[IPP] Fwd: Question - IPP Job Ticket for 3D PDF's

[Ira McDonald via ipp <[e-mail]>]

Hi,

Please first look at Paul Tykodi's note and attachment below.

After discussion at this Monday's PWG Steering Committee call, we recorded
the following
resolution in the minutes:

PWG and Embeddable Job Tickets
- Discussion
  - Plan discussed was to create a "reference embeddable job ticket" and
put it on the FTP site, in
    some encoding

  - Opens up the issue of providing alternate encodings for IPP other than
"application/ipp"
    - How does our PJT work dovetail with this?

    - Figuring this out is a task for the IPP WG - Ira and Mike to consider
this

I do NOT propose to add this as a work item in the revised IPP WG Charter.
However, I *do*
encourage discussion in the IPP WG.

Comments?

Cheers,
- Ira

Subject: [SC] Question - IPP Job Ticket for 3D PDF's

Hi Mike,



The PDF Association recently published the attached release note covering
metadata stored within a PDF file. I participated in a short meeting with
Duff Johnson (PDF Association Executive Director) and Phil Spreier
(Technical Director 3D PDF Consortium – PDES) a few weeks ago and Duff
represented to me that he felt the attached document could provide PWG with
information it would need to insert a job ticket into a 3D PDF file.



The use case is that we imagine a future where Adobe possibly extends the
Adobe PDF Print Engine and creates a new APPE-3D version. The purpose is to
provide 3D printer manufacturers with a software component they can add
into their product so that their equipment can consume a 3D PDF and print
the 3D content without needing to transform the 3D content into an
alternative file format for internal processing.



If the use case was to then reliably deliver a 3D PDF file to a 3D printer,
using IPP semantics for job ticket but not necessarily the IPP protocol for
delivery, would the attached document actually help describe how to place
the job ticket semantics into the 3D PDF file itself?



Also do you have any opinions about whether this would be a good idea or
not?



Thanks.



Best Regards,



/Paul
