RE: [ws-calendar-comment] Comment on PIM 1.0 CS01 09 October 2014

["Considine, Toby" <Toby.Considine@unc.edu>]

This is not a pre-judgment on the comment, because I sense that as well. ASHRAE scenarios not only frequently require times w/ or w/o time zones, but w or w/o DST as well. Business hours may need an opening at 8”00 in whatever the local time zone is, automatically adjusting for DST.

 

As to availability, there are a number of ways to express “every Tuesday…

 

 

There is Every 7 days starting with *this* Tuesday

There is weekly, occurring on *these* days of the week

And so on.

 

 

I have particularly considered the sort of scenarios you talk about for live energy models. A live energy model is grounded in hard dates, the projected energy model may well be based on days of the week with no starting date indicated yet.

 

Of course, this is a PIM, and it may be that these issues are best addressed in a PSM. A couple of us have been toying with a Minimal PSM (in XSD) that expresses the PIM UML model and might make allowances for the flexibility you indicate.

 

None of this is speaking ex cathedra. We, as a TC, have not discussed your comments. This is just a first reaction to your comment. Thanks for submitting it.

Please consider adding a Date class (Date without time, perhaps with Time Zone) and a Time class (Time without date, perhaps with Time Zone) to the model. This would be useful in models [ASHRAE SPC201] that we are currently working with.

It is not clear how one would express (say) an availability of "every Tuesday" for Availability. Can the specification express time of day with day of week, say "8am, Monday through Friday"?
