<p>Mario,</p>
<p>DAI has reviewed my note, and agreed that we (DAI) will work
together to produce the presentation pages and I should have
something for you by COB next week. <br>

<p>I was invited to participate in one of the MOIMS-SM&C
sessions at this week's CCSDS meetings in Gaithersburg,
Maryland. My role was to represent the DAI (Digital Archives -
Ingest) in a discussion of long term preservation of data assets
(including plans, products, and ancillary artifacts) anticipated
for future planned missions, segments and systems.<br>
</p>
<p>Initially, My understanding of some of the issues being
discussed had been informed by Mario Merri's presentation to the
MOIMS plenary on Monday. Even with that, it was unclear what I
was going to offer to the attendees, as I was unfamiliar with
the SM&C terms of reference, workplans or meeting agenda. <br>
</p>
<p>The group was able to fairly quickly give me enough of an
understanding of the issues they would like DAI to address for
SM&C and MOIMS in general. Specifically, they would like
us to supply arguments supporting the need for (and value of)
longterm preservation and concomitant longterm availability of
data assets. Once established, such requirements could be used
as leverage to support functions like data asset management to
protect the viability of that data for use in an information and
knowledge management function that could range beyond the
purview of individual missions. <br>
</p>
<p>Some ideas (expressed or implied) from the session:</p>
<ul>
<li>We (DAI) need to create a very high level view of the value
and costs of long term preservation that can be used in
Executive sessions. Even though we're some ways from having a
distributable draft of the IPELTU document, several important
ideas should be expressible by themselves to help explain how
much (or how little) preservation related information missions
would need to collect and save to support transfer to a TDR.
<br>
I hope to have some (no more than a handful of) charts
introducing appropriate IPELTU and OAIS concepts to send to
Mario Merri within the next two weeks. I've sent a request to
Mario Merri for a copy of his MOIMS Plenary charts as a
starting point for these. </li>
<li>DAI might find it advantageous to augment the IPELTU effort
with a checklist that can be used in the early stages of a
project to identify areas to be addressed by engineering
studies in support of Long Term Preservation<br>
</li>
<li>To add to the arguments for at least executing engineering
studies to size the effort to support long term digital
repositories of space mission data, we should summarize known
failures (and their consequences) to preserve data.<br>
</li>
<li>The distinction between long term (ie, preservation)
archives and local (segment,system, or mission) archives
should be analyzed to document the differences and
equivalencies between them. MOIMS hopes to be able to produce
a White Paper within the next two months discussing needs for
Mission Ops standards and this topic might be addressed in
that paper.</li>
</ul>
<p>That's all for now. See you on Wednesday.</p>
