Hi all

I am a bit concerned that the suggestion from Mark below can be read as putting this paper into the discussion tomorrow. I do of course not mind anyone reading the paper, but I see no reason for use of valuable time on OAIS meetings by start of a discussion of how a 2014 paper can be read/interpreted for the following reasons:

               JGG: I agree.  No reason we need to discuss the paper during tomorrow’s telecon.

*        There is nothing in the current text that suggests that it is only bit preservation, - the text taken out was part of an example

JGG: Great.  I’m glad that we can leave that out of the example.  I think it is better example if the inner OAISes do more than bit preservation.

*        The paper will not be referred to directly by the OAIS reference model, since I believe it is an error that the references are still in the draft (as said in my previous mail)
(as I recall, it was decided that these should be excluded from the document itself - and only will be referred to as “Further and more detailed examples can be found in [D13] and [D14]” in some surrounding documentation as for the roadmap section)

JGG:  OK.  I’ll eliminate it from Section 6 text.  It can be included in the website that will include the roadmap and OAIS relationships to other standards/efforts.

Not to start/continue the discussion here, but let me as author/coauthor of the referred documents point out that the message meant to be expressed is: that it is useful for bit preservation but NOT only for bit preservation. The OO-IO model is based on the IR-BR model which covers bit preservation – but the OO-IO model is a result of the international research project (described in the papers) which found that there was a need for a more general approach covering other areas as well.

               JGG: Good to have the context.

Best regards, Eld

" I also removed some of the discussion of Inner OAIS only need to worry about bit preservation.  Overall encouraging the idea that any OAIS only needs to worry about bit preservation is contrary to what we are trying to do with the OAIS standard.  Too many “archives” already take that view." 

Discussions of bit repositories and bit preservation are found throughout the OO-IO paper. I believe that, along with the varying definitions/examples of inner OAISes throughout the OO-IO document, are compelling reasons why we should not mention OO-IO in ISO 14721. If you haven't read it recently, I encourage you to read the OO-IO document before our discussion on Tuesday.

Hi,

I’ve attached my latest attempt for obtaining consensus for Section 6.

We will discuss this at the next MOIMS-DAI telecon on Tuesday.  If you are interested in this topic and if possible, please plan to join us that day.  Also if possible you can send comments and suggested updates before the telecon.

This is the last outstanding Suggested Change for this round of OAIS update.  Once completed, we will generate a complete new draft to send around for Working Group review and comment and then submit for balloting by CCSDS and ISO.  

The face-to-face meeting for our Working Group at the CCSDS technical meeting is just over a week away and we would like to discuss the final draft during that meeting.

In this version of Section 6, I’ve added back another of the Outer OAIS – Inner OAIS examples.  The examples appear as an example of the general Distributed Archive style discussed in Section 6.1.6.  I also removed some of the discussion of Inner OAIS only need to worry about bit preservation.  Overall encouraging the idea that any OAIS only needs to worry about bit preservation is contrary to what we are trying to do with the OAIS standard.  Too many “archives” already take that view.  Also, I’ve moved OAIS Section 6.2 Management issues for Federated Archives to the end of Section 6.1.3 Federated Archives

Peace and joy,
