I'm fine with "chosen" vs. "actual"... not as concerned about the name as
the concept. In this case, actual might differ from requested due to
something like a PDL override (so "chosen" seems to fit) or it COULD
differ due to some circumstance (like the job was aborted prior to all
copies completing) in which case "actual" seems more apropos.

Subject: RE: SM> Job "Actual" attributes
Hi Harry,
For what it's worth...
Printer MIB used (from DPA I think...) the terminology of
'Declared' or 'Requested' (for the input) and 'Chosen'
(for what you're calling 'Actual' below).
Cheers,

Subject: SM> Job "Actual" attributes
In IPP, PWG Semantic Model and PSI we have Job Template attributes with
"sister" (supported, default and ready) Printer Description attributes.
When
discussing the purpose of a "Job Ticket" in the semantic model, we often
refer to Job Template attributes as the "job ticket" as these carry
production intent. By definition, when queried, Job Template attributes
must
return the value associated with each attribute during submission. Thus,
there is no way to query a job (or document) and learn WHAT ACTUALLY
HAPPENED w.r.t. any particular attributed (ex. copies). This is covered by
the JDF job ticket but we have said JDF is too workflow oriented for
(initial) inclusion into the PWG Semantic Model.
I would like to propose a solution - the addition of a group of Job
Description attributes referred to as "-actual". These could be extensions
to the group of Job Progress attributes or a separate grouping of Job
Actual
(or "Job Completion") attributes. I know, in IPP proper, we don't have the
notion of job "history" (the job "disappears" as soon as it has completed)
so "actuals" would not be very useful. But in the semantic model and PSI
we're trying to overcome this. To the extent that we are reluctant to
embrace a full fledged job ticket, the addition of "-actual" attributes
should go a long way toward providing much of the essential JT
functionality
that was previously missing for non-produciton environments.
For example:
+===================+======================+
| Job Template |Job Description:Actual|
| Attribute | Value Attribute |
+===================+======================+
| copies | copies-actual |
| (integer (1:MAX)) | (integer (1:MAX)) |
+-------------------+----------------------+
| finishings | finishings-actual |
|(1setOf type2 enum)|(1setOf type2 enum) |
+-------------------+----------------------+
| sides | sides-actual |
| (type2 keyword) | (type2 keyword) |
+-------------------+----------------------+
| number-up | number-up-actual |
| (integer (1:MAX)) | (integer (1:MAX)) |
+-------------------+----------------------+
| orientation- |orientation-requested-|
| requested | actual |
| (type2 enum) | (type2 enum) |
+-------------------+----------------------+
| media | media-actual |
| (type3 keyword | | (type3 keyword | |
| name) | name) |
+-------------------+----------------------+
| printer-resolution| printer-resolution- |
| (resolution) | actual |
| | (resolution) |
+-------------------+----------------------+
| print-quality | print-quality-actual |
| (type2 enum) | (type2 enum) |
+-------------------+----------------------+
