<p class="MsoNormal" style="margin-left:.5in"> <o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in">Thank you for agreeing, although reluctantly, to forward the OAIS document to CMC leading to formal agency review.<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in">I’m providing a few clarifications that hopefully will ease your reluctance.<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in"> <o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in">Yes I can confirm that DAI has accepted your other suggested changes.

<p class="MsoNormal" style="margin-left:.5in"> <o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in">The only point of contention is the definition of an OAIS. I think the issue is that as a Magenta Book, OAIS provides
<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in;text-indent:.5in">“normative, controlling guidance rather than purely descriptive material” (CCSDS A02.1-Y-4)<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in">and so it is not simply describing an IT system. Thanks to your other comments we have made the normative parts of the document much clearer.<o:p></o:p></p>

<![if !supportLists]><span style="font-family:"Courier New""><span style="mso-list:Ignore">o<span style="font:7.0pt "Times New Roman"">
</span></span></span><![endif]>But OAIS, as a Magenta Book, provides normative controlling guidance, and is not just a description of an IT system. The policies and procedures could be viewed as the equivalent of the software of an IT system.<o:p></o:p></p>

<![if !supportLists]><span style="font-family:"Courier New""><span style="mso-list:Ignore">o<span style="font:7.0pt "Times New Roman"">
</span></span></span><![endif]>But the system needs information (as a raw material) to help to decide what to do with the information it is storing, transferring, manipulating etc. This is surely true of all systems, whether that information is in database
tables or configuration files etc – which are clearly separate from hardware and software. I will edit the Wikipedia definitions to include this.<o:p></o:p></p>

</span></span></span><![endif]>But there are different types of systems and in particular not all systems are purely IT systems. We are defining an OAIS. Wikipedia defines many types of systems and we can easily add to that list. Of course there is already
a Wikipedia article about OAIS which uses the current definition. We can update this in due course so that Wikipedia continues to be accurate.<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in"> <o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in">We can eliminate the Wikipedia definition you propose of an information and computer science system since OAIS is not just an IT system.<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in">The third definition you provide, from CCSDS 910.2-G-1, is for what is termed a “real system”, rather than a general definition. That GB does not provide a general definition of system.
<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in"> <o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in">The second definition, which originated in one of your SEA documents, is much closer to what we intended. I believe that our definition comes very close to that definition as can be seen in the analysis below,
comparing to the proposed definition of an OAIS which is below the table:<o:p></o:p></p>

<p class="MsoNormal" style="margin-left:1.0in">Dear David, et al,<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:1.0in"> <o:p></o:p></p>
<p class="MsoNormal" style="margin-left:1.0in">I'd like to thank you and your team for taking my suggestions seriously and for working diligently to improve the clarity of the document. I am really glad that you took this opportunity to make these long overdue
changes. I suspect that your community will also appreciate the changes.<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:1.0in"> <o:p></o:p></p>
<p class="MsoNormal" style="margin-left:1.0in">I have read the document (a quick skim this time), and find that I agree with all of the changes that you have made. The added clarity in use of terms and diagrams helps a lot. I did find a few relatively minor
items that I still wish to ask that you fix. Instead of doing the usual "change this to that" PID format I just made the proposed changes directly in the text, which I have attached with Track Changes turned on. For transparency, I will tell you where to
look:<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:1.0in"> <o:p></o:p></p>
<p class="MsoNormal" style="margin-left:1.0in">Sec 1.1: fixed the definition of an OAIS to align with the usual notion of what a "system" is:<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:1.0in"> <o:p></o:p></p>
<p class="MsoNormal" style="margin-left:1.5in"><span style="color:#0070C0">An OAIS is an Archive system consisting of hardware, software, and procedures developed and operated by an organization. The organization has accepted the responsibility to preserve
information and make it available for a <b>Designated Community</b>. The organization may be part of a larger organization.</span><o:p></o:p></p>
<p class="MsoNormal" style="margin-left:1.0in"> <o:p></o:p></p>
<p class="MsoNormal" style="margin-left:1.0in">Made the same change in sec 1.6.2 Terminology.<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:1.0in"> <o:p></o:p></p>
<p class="MsoNormal" style="margin-left:1.0in">In other sections and sub-sections I added a clarifying sentences in the intro paragraphs, of the general form: "This sub-section (<u>or this entire section</u>) is non-normative.". I am concerned that without
this sort of clarity the mix of normative and non-normative materials in various sections can cause confusion. I did not want it to be too intrusive, but I think we must be clear.
<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:1.0in"> <o:p></o:p></p>
<p class="MsoNormal" style="margin-left:1.0in">To take the "sting" out of this, in some sections I added an explanatory sentence, like this one in Sec 4.2:<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:1.0in"> <o:p></o:p></p>
<p class="MsoNormal" style="margin-left:1.5in"><span style="color:#0070C0">This entire subsection is informative, but provides useful abstractions for understanding how an OAIS might be designed.</span><o:p></o:p></p>
<p class="MsoNormal" style="margin-left:1.0in"> <o:p></o:p></p>
<p class="MsoNormal" style="margin-left:1.0in">I hope that you and your team can accept these changes. If the answer is yes you have my concurrence to go forward.<o:p></o:p></p>

