[Moims-dai] R: Draft message about OAIS

Mon Apr 17 08:24:02 UTC 2023

HI Roberta, Eld and Dawei

Yes we should mention the date – the linked document shows October 2020.

Yes we should make sure we cover all the appropriate lists – but avoid duplications. 

Please add name of list to http://review.oais.info/show_bug.cgi?id=351 before emailing – just to check whether someone else has already sent the message.

Subject: [Moims-dai] R: Draft message about OAIS

Hi David,

In my opinion the message you wrote is clear and polite, as we discussed in the last meeting. 

I agree with Dawei proposal to mention that the new ISO standard is based on the 2020 version of the document.

About the target of the message, I propose to review together the list during the tomorrow DAI WG call.

Kind Regards,

Roberta

News on OAIS and ISO

This message is to provide an update on the revision of OAIS. 

OAIS is edited within CCSDS, taking on board the widest possible range of suggested changes. What happened in the past is that it then goes through into the ISO review process immediately. Care has been taken to ensure that the CCSDS and ISO versions are identical. The ISO version in the past was simply the CCSDS version with an ISO cover sheet.

However, the new version of OAIS, which went through a long review process in CCSDS, has not yet gone into ISO. This is because the processes in ISO and between ISO and CCSDS changed. This has meant that the route to ISO has been stalled for the past year. The good news is that the issues with the CCSDS to ISO process have now been resolved.

The new CCSDS version of OAIS will go into ISO at the start of June. 

The reason for this slight delay from now to June is as follows.

The ISO processes have continued and the 2012 version of OAIS is undergoing its automatic periodic ISO review which ends in the first week of June. We must wait for that process to end before submitting the new CCSDS version through the ISO fast-track process. It would therefore make sense for people to comment on the new CCSDS version in order to avoid going through the changes resolved previously – details at http://review.oais.info <http://review.oais.info/> . 

The changed ISO processes mean that there may be some typesetting changes going through the ISO system, and of course there may be some changes arising from the ISO review itself. We will ensure that the published CCSDS and ISO versions have identical content.

The new CCSDS version of OAIS, which will go into ISO, is available at https://cwe.ccsds.org/moims/docs/MOIMS-DAI/Draft%20Documents/OAIS%20v3/650x0m3-A4.pdf and https://cwe.ccsds.org/moims/docs/MOIMS-DAI/Draft%20Documents/OAIS%20v3/650x0m3-A4.docx. These are in A4 page size rather than Letter, as required by ISO. Remember the document may change slightly through the ISO review.

Since this message is going to many email lists, if there are any questions on this, it would help if they are copied to the DAI mailing list, which may be joined at https://mailman.ccsds.org/cgi-bin/mailman/listinfo/moims-dai 

Regards
