Hi,
The ISO and the CCSDS versions of the OAIS Reference Model are
essentially the same. The ISO version has a couple of pages of
cover sheet attached to the front of the CCSDS version. The cover
sheets are ISO cover, ISO boilerplate of ISO technical authority,
update procedures, etc. replacing the first few pages of CCSDS
boilerplate, and addition/update of ISO numbers for the CCSDS documents
in the reference section.
ISO 14721 available at:
http://www.iso.org/iso/en/CatalogueDetailPage.CatalogueDetail?CSNUMBER=24683&ICS1=49&ICS2=140&ICS3
=
the equivalent CCSDS 650.0-B-1 is available at:
http://public.ccsds.org/publications/archive/650x0b1.pdf
(English)
http://public.ccsds.org/publications/archive/650x0b1(F).pdf
(French)
For those that don't know a French version of the standard was created a
couple of years ago and is now available from both ISO and
CCSDS.
I assume most of you know that both ISO and CCSDS have a 5 year review
cycle. Our working group has recently opened a public comment
period to support our 5 year review of the OAIS Reference Model.
I'll attach the announcement to this message for those who haven't seen
it.
Cheers,
John Garrett
Announcement of a Comment Period for the
Five Year Review of the
Reference Model for an Open Archival Information System (OAIS)
Standard
OAIS Overview
The “Reference Model for an Open Archival Information System (OAIS)” was
developed for use in facilitating a broad, discipline independent,
consensus on the requirements for an archive or repository to provide
permanent, or indefinite long-term, preservation of digital
information. It was also intended to support the development of
additional digital preservation standards and to encourage digital
preservation support by vendors.
An OAIS is an archive consisting of an organization of people and systems
that has accepted the responsibility to preserve information and make it
available to a designated community. The standard defines a set of
responsibilities that an OAIS archive must fulfill and this allows an
OAIS archive to be distinguished from other uses of the term
‘archive’.
Since its adoption as both Consultative Committee for Space Data Systems
(CCSDS) and ISO standards, the OAIS Reference Model has been welcomed and
widely adopted by virtually all types of digital preservation
communities. Most modern digital archiving initiatives reference
the OAIS Reference Model standard. It has also been widely used by
organizations to inform their implementations of new or upgraded
archiving systems.
Five Year Review
In compliance with ISO and CCSDS procedures, a standard must be reviewed
every five years and a determination made to reaffirm, modify, or
withdraw the existing standard. The “Reference Model for an Open Archival
Information System (OAIS)” standard was approved as CCSDS 650.0-B-1 in
January 2002 and was approved as ISO standard 14721 in 2003. While the
standard can be reaffirmed given its wide usage, it may also be
appropriate to begin a revision process. Our view is that any revision
must remain backward compatible with regard to major terminology and
concepts. Further, we do not plan to expand the general level of
detail. A particular interest is to reduce ambiguities and to fill
in any missing or weak concepts. To this end, a comment period has
been established.
Comment Process
We are soliciting recommendations for updates that will reduce
ambiguities or improve missing or weak concepts. We also want to know if
you prefer that no changes be made. Please categorized your comments for
changes under one of the following:
· Updates needed for
clarification
· Updates to add missing
concepts or strengthen weak concepts
· Identification of any
outdated material
Please be as specific as possible with your suggestions. For this
consideration, comments must be received by 30 October, 2006.
Comments may be submitted to: [log in to unmask]
Should the decision be taken to update the OAIS Reference Model, there
should be an opportunity to participate in the process. Please also
express your interest in participating and, if known, an indication of
your expected level of effort.

Hi,
does anyone know more about the contracts of ISO regarding newer
versions or developments of standards? Do followup reports have to
be
published through ISO? And is there a possible Open Access/Postprint
model for such standards?
I don't know which differences occured in the OAIS standard since
the
publication of the Blue Book. Had anyone the possibility to look
into
the ISO-version to compare the two versions?
