In fact his response, and then Bruce’s response to David, have highlighted where the major disconnect lies. In short, I believe that David has a picture for the application of Provenance (and PDI more generally), that is at variance to the actual text and modeling contained in OAIS RM 2012. Therefore I find his view of the impact of SC222 is also at variance to the OAIS RM with SC222 incorporated. I’m providing a short description of the issue in the following text and 2 accompanying diagrams.<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>Bruce has made a valuable contribution pointing out the long standing use of Provenance in the Cultural Heritage community. Bruce was a valuable contributor to the development of the initial OAIS RM and therefore it is not surprising that we deliberately associated Provenance Information with the Content Information. The Content Information is the original target of preservation and it is this information, whether physically or digitally based, whose Provenance is of particular interest. This Content Information is the particular information that the OAIS is most concerned with preserving.<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>Here is the key point: there is all kinds of other information that an Archive will need to maintain, and much of it will likely be digital. We did NOT define Provenance to be associated with any of this other information. Specifically it is NOT defined with respect to a general Information Object, and appropriately so. (A proposal to define Content Information as any Information Object within the Archive was firmly rejected.) Real archives need to distinguish that information that is the original target of preservation from all other information because that information is treated differently in terms of the human effort and other resources applied. Thus Provenance is properly focused on the Content Information, and because Content Information is defined as a Content Data Object plus its Representation, Provenance can be applied to distinguish the possible different histories of these two components as appropriate. David’s statement that the OAIS is about the preservation of Information Objects, in general, is simply not true. This is clear from the Terminology section, the information modeling, and its associated text even with the incorporation of SC222 which focuses on the Content Data Object and NOT a general Data Object. There is no room for debate on this point.<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>David has pointed out, and appropriately so, that information other than Content Information needs to be maintained by the Archive. He prefers to use the term ‘preserved’, which is not incorrect, but this does not mean that it should get the same attention as the Content Information. It has been noted that Provenance Information will have some history and therefore its provenance may be of interest. This provenance is NOT our defined Provenance, even though the underlying concept for its usage is the same. The interest of an Archive in providing provenance on its Provenance, for example, is going to be much less than that on the original Provenance and it is very useful to have Provenance defined as it has been while requiring communicators to distinguish when they might mean provenance associated with other than Content Information or its components. <o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>I’m attaching 2 figures that summarize the PDI association reality. The first, consistent with OAIS RM 2012, gives an example Content Information object and its associated Provenance Information object. The various additional ways the Provenance Information might be associated are labeled A through F.<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>In the second figure, the result of incorporating SC222 is shown. It restricts the association to only the Content Data Object as given by the new definition of Provenance Information (and PDI generally). This may or may not be the intent of those supporting SC222, but it is the result.

These categories support preservation by documenting authenticity (Provenance, Fixity), identifying how the associated information is related to other information (Context) and thus improving understanding, identifying restrictions on usage (Rights) that may be in effect, and how information may be uniquely identified (Reference) in support of requests by Consumers. Content Information itself is composed of the Content Data Object (CDO) and its associated Representation Information (Rep.Info.). This high level PDI association concept says nothing about how PDI is to be associated with the Content Information components CDO and Rep.Info. It also says nothing about how this association might be implemented. The various PDI categories could be applied separately to the CDO and to the Rep. Info, as well as to the combination, as makes sense based on the nature of the CDO and the Rep.Info. In contrast, SC222 now restricts the PDI to only be associated with the CDO.<o:p></o:p></p></div></div></div><div style='margin-left:36.0pt'><div><div style='margin-left:36.0pt'><p class=MsoNormal> <o:p></o:p></p></div></div></div><div style='margin-left:36.0pt'><div><div style='margin-left:36.0pt'><p class=MsoNormal>I’ve seen only two arguments put forward in support of this major change.<o:p></o:p></p></div></div></div><div style='margin-left:36.0pt'><div><div style='margin-left:36.0pt'><p class=MsoNormal> <o:p></o:p></p></div></div></div><div style='margin-left:54.0pt'><div style='margin-left:36.0pt'><p class=MsoNormal>1.<span style='font-size:7.0pt;font-family:"Times New Roman",serif'> <span class=m-2105664666988286490apple-converted-space> </span></span>It is argued that it is virtually impossible to apply PDI to Rep.

