[Oslc-Automation] Availability Spec review - were all the previous comments covered?

Most of the comments were in theperiod running up to this meeting: 
http://open-services.net/wiki/automation/AutomationMeetings20140515/

The main comment in the minutes from that meeting about this was "We 
agreed to do scenario-driven bottom-up design, only adding terms that are 
needed by scenarios. ". I think there are still some items in the spec 
that could come out as they're not required for some of the scenarios. (If 
there are any predicates/properties that you think would be useful, but 
aren't needed for the scenarios, then just list these somewhere - perhaps 
in an appendix of the spec (for now) or - better - just on the wiki page. 
Putting them in the spec will cause more work, as we have to ask 'how do 
consumers know how to use it'. Then we can decide what to do with them 
separately.)

You can verify what's needed by the scenarios by writing out how a 
consumer (& provider) uses the data for each of the scenarios, and ticking 
off each property in the spec as it's used. perhaps even linking from the 
spec, saying "See an example of how this is used in the X scenario" 
(although we don't do that elsewhere).

(Even if all the predicates still i there are really needed, having this 
information about how they're used would help us as reviewers see that 
they're needed.)

I think all the comments from the mailing list should be here: 
http://open-services.net/pipermail/oslc-automation_open-services.net/2014-May/
It does look like you've addressed most of my ones, but I can't speak for 
John.

From 
http://open-services.net/pipermail/oslc-automation_open-services.net/2014-May/000743.html:
"You don't have any text about achieving any of those scenarios..."
You do seem to have addressed this to some degree in the section "Updating 
the condition of an AvailabilityResource", but it's still not enough for a 
client to programatically start or stop the resource. (The client checks 
the current state, it doesn't match what they want, so they follow 
oslc:action and... can they expect just one action there? What if there 
are many? Even if there's one action they don't know if it's an action to 
start the resource, or to delete the resource or change its redundancy 
level, make it the primary resource, etc, etc. Even if it's a single 
action to do all of them, they don't know how to use its parameters to 
configure it to do one over the other.)

I don't have time to look over more of those comments right now to pick 
out any that were completely missed.
