I have not heard anyone disagree that, under some circumstances, a physical book does not need RepInfo. As an example, I believe an Archive implemented primarily for the preservation of physical books (Content Data Objects) understandable to the associated Designated Community would be fully justified in not conjuring up information, to be called RepInfo, just to meet someone’s concept of a best practice or a mandatory requirement for some type of certification. There may, or may not, eventually be a requirement for the addition of real RepInfo to such CDOs. This is all about practical implementations. <o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>In contrast, the OAIS RM is a conceptual model and its AIP is the key unit of information that is being preserved. The AIP is defined to include RepInfo with the CDO, forming Content Information, as this Content Information entity is of central importance to the preservation of digital information. I see no reason to alter this Content Information definition and I don’t believe anyone is proposing to do so. At the same time I have no problem recognizing that some implementations, such as that given in the Archive example above, may have an AIP whose Content Information is the CDO alone. This simply reflects local, practical, reality. The example highlights the possible differences between a concept and local reality. In my opinion, when there is good justification, such differences should not be of major concern. David’s proposal for the OAIS RM regarding implicit and explicit RepInfo is designed to acknowledge this reality. While I had some objection to the ‘implicit’ part of his proposed wordingl, I firmly support the attempt and believe some appropriate words can be found. It should not take a lot of discussion to find such words if there is agreement on the objective.<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>When the OAIS RM uses the phrase ‘Representation Information’, it should mean the same concept everywhere in the document. It should not also stand for some made up sentence just to satisfy a conceptual information category. Therefore I think John’s second paragraph below is properly understood as an implementation view where he thinks an actual AIP should always have a RepInfo category. One could consider this a possible best practice, but personally I would not go that far. Discussion of this particular view makes sense in the context of ISO 16363. As for the OAIS RM, again I support David’s attempt to clarify that some AIP implementations may not need explicit RepInfo <u>as it has been defined in the OAIS RM.</u> <o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>Cheers-<o:p></o:p></p><div><p class=MsoNormal>Don<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal><br><br><o:p></o:p></p><blockquote style='margin-top:5.0pt;margin-bottom:5.0pt'><div><p class=MsoNormal>On Jul 17, 2018, at 4:11 AM, John Garrett <<a href="mailto:garrett@his.com">garrett@his.com</a>> wrote:<o:p></o:p></p></div><p class=MsoNormal><o:p> </o:p></p><div><div><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'>Hi,</span><o:p></o:p></p></div><div><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'> </span><o:p></o:p></p></div><div><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'>I’m also uncomfortable with the updated conformance.

In other words, if the Data Object is a piece of paper written in English, and members of the Designated Community can read and understand English then there is no need for an explicit English dictionary because the Designated Community's Knowledge Base includes that.<span class=apple-converted-space> </span></span><o:p></o:p></p></div></div><div style='margin-left:.5in'><div><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'>><span class=apple-converted-space> </span></span><o:p></o:p></p></div></div><div style='margin-left:.5in'><div><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'>> However, if the Designated Community were to be defined as readers of Chinese then Representation Information such as an English Dictionary would be needed.

As far as I can see this would make the model complete and consistent. We could add some wording to the discussion of Representation Information and Designated Community to make this clear.</span><o:p></o:p></p></div></div><div style='margin-left:.5in'><div><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'>><span class=apple-converted-space> </span></span><o:p></o:p></p></div></div><div style='margin-left:.5in'><div><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'>> In terms of the idea of OAIS being only a "communications framework" - yes it is that, especially the Functional Model, but it also provides something more, namely guidance of what one needs in order to preserve digitally encoded information, and OAIS lays these out in terms of conformance. Thus, the repository needs an AIP with all its components; it needs to undertake all the Mandatory Responsibilities.<span class=apple-converted-space> </span></span><o:p></o:p></p></div></div><div style='margin-left:.5in'><div><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'> </span><o:p></o:p></p></div></div><div style='margin-left:.5in'><div><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'>Yes on the Mandatory Responsibilities, but on the ‘AIP with all its components’ there is considerable ambiguity. The information modeling conformance only addressed the Information Object and the Information Package as given in Section 2.2. The Information Package is broken into SIPs, AIPs, and DIPs, It is clear that SIPs and DIPs may not contain all the Representation Information or PDI. The implication (not stated) is that the AIP does contain all the Representation Information and PDI. Certainly it does conceptually. However the conformance section (1.4) addresses an actual Archive. The example above raises the conformance issue for an Archive that only preserves hardcopy documents, with no Representation Information, yet still fully understandable to its Designated Community, Maybe it also finds it doesn’t need all the PDI. Can it still claim to be OAIS conformant? I would say ‘yes’ as long as it is making a reasonable argument for not having all the components of the section 2.2 information models. Note also that none of the modeling in section 4.2 is required for OAIS RM conformance. Given that OAIS RM conformance has sometime been a topic of concern to others as well as to this working group, I recommend it be clarified.</span><o:p></o:p></p></div></div><div style='margin-left:.5in'><div><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'> </span><o:p></o:p></p></div></div><div><div><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'>I agree – we should make it clear that 2.2 and 4.2 are both included in the Mandatory Responsibilities and also in the Conformance section.