The OAIS RM has attempted to be the ‘Gold Standard’ context for the discussion of preservation issues both at its founding and in the previous updates.This has led to the recognition of the need for improvements in implementation practices and subsequently to the ISO auditing effort.

If the OAIS RM is now going to be evolved to be more closely aligned with the detailed experience of auditors, it will logically take a narrower view of what is supported and not supported through its concepts. This will evolve with auditor experience and with technology changes and implementation practices. This OAIS RM could no longer be considered the conceptual ‘Gold Standard’ for the discussion of preservation issues. For example, the adoption SC222 has just removed a very valid preservation concept, the use of PDI in helping preserve Rep.Info., from the OAIS conceptual model. My view is that the preservation community needs to have a ‘Gold Standard’ reference model and PDI for Rep.Info. needs to be in it.<o:p></o:p></p></div></div></div><div><div><div style='margin-left:36.0pt'><p class=MsoNormal> <o:p></o:p></p></div></div></div><div><div><div style='margin-left:36.0pt'><p class=MsoNormal>Your understanding of what is being proposed is entirely wrong – see above.<o:p></o:p></p></div></div></div><div style='margin-left:36.0pt'><div><div style='margin-left:36.0pt'><p class=MsoNormal> <o:p></o:p></p></div></div></div><div style='margin-left:36.0pt'><div><div style='margin-left:36.0pt'><p class=MsoNormal>I believe that, lacking such a reference model, there may very well be competing models put forward, particularly in various disciplines, such as the library community, where there is already some concern that the OAIS RM is not always a good fit. One approach to this possibility is to clone an auditing version of OAIS that can evolve to better support the auditing while keeping a ‘Gold Standard’ OAIS that evolves more generally. Of course this would take resource that may not be available. Another approach is to take a rigorous approach to the separation of a ‘Gold Standard’ from the needs of auditing. If others have concerns along these lines, now would be a good time to speak up. However in the grand scheme of important issues, the future of the OAIS RM is not significant.<o:p></o:p></p></div></div></div><div style='margin-left:36.0pt'><div><div style='margin-left:36.0pt'><p class=MsoNormal> <o:p></o:p></p></div></div></div><div style='margin-left:36.0pt'><div><div style='margin-left:36.0pt'><p class=MsoNormal>C.

If I’ve counted correctly, through section 4.2 there were 33 reference to the CDO and now there are about 3 times as many (97). There were about 200 references to the Content Information and now there are about 138. This has put a greatly increased focus on the preservation of the Content Data Object, which for a digital archive is mostly a matter of preserving the bits. This is totally contrary to our past, successful, efforts to get the importance of the Representation Information more fully recognized. This has to be considered, at a minimum, ‘not helpful’ in this regard.<o:p></o:p></p></div></div></div><div style='margin-left:36.0pt'><div><div style='margin-left:36.0pt'><p class=MsoNormal> <o:p></o:p></p></div></div></div><div><div><div style='margin-left:36.0pt'><p class=MsoNormal>Your understanding of what is being proposed is entirely wrong – see above.<o:p></o:p></p></div></div></div><div><div><div style='margin-left:36.0pt'><p class=MsoNormal> <o:p></o:p></p></div></div></div><div style='margin-left:36.0pt'><div><div style='margin-left:36.0pt'><p class=MsoNormal>In addition, this change has complicated some relationships that show up in the new Terminology section.<o:p></o:p></p></div></div></div><div style='margin-left:36.0pt'><div><div style='margin-left:36.0pt'><p class=MsoNormal> <o:p></o:p></p></div></div></div><div style='margin-left:36.0pt'><div><div style='margin-left:36.0pt'><p class=MsoNormal>1.
