Last week ISO published the new version of the basic standard in digital preservation, the OAIS reference model ISO
14721:2012. After consulting the community a few years ago, we can now see what has changed and added to the OAIS standard. A change bar in the margin indicates the places where text is changed or inserted. But I found it more convenient to
have an overview of the changes. So I compared the 2002 version with the 2012 version and you can read the result on my personal blog http://digitalpreservation.nl/seeds/standards/oais-2012-update/

As usual you can download the text of the OAIS standard from the CCSDS website http://public.ccsds.org/publications/archive/650x0m2.pdf or buy it at ISO www.iso.org .
