Hi Mark

See my responses below. We should discuss these points over the next few days.

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

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?

Eld pointed out that there are many outside DAI are wondering what has happened to the OAIS update. Some are aware that there is an ISO review going on – but it is the 2012 version. So they are confused. 

2.	What lists will it be sent to?

Various email lists – we must co-ordinate to avoid duplications.

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 <http://review.oasis.info>  site or set up a separate list for comments?

I meant to provide a way for people to ask about the process – not comment on OAIS. They could just rely to whatever list they saw the message on. But that means monitoring many lists. Another option would have been to email me (david at giaretta.org <mailto:david at giaretta.org> ) – but that would put me in too privileged position.

So I came up with the DAI list – but that needs people to join the list – at least everyone would see the comments/questions.

I agree that comments on OAIS itself should be via review.oais.info    

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

This is what the process is called i.e. because CCSDS is a Class A liaison organisation, the document goes straight to DIS review.

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 above.

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.

Yes

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 <http://review.oais.info/> .

Yes, but for some reason we were not informed.

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 https://mailman.ccsds.org/cgi-bin/mailman/listinfo/moims-dai

My two cents,

Mark Conrad

At the last DAI meeting I took an action to draft a message which we could post on various email lists to explain what has been happening to OAIS.

Comments please.
