Subject:	Meeting reminder and how to review PIM WD14 for 20 March meeting

We have a workshop meeting today at noon Eastern Daylight Time; we rescheduled for today so Michael would be available.

The philosophy that I've followed with the PIM is to select an appropriate and useful subset of the expressive capabilities of RFC 5545 et al + Vavailability. The issues I (and our consumers of the PIM) have right now is how small is still useful.

The key issues to address at this meeting are IMO

(0) Complete issues related to synchronization with Vavailability Internet Draft 05 (it's going to Standards Track soon, but that's our reference).

(1) How much of the recurrence set is necessary for Vavailability? We started with RRules, and then based on comments added EXDATE (Exception Dates to the recurrence). RDATE which are recurrence dates that don't fit a a pattern - and share the same _expression_ as EXDATE. So RRules, Rdate, and Exdate  - see section 3.8.5 (p118) of RFC5545 for background for our discussion.

(2) Should recurrence be attached to Gluons? There was a proposal to apparently add recurrence values to Intervals, which I believe I mistook from a comment. On further thought, recurrence of intervals confuses the semantics considerably; one could conceive of a use for recurrence on a gluon, which effectively shadows the gluon with a potentially unbounded number of additional gluons reflecting future instances of a business process.  I have mixed feelings about the value of the this versus the additional complexity for M2M interpretation, which is another touchstone for PIM inclusion. Also relates to https://issues.oasis-open.org/browse/WSCALENDAR-555

Thanks!

I suggest this order for your review of WD14. All links are public:

• The Diffmarked PDF (https://www.oasis-open.org/committees/download.php/55258/ws-calendar-pim-v1.0-diff-wd14-wrt-wd13.pdf ) 6MB
  
• The Figures only (https://www.oasis-open.org/committees/download.php/55252/PIM_WD14_Figures.zip )  1MB
  
• The Clean PDF (https://www.oasis-open.org/committees/download.php/55259/ws-calendar-pim-v1.0-wd14.pdf ) 5MB
• If you use Enterprise Architect, the EAP file (https://www.oasis-open.org/committees/download.php/55254/PIM_WD14_20150312.eap.zip ) 500K
  

Changes are fairly well limited, and concentrated in the Vavailability areas.

You should also look at all non-closed Jira items for PIM; WD14 addresses nearly all of them. Search for issues on component PIM in states except CLOSED.

Please add comments in Jira as you see fit - that will help the Workshop meeting on March 20 go faster if we digest the discussion in advance.

Here are direct links to the items; a bunch are "align with Vavailability Internet Draft 05" and are subissues linked from WSCALENDAR-541 (and not separately listed here).  Most are based on comments received from Steve Ray on behalf of the ASHRAE Facility Smart Grid Information Model team, which is doing UML models for that purpose and is extensively using the PIM CS01, and most of the rest are based on Toby, Mike, and my reading and discussion of related issues.

Some of the following are resolved but not applied, e.g. https://issues.oasis-open.org/browse/WSCALENDAR-558

1. https://issues.oasis-open.org/browse/WSCALENDAR-541 container for 11 subtasks shows as "Open" because some subtasks are open
   
2. https://issues.oasis-open.org/browse/WSCALENDAR-544
3. https://issues.oasis-open.org/browse/WSCALENDAR-550
4. https://issues.oasis-open.org/browse/WSCALENDAR-551
5. https://issues.oasis-open.org/browse/WSCALENDAR-557
6. https://issues.oasis-open.org/browse/WSCALENDAR-558

Open and need comments and proposed resolution text:

1. https://issues.oasis-open.org/browse/WSCALENDAR-540
   
2. https://issues.oasis-open.org/browse/WSCALENDAR-555
3. https://issues.oasis-open.org/browse/WSCALENDAR-563

Thanks!
