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.<o:p></o:p></span></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span lang=EN-US>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.</span><o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span lang=EN-US>The new CCSDS version of OAIS will go into ISO at the start of June.</span><o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span lang=EN-US>The reason for this slight delay from now to June is as follows.</span><o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span lang=EN-US>The ISO processes have continued and the 2012 version of OAIS<b> </b>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 (dated Oct 2020) in order to avoid going through the changes resolved previously – details at <a href="http://review.oais.info">http://review.oais.info</a>.<o:p></o:p></span></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span lang=EN-US>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.
