-state-reasons" attribute.

>JOINT IPP/JMP ISSUE - Should we go back to the name 'held', instead of
'pending-stopped'?
>
>The IPP protocol has a "job-hold-until", so having the name of the state be
'held' aligns with that name better making it clearer to the user the
relationship between the attribute and the state.  Also some current systems
have a 'held' state, so that current practice for system that have such as
state is to call that state 'held'.  Also the ISO DPA has a 'held' state.
>Finally, our sub-classing in the names doesn't work for 'completed', since
we have 'aborted' and 'canceled', not 'completed-aborted' and
'completed-canceled', so why have it for pending-stopped, which may prove
fairly startling to a user, while 'held' is readily understandable.

>Here is the summary of the job state and job state reasons agreements:
>
>1. In JMP remove the 'printing' state.
>
>2. Rename the JMP 'held' state to 'pending-stopped' and rename the JMP
state 'needsAttention' to 'processingStopped'.

>3. In both IPP and JMP add the 'aborted' state and make it a final state.

>4. In both IPP and JMP remove the 'aborted-by-system' job-state-reason,

>
>5. In IPP replace the 'terminating' state with the 'canceled' and 'aborted'
>states and make 'canceled' and 'aborted' final states, like the
>JMP 'canceled' and 'completed' states.
>
>6. Since the pending-stopped state has been added, JMP no longer needs a
generic jobHeld job state reason.

transitions are unlikely, but are not forbidden.
