the entire purpose of this document from an archival perspective. A few of the key sentences expressing the intent of the authors - going back to the first version of the OAIS - are: "For example, archival science focuses on preservation of the ‘record’. This term is not used in the OAIS Reference Model, but one mapping might approximately equate it with ‘Content Information<o:p></o:p></p></div><div><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'>within an Archival Information Package’ (see definitions below, as well as 2.2 and 4.2 for context)."

One main objection I keep hearing is that the change implies that an Archive can no longer preserve RepInfo. The change is just that the target of the PDI term was proposed to be updated to be the CDO instead of Content Information. Defining PDI as applying to Content Information did not mean that Fixity Information or Provenance Information did not need to be preserved as a normal course of action. Defining PDI as applying to CDO does NOT mean that RepInfo does not need to be preserved.</span><o:p></o:p></p></div></div></div></div></div></div></div></div></div></div></div></blockquote><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal><span style='color:#9900FF'>MC: I believe you are missing the point. From an archival perspective you cannot preserve the original target of preservation (i.e., the Content Information) without preserving the CDO <b>and</b> the RepInfo. In order to preserve the RepInfo <b>you must have PDI for the RepInfo in addition to the PDI for the CDO.</b> You need to preserve the RepInfo to make the CDO understandable. Otherwise you would just have a string of bits with no way of interpreting them. To preserve the RepInfo you need evidence that the RepInfo is the correct RepInfo for understanding the CDO and that the RepInfo has not been tampered with since it was Ingested. To do these things you need PDI for the RepInfo in addition to the PDI for the CDO.</span><o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><span style='color:red'>JGG: I think I understand your point specifically that you cannot preserve the information that is intended to be preserved without preserving both the CDO and the associated RepInfo (and also the information that says they’re associated).<o:p></o:p></span></p><p class=MsoNormal><span style='color:red'>You also need to preserve other things to preserve the information intended to be preserved.

The CDO is the source of why the RepInfo is created/supplied. I would strive to preserve the CDO even if I lost part (or even all) the RepInfo with the hope that I could at some point rediscover the RepInfo. Conversely, I would not have much desire to continue to preserve RepInfo if I lost the CDO.
