Announcement of a Comment Period for the Five Year Review of the Reference Model for an Open Archival Information System (OAIS) and ISO 16363.

09 Aug 2016

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 long-term, preservation
of digital information. It was also intended to support the development of
additional digital preservation standards.
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 fulfil and this allows an OAIS
archive to be distinguished from other uses of the term archive.
Since its adoption as both a Consultative Committee for Space Data Systems
(CCSDS) and an ISO standard, the OAIS Reference Model has been welcomed and
widely adopted by virtually all types of digital preservation communities.
Most modern digital preservation initiatives reference the OAIS Reference
Model standard. It has also been widely used by organizations to inform
their implementations of new or upgraded preservation 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. A comment period for that first
issue of the OAIS standard was held at the end of 2006. Based on the
comments received, CCSDS began work on a new issue of OAIS. Issue 2 of
OAIS, CCSDS 650.0-M-2, was published in June 2012 and was approved as an
update to ISO 14721 in August 2012.
The Issue 2 updates include clarifications to many concepts, in particular
Authenticity with the concept of Transformational Information Property
introduced; corrections and improvements in diagrams; addition of Access
Rights Information to Preservation Description Information. With those
updates the OAIS standard continues to garner widespread and growing
recognition and acceptance in the digital preservation communities.
While the current issue of the standard can be reaffirmed given its wide
usage, it may also be appropriate to begin another revision process. As with
the previous update, 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 nor will the standard be changed
from a reference model to an implementation design. Archive implementation
standards or implementation profiles or detailed archival process standards
or protocols should be addressed but they would become separate standards
and would be developed through separate CCSDS projects. A particular
interest for the current OAIS update is to reduce ambiguities and to fill in
any missing or weak concepts and to add useful terminology. 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 categorize your comments for changes under one of
the following:
* Editorial
* Corrections to matters of fact
* Updates to add useful terminology
* Updates needed for clarification
* Updates to add missing concepts or strengthen weak concepts
* Identification of any outdated material
* Recommended change for other considerations
In addition, any backward compatibility issues should be indicated.
Please be as specific as possible with your suggestions. If possible,
comments should be received by 7 October, 2016, but additional comments will
be accepted up to 31st December 2016.
