[Morris Riedel]

Steven, all,

  first and foremost thank you for your valuable comments Steven.

I put your comments in the working slides to be more effectively discussed and tracked.

The discussion of this e-mail is on the agenda today.

Take care,
Morris

>-All,
>-
>-Some good progress seems to be being made on the specification and the draft is beginning to become coherent. A few thoughts
emerged
>-following a quick read through.
>-
>-* ChangeActivityState
>-This reminded me of discussions we had in the late stages of BES. A similar operation was moved in  & out of the draft before
finally being
>-removed. There was discomfort as to the amount of influence an end-user agent could have on the underlying state machine. A user
could not
>-force a job to execute if it was queued if there were not processes available. With the expanded state model that is now proposed
there is more
>-scope for user control - fine. You have the notion of legal and illegal state change requests but I could not see these documented
on the state
>-diagram. I would certainly propose changing this to 'RequestActivityStateChange' to make it clear that this is an initiation and
that it make take
>-some time for the underlying state engine to change. You effectively acknowledge this in your estimated time to change return
value.
>-
>-I can see it being useful to have a 'this has already been done' option in the return body. I'm not sure how useful any value
other than zero
>-effectively is here. To me you are effectively saying this has either been done or you need to set up a notification or a poll to
check back to see
>-when it has completed. The estimate itself does not seem to be that valuable...
>-
>-* Partitioning
>-The three port types all seem sensibly scoped. I have great concerns about the AGU-JSDL section. I'm not sure if this is just a
place holder at
>-the moment. I would be VERY concerned if this AGU-JSDL forks away from the JSDL activity. JSDL has gained considerable traction
and is
>-being further developed in the JSDL 2.0 discussions. I would have thought PGI would be better placed supporting a MINIMAL
extension to
>-JSDL to support its immediate needs, and feeding the other improvements it could see being needed into the broader JSDL
discussions.
>-
>-* Delegation & Information PortTypes
>-This must have broader use than just beyond PGI. If there are opportunities to do this why not put these into separate
specifications even if
>-they are still done through the PGI-WG.
