I share your frustration that we were left hanging about CIM Core
working contacts and CR guidance.
I guess we try to write a 'low hanging fruit' CR (editorial only).
We could decide NOT to deprecate the misplaced 'default-xxx' properties
in CIM_Printer and just revise their descriptions to warn that
authoritative info can be found in their sibling properties in
We could warn that 'current-xxx' properties were inherently ambiguous
and therefore 'implementation-dependent'.
That's sort of a diplomatic course that treats as editorial what we
think were mistakes, without stepping on the toes of any previous
implementors or CR submitters.

Subject: WIMS> CIM> A few notes from today's concall with CIM Core WG
The concall today went reasonably well, and we got much more than our
allotted fifteen minutes of fame. Still didn't quite get thru it all, but
Comments that I heard and noted during the discussion.
- Adding properties to PrintService, no problem. Deprecating properties is
harder. We may get pushback from some people who have already implemented
them, like parts of IBM or HP.
- Need to find out what the history of the changes was. It's their
impression that all the changes were made on behalf of PWG by some champion
in Core. John Crandall will get hold of Steve Jerman.
- For some items such as consoles, covers, channels, maybe counters, it will
likely be better to write a profile that describes how to use existing
classes to model these items. Need to check on the availability of suitable
- Language interpreter might be modeled with SoftwareIdentity; not entirely
- For some items, we can probably use the Capabilities and Settings classes
and mechanism already in CIM. [Might be reasonable for paper sizes, media
- We should take a look at the Profile User's Guide for guidance. [I'll try
to find it.]
Overall, the topic ended very abruptly and I felt left hanging. We need a
working contact or two within Core who can do the education back and forth
about CIM and Printers. We need to look at doing the editorial changes as
"low hanging fruit first." We need to discuss process. They did not seem
to disagree with the scope, but the next steps were not clear to me. Harry,
Ira, et al., do you understand better how to proceed?