<p class="MsoNormal" style="margin-left:1.5in">Dear Peter<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:1.5in"> <o:p></o:p></p>
<p class="MsoNormal" style="margin-left:1.5in">Steve Hughes provided us with feedback following your discussion with him. As a result we have taken an in-depth look at the conformance sections, the definitions and discussion of Representation Information, and
in particular “Semantic Information”, and the discussion of Representation Information Networks. I believe we have made significant improvements to OAIS as a result. Some of the text dates back to the original version of OAIS; it is only thanks to your insistence
that we were forced to recognize a number of weaknesses and sources of confusion for readers.<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:1.5in"> <o:p></o:p></p>
<p class="MsoNormal" style="margin-left:1.5in">The updated document is available at

<p class="MsoNormal" style="margin-left:1.5in"> <o:p></o:p></p>
<p class="MsoNormal" style="margin-left:1.5in">A short list of the changes are:<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:2.0in;text-indent:-.25in;mso-list:l1 level1 lfo5">
<![if !supportLists]><span style="mso-list:Ignore">-<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>The conformance section 1.4 has been clarified as you suggested and the individual sections are clearly marked as “normative”<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:2.0in;text-indent:-.25in;mso-list:l1 level1 lfo5">
<![if !supportLists]><span style="mso-list:Ignore">-<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>We checked the use of shall/must. One instance of “must” was missing from a section marked as normative. We found we did have some uses of “must” in informative sections, which we re-phrased.
<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:2.0in;text-indent:-.25in;mso-list:l1 level1 lfo5">
<![if !supportLists]><span style="mso-list:Ignore">-<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>Changed the name of Semantic Information to “Semantic Representation Information” to avoid confusion with Semantic networks etc. The definition has been clarified to
<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:2.5in;text-indent:-.25in;mso-list:l1 level2 lfo5">
<![if !supportLists]><span style="font-family:"Courier New""><span style="mso-list:Ignore">o<span style="font:7.0pt "Times New Roman"">
</span></span></span><![endif]>“Semantic Representation Information: The Representation Information that further describes the meaning of the Data Object, and its parts or elements, beyond that provided by the Structure Representation Information.”<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:2.0in;text-indent:-.25in;mso-list:l1 level1 lfo5">
<![if !supportLists]><span style="mso-list:Ignore">-<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>There is a similar change for Structure Information to “Structure Representation Information”, which is now defined as
<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:2.5in;text-indent:-.25in;mso-list:l1 level2 lfo5">
<![if !supportLists]><span style="font-family:"Courier New""><span style="mso-list:Ignore">o<span style="font:7.0pt "Times New Roman"">
</span></span></span><![endif]>“Structure Representation Information: The Representation Information that imparts information about the arrangement of and the organization of the parts or elements of the Data Object”<o:p></o:p></p>
<p class="MsoNormal" style="margin-left:2.0in;text-indent:-.25in;mso-list:l1 level1 lfo5">
<![if !supportLists]><span style="mso-list:Ignore">-<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>The explanation of Representation Information Networks has been updated, with some new diagrams which we hope make the concept very clear.

<p class="MsoNormal" style="margin-left:1.5in">We hope that clears the way for progressing OAIS to the next stage.<o:p></o:p></p>
