[Moims-dai] Some updates to the message about OAIS, for discussion

How about this update to the message about OAIS. One problem is that it has
become rather long - despite Bob's warning.

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

This message is prompted by the fact that several people have been concerned
that ISO is conducting a review of OAIS which is based on the 2012 version
of OAIS, despite the fact that many people have contributed to a revision of
OAIS in the past few years. 

This message provides an update on the revision of OAIS and an explanation
of the current ISO review.

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 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 (dated Oct 2020), which went through a long
review process in CCSDS, has not yet gone into ISO. This is because the
processes within ISO and between ISO and CCSDS have 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 currently
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 (dates Oct 2020) 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%20v3/650x0
m3-A4.pdf. These are in A4 page size rather than Letter. This is required by
ISO. Remember the document may change slightly through the ISO review.
