<div style="FONT-FAMILY: Arial; COLOR: #000000; FONT-SIZE: 12px"><div>Don,</div><div>Thank you for that succinct and logical statement As one of the principal authors of OAIS your views carry a lot of import for me. Their approach may be the "flavor of the month," but their approach goes beyond the conceptual to a specific implementation. As you note OAIS is a conceptual model not implementation specifications. I hope there will be support for returning informative annexes. This could be one as an approach to what OAIS calls federated archives.</div><div> </div><div> </div><div style="border-top:1px solid #bcbcbc;margin:5px 0px;"></div><span style="font-size:12;font-family:arial;color:#000000;">On 02/15/17, <span>D or C Sawyer<Sawyer@acm.org></span> wrote:</span><div> </div><div style="font-size:12;font-family:arial;color:#000000;">All,<div><br /></div><div>I have a few initial thoughts on SC#135. It is clearly a special case. The vast majority of current archives are not distributed in the sense of relying on cooperating, independently funded, organizations to ensure long term preservation of some particular information. However one can consider farming out some archival services, such as storage to the ‘cloud’ (Dropbox?), and then ask the question ‘do we still have an OAIS archive’? OAIS is a conceptual model intended to provide terms and concepts to describe what is needed and to talk about implementations. It still works in such a situation but it prompts the question as to whether such implementations are sufficiently reliable, given the independent funding. I think the short answer is ‘it depends’. As far as the concept of an OAIS within an OAIS goes, I don’t think it makes any sense. If the inside implementation is a full OAIS, then what is the outside OAIS adding? If it has additional information, then what one has is really two coordinating or cooperating OAISs.</div><div><br /></div><div>I would be totally opposed to making OAIS any more complex than it is. However these issues of distribution and the reliability of independently funded services are important. I could see an informational annex, as John has suggested, provided there is time to get a consensus on what it should say. I would suggest it be short, again lay out the purpose of OAIS, note its applicability to distributed implementations (already in OAIS), and then specifically note the issue of relying on independently funded organizations for some critical archival internal functions or services. As David has noted, this seems particularly relevant to ISO 16363. It might be appropriate to note, in such an Annex, that users of such an archive should be made aware that the archive is relying on the services of an independently funded organization or implementation for part of the preservation function. </div><div><br /></div><div>My initial thoughts.</div><div><br /></div><div>Cheers-</div><div>Don</div><div><br /></div><div><br /></div><div><br /></div><div><br /><div><div>On Feb 15, 2017, at 7:16 AM, David Giaretta <<a class="parsedEmail" href="mailto:david@giaretta.org" target="_blank">david@giaretta.org</a>> wrote:</div><br class="Apple-interchange-newline" /><blockquote type="cite"><div lang="EN-GB" link="#0563C1" style="font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px;" vlink="#954F72"><div class="WordSection1" style="page: WordSection1;"><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;"><b><span style="font-size: 14pt;">Notes from DAI Webex meeting 2017-Feb-14</span></b></div><ol start="1" style="margin-bottom: 0cm;" type="1"><li class="MsoNormal" style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;"><span style="font-size: 12pt;">Status of Report to CMC on status of DAI WG Future - version sent was<a href="https://www.dropbox.com/s/qwkehdgcq0ur5sk/MOIMS-DAI%20WG%20Report%20to%20the%20CMC.pdf?dl=0" style="color: rgb(149, 79, 114); text-decoration: underline;" target="_blank">https://www.dropbox.com/s/qwkehdgcq0ur5sk/MOIMS-DAI%20WG%20Report%20to%20the%20CMC.pdf?dl=0<span style="color: blue; text-decoration: none;"><span><image003.png></span></span></a><span class="Apple-converted-space"> </span>– Word version is<a href="https://www.dropbox.com/s/lztl9n18sbyvnrt/MOIMS-DAI%20WG%20Report%20to%20the%20CMC%20MOIMS-MM-BB-comments-DAI-responses-v4.docx?dl=0" style="color: rgb(149, 79, 114); text-decoration: underline;" target="_blank">https://www.dropbox.com/s/lztl9n18sbyvnrt/MOIMS-DAI%20WG%20Report%20to%20the%20CMC%20MOIMS-MM-BB-comments-DAI-responses-v4.docx?dl=0<span style="color: blue; text-decoration: none;"><span><image003.png></span></span></a></span></li><ul style="margin-bottom: 0cm;" type="circle"><li class="MsoNormal" style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;"><span style="font-size: 12pt;">Webex held with Mario on Monday 13th Feb</span></li><li class="MsoNormal" style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;"><span style="font-size: 12pt;">DG will send around notes on the meeting.

OAIS already deals with distribution. Mentioned at iPres and other meetings as a need. This is a valid area of work but it may need more work before it could be incorporated into the OAIS. The OAIS does not specify a distribution architecture nor does it prohibit it. Check all references to distributed in the current standard and make sure they do not impede distributed services. Sections 6.1.1 through 6.1.4. Add another example/instance - Distributed OAIS functional entities are distributed but form one OAIS.
