DIA WG colleagues:  In the telecon on Tuesday 4/9, we discussed my draft
Annex D for IPELTU.  For those that weren't there, my original action was to
develop an annex to instruct space operations teams what data should be
preserved.  I have expanded that to be an annex for spaceflight
programs/projects as a whole, on the premise that at the beginning of a
project we need for the top-level program/project manager to dictate to the
rest of the team what will or will not be preserved, from his mission, in
the long term.  So it's no longer just operations, it's the whole mission.
The checklist makes some pointed statements that should get the attention of
management, about what results of his project are worth preserving in the
long run.  In this way, it encourages early (pre-phase A?) planning and
recognition that resources should be allocated for preservation.  


I've coined the phrase DPOP (Digital Preservation Objectives Proforma)
Checklist.  After some discussion, we discarded similar terms to PICS- and
ICS-Proforma to avoid any implication of "compliance" guidance.  Some
discussion on "Proforma" is in the first page instructions.  The single word
version (proforma vs. pro forma) is used for compatibility with other CCSDS


While this one is for space missions, I envision other DPOP Checklists as
annexes for other types of endeavors.  Manufacturing, academia, oceaneering,
information technology development, etc.  CCSDS does space missions, but
other disciplines can be invited to create DPOP Checklists for their


So, this is a very rough draft.  Steve Hughes has agreed to try to expand
section 1.5 with the experience of PDS, but of course other contributors and
other comments are welcome.   


Here are a few notes:  

*         I think it's important to keep the first page instructions limited
to one page.  If it's too long, it won't be read or used.  It has to be
something a manager can pick up and start checking/revising quickly.  

*         For Level 0, 1 and 2 processing guidance, I used this website:
http://www.srl.caltech.edu/ACE/ASC/level1/dpl_def.htm  Of course, different
missions will have different terminology, so I reflected that in the
first-page instructions.  

*         My intention in the check boxes is that this should be made
available in Word format (perhaps from SANA) for managers to easily capture
and modify for their program.  

*         Two levels of detail are represented.  High level for the managers
that want only 10 or so items to check off, and let the lower level teams
interpret it.  Detailed level (just barely begun) for the managers that
understand what needs to be preserved, and want to manage the resources
needed to preserve it.  


For discussion online and at Mountain View.
