My understanding of what “understand” a musical recording is that I can play/use that recording. I think the same could be said of any type of “art”. What does it mean to understand an of (or an original) painting? And does that definition of understand change when you’re viewing a Rubens vs. a Fra Angelico vs. Van Gogh vs. a Picasso vs. a Rothko, etc?<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'>I would also disagree his discussion of copyrighted works that do not allow changes. I think MR#4 and OAIS Archives appropriately include and address them also. I think in many if not most cases you may not want to make changes to the original work even in the long-term. That does not mean that additional “metadata” can’t be added to address the need to continue to understand that item.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'>I definitely agree with Don that the Independently Understandable requirement exists not only at deposit time but is a continually evaluated requirement. <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'>One new view I’d add at this point. I think one problem is that in the updates we are emphasizing use by client systems too much. And we are viewing client systems as actors completely separated from the actual persons they are acting for. “Client system” is only used 4 times in OAIS in definition/text describing Consumers and Producers.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'>For example:<o:p></o:p></span></p><p class=MsoNormal><b>Producer</b>: The role played by those persons or client systems that provide the information to be preserved.

Access and use is certainly important for archives, but is not the primary focus of an OAIS. New tools can be developed to support access and use of information if it is preserved and understood, but the information will not be accessed if it isn’t there any more because it wasn’t preserved.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'>We can discuss this more at DAI webex later today. <o:p></o:p></span></p><p class=MsoNormal><a name="_MailEndCompose"><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'><o:p> </o:p></span></a></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'>Peace and joy,<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'>-JOhn<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'><o:p> </o:p></span></p><div><div style='border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'>From:</span></b><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'> MOIMS-DAI [mailto:moims-dai-bounces@mailman.ccsds.org] <b>On Behalf Of </b>D or C Sawyer<br><b>Sent:</b> Monday, August 7, 2017 3:18 AM<br><b>To:</b> MOIMS DAI List <moims-dai@mailman.ccsds.org><br><b>Subject:</b> Re: [Moims-dai] Suggested text for "Preservation Objectives" concept.<o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>All,<o:p></o:p></p><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>I’ve generated a short document that details my conclusions, both positive and negative, along with my analysis leading to my conclusions.
