[Smwg] Small topic for today's telecon

[Barkley, Erik J (3970)]

Thank you Marcin,

The diagram helps a lot.  Yes, I agree that 0..* cardinality will be better than 1..* in this case.   Let's see if everyone else agrees at the Feb 6th webex.

Best regards,
-Erik

Hi Erik & group,

I should be there on February 6th. So that would be fine.

Regarding another point:

[cid:image001.jpg at 01D39043.52C299D0]

We discovered, that it may be thinkable that someone sends a request to deliver all Service Packages from specific time frame. And maybe in that time frame there will be no actual SP's. So it should maybe be possible to have "empty" ServicePackageResult (0..* -> you know... it's not an "error" it any sense, so no something like "failed return", but rather "look, you asked for specific time, and there is "nothing"). We may discuss that. I know we dive here actually into the behavioral things of the Service Management, but I think we can't really escape that...

Marcin

Hello Marcin,

As you could probably tell we ran out of time before we could look at the state machine. Also, I suspect that with the Christmas and New Year's holidays etc. people were probably not really in a proper state of mind to look at the state machine :-)  In any case, I propose that we put the state machine review on the agenda for the next teleconference.  Will you be available to help guide the discussion on February 6?

I'm not quite sure what you mean by not allowing the return of an empty list.  Can you clarify a bit?

Best regards,
-Erik

Hi,

I have only two topics we may shortly touch upon today:

-          State Machine (did anyone looked at the stuff, any thoughts)....

-          Small comment according Service Package Result: as of up-to-now version of the diagram, the Service Package entity does not allow to return an empty list. It should however.

Best Regards
Marcin
