This has been there from the beginning to make clear it is referring to the original information provided by the Producer and not just any information within the Archive. This is important to ensure that when people are discussing preservation within an OAIS context, everyone understands this is the information originally provided by the Producer. </div><div class=""><br class=""></div><div class="">Of course we understand why you want to make this change because you still want to move Content Information to being ANY information in the Archive so you can claim the whole process is recursive by definition ‘and been there from the beginning'. This would be a radical, ambiguity enhancing, change to the long standing common understanding of the OAIS information and functional modeling. For these reasons this proposed change should be thoroughly rejected by the group.</div><div class=""><br class=""></div><div class="">Cheers-</div><div class="">Don</div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><div><br class=""><blockquote type="cite" class=""><div class="">On Apr 2, 2019, at 10:06 AM, David Giaretta <<a href="mailto:david@giaretta.org" class="">david@giaretta.org</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div class="WordSection1" style="page: WordSection1; caret-color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration: none;"><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class=""><o:p class=""> </o:p></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class=""><o:p class=""> </o:p></div><div class=""><div style="border-style: solid none none; border-top-width: 1pt; border-top-color: rgb(225, 225, 225); padding: 3pt 0cm 0cm;" class=""><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class=""><b class=""><span lang="EN-US" class="">From:</span></b><span lang="EN-US" class=""><span class="Apple-converted-space"> </span>David Giaretta <<a href="mailto:david@giaretta.org" style="color: rgb(149, 79, 114); text-decoration: underline;" class="">david@giaretta.org</a>><span class="Apple-converted-space"> </span><br class=""><b class="">Sent:</b><span class="Apple-converted-space"> </span>02 April 2019 13:12<br class=""><b class="">To:</b><span class="Apple-converted-space"> </span>'Mark Conrad' <<a href="mailto:mark.conrad@nara.gov" style="color: rgb(149, 79, 114); text-decoration: underline;" class="">mark.conrad@nara.gov</a>>; 'John Garrett' <<a href="mailto:garrett@his.com" style="color: rgb(149, 79, 114); text-decoration: underline;" class="">garrett@his.com</a>><br class=""><b class="">Subject:</b><span class="Apple-converted-space"> </span>CDO text<o:p class=""></o:p></span></div></div></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class=""><o:p class=""> </o:p></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class="">My suggestions for the additional text:<o:p class=""></o:p></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class=""><o:p class=""> </o:p></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class="">Change in current draft from:<o:p class=""></o:p></div><div style="margin: 0cm 0cm 0.0001pt 18pt; font-size: 11pt; font-family: Calibri, sans-serif;" class=""><b class="">Preservation Description Information (PDI</b>): The<b class=""><span class="Apple-converted-space"> </span></b>information, which along with Representation Information, is necessary for adequate preservation of the Content Data Object and which can be categorized as Provenance Information, Context Information, Reference Information, Fixity Information, and Access Rights Information.<o:p class=""></o:p></div><div style="margin: 0cm 0cm 0.0001pt 36pt; font-size: 11pt; font-family: Calibri, sans-serif;" class="">Note: Defining PDI (as well as its components - Provenance Information, Context Information, Reference Information, Fixity Information, and Access Rights Information) as relevant to the Content Data Object does not mean that those concerns are any less important for other data objects or at other levels, for example, it is important to apply reference, fixity, provenance, context and access rights to Representation Information, or to any other information the Archive is preserving.
