Subject: Re: IPP> "-actual" containment issue
Peter,
Some thoughts:
1) In IPP, I was thinking it would be best if the "-actual" attributes are
simply "normal" Job Description attributes. Then they can be queried in
the same way, and follow the same conventions, as any other Job Description
attributes.
<PZ> I would think that we would want to allocate a new group tag for the
encoding as well as defining a new attribute group tag for requesting these
new attributes. Putting them all into a group simplifies the processing
since the entire unsupported group is ignored.<PZ/>
In the Semantic Model, you are proposing that they should instead be a new
group: that seems to make sense in the Semantic Model. However, I think I
would have preferred, at least initially, that the JobProcessingActual
elements *act* the same as the JobDescription elements, and the
DocumentProcessingActual elements act the same as the DocumentDescription
elements. In that case, JobProcessingActual would go under Job and
DocumentProcessingActual would go under Document.
<PZ> I don't see the downside of supporting a new group of attributes in
IPP as a proper attribute group. New implementations support the group
while old implementation ignore the entire group. It allows access to
individual members as well as the entire group.<PZ/>
2) If we *did* go with your idea, what is the advantage to putting
"JobProcessingActual" and "DocumentProcessingActual" under a
"ProcessingActual" entry, rather than just putting them directly under Job?
<PZ> The main advantage I see is that the whole job history would stand
on its own. Defined this way it would be possible to deal with "-actual"
data whether it came from a request on a Job object or through a separate
Job History interface offered by the Printer. <PZ/>

Dennis,
Attached is a diagram showing how the "-actual" objects could be
structured.
It puts the "ProcessingActual" elements in the Job. The "ProcessingActual"
contains "JobProcessingActual" and a multivalued
"DocumentProcessingActual".
"ProcessingActual" identifies its Printer and Job. Since there can be
multiple Documents, the "DocumentProcessingActual" identifies its
associated
Document.
Since the Job is the active entity is it appropriate to carry the Job
"Receipt"(i.e. "-actual") information there?

Dennis,
I believe that new groups should be created for "-actual" just as there are
groups for "supported" and "default". The "DocumentProcessingActual" group
should exist in both the Job and Document. The "JobProcessingActual"
should
exist only in the Job. This would parallel the processing elements nicely.
