[WIMS] Re: Proposal - Power Log only on System object

Hi,

We didn't quite have a quorum today for our WIMS WG call
(Bill W, Lee F, Rick L, Ira McD).  So there won't be official
minutes.

But, we talked about Power Log group - Rick provided some
relevant recent DMTF CIM modeling experience (not PWG).

So we decided to make Power Log *only* occur on System
object - to avoid having to crawl through references in the
various Subunit objects (some of which might be powered
down - eek!).

So add PowerComponentType andPowerComponentID to
the Power Log group.  Values of PowerComponentTypeWKV
will be aligned with values of PrtAlertCodeTC (Printer MIB)
and IcSubunitTypeTC (Counter MIB).  Basically, System plus
every PWG Semantic Model first-class Subunit type - not
MarkerSupplies or specific Finisher types (Stapler, etc.).

We also talked about allowing the Power Management
Model groups (except Power General and Power Log)
to be instantiated on *any* Subunit (not just the major
hardware ones).  Also adding an ambiguity warning about
the corner case (Interpreter - software - similar to Service).

I plan to release a new version of the Power Management
Model this week that reflects these changes.

Cheers,
- Ira
