Hi,
By the way, the corresponding IPP Printer attributes are called
'charset-configured' and 'natural-language-configured'. Given that
IPP and the Printer MIB frequently refer to the 'current configuration',
DMTF CIM property names of 'Current...' are fine if we deprecate
all the other non-deterministic 'CurrentXxx' properties.
Cheers,

Hi,
I agree with the proposal.
However, I strongly DISAGREE with the creation of new DefaultXxx
properties to be used in place of CurrentCharSet/NaturalLanguage.
We had this discussion during the development of IPP and concluded
that DefaultXxx has the wrong semantics, because they CANNOT be
overridden by the user. They are the character set and language
for the values in the Printer Description class of attributes (broadly,
everything except Status attributes). A specific user can request
a Notification (for example) in a different charset/language, but the
Printer current values don't change. This is NOT the semantics
of DefaultXxx on a Printer object.
Note that the user MUST specify the charset/language of submitted
string attributes with an IPP Job - it's a protocol error to omit them.
Cheers,
- Ira

Rick,
Makes sense. Perhaps we got carried away in our generalizations and missed
the distinction.
I would see no benefit in changing the names of urrentCharSet or
CurrentNaturalLanguage

Re: Deprecating (almost) all CurrentXxxx properties in CIM_Printer
Slight revision to the proposal: Deprecate all the CurrentXxxx properties
in favor of the corresponding DefaultXxxx properties, except CurrentCharSet
and CurrentNaturalLanguage.
These last two properties, CharSet and NaturalLanguage, record the character
set and natural language being used for management, not for printing. They
are properties of the printer controller, not properties of print jobs.
Since they are asynchronous with printing functions, they do not suffer from
the ambiguities of the other CurrentXxxx properties in complex printers.
Also, neither of these properties has a corresponding DefaultXxxx property.
Therefore these two properties must be retained.
Summary:
CurrentPaperType deprecate; use DefaultPaperType instead
CurrentLanguage deprecate; use DefaultLanguage
CurrentMimeType deprecate; use DefaultMimeType
CurrentCapabilities deprecate; use DefaultCapabilities
CurrentCharSet retain
CurrentNaturalLanguage retain
I recall that some exceptions were mentioned, but I think we all mistakenly
referred to CurrentLanguage instead of CurrentCharSet during the discussion.
Addendum to proposal: we could change the *names* of the two remaining
CurrentXxxx properties to DefaultCharSet and DefaultNaturalLanguage and then
be rid of all the CurrentXxxx properties. (Actual process: add new
properties with identical syntax and semantics but new names, and then
deprecate the old properties.) Only half kidding.
Comments, please.
