[Moims-dai] Draft message about OAIS

Sun Apr 16 20:03:53 UTC 2023

Hi David,

Thanks for putting this together. I have a few questions and then some
*comments* within the text.

1. Who is the target audience for this message?

2. What lists will it be sent to?

3. Do you really want people joining the DAI list just to comment on the
draft? Won't this make internal DAI conversations more difficult? Wouldn't
it be better to refer folks to the review.oasis.info site or set up a
separate list for comments?

4. What is the significance of the new version of OAIS going through the
ISO fast-track process?

5.If the primary audience for this message is folks who may want to comment
on the new draft, I am not sure how helpful all of the details about CCSDS
and ISO processes will be. Why not just issue a new call for comments on
the latest CCSDS draft?

See comments below:

News *on the Reference Model for an Open Archival Information System (OAIS)*
and the *International Organization for Standardization (ISO)*

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

OAIS is edited within *the Consultative Committee for Space Data Systems
(CCSDS),* taking on board the widest possible range of suggested changes.
What happened in the past *is that once CCSDS completes its editing the
document* 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 (*which was
renewed without change in 2017) *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.

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*. This is* *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

Regards

CCSDS DAI Working Group

My two cents,

Mark Conrad
