Draft text for Introduction to review.oais.info


The open process used since 1995 to create and revise OAIS has contributed
to its success. 

The CCSDS and ISO process is rather formal and is documented in
https://public.ccsds.org/Pubs/A02x1y4c2.pdf. CCSDS follows the ISO code of
conduct to ensure it addresses consensus, transparency, openness,

Although CCSDS is an organisation created and managed by the space agencies
it welcomes participation from industry, academia and outside organizations.

The CCSDS-DAI working group is, among other things, in charge of
coordinating the Five Year Review of OAIS that includes gathering and
adjudicating all comments, creating the consensus revision, and coordinating
the review and approval of the revised OAIS standard. The working group is
open to all; to participate, one should join the MOIMS_DAI mailing list at
https://mailman.ccsds.org/cgi-bin/mailman/listinfo/moims-dai. This mailing
list is used to co-ordinate discussions and meetings. The website
http://review.oais.info is being used to record, discuss and reach consensus
on the suggested revisions; to contribute to the site one can create an
account at http://review.oais.info/createaccount.cgi. Most work is carried
out by email and this is also used to send out agenda and details for the
weekly virtual meetings. 

CCSDS management has approved a schedule
<http://cwe.ccsds.org/fm/Lists/Projects/DispFormDraft.aspx?ID=581>  to
produce a revised draft of OAIS by the end of 2017. Of course this could be
completed earlier but past experience suggests that to reach consensus takes
time. The draft is then submitted for review by the management of CCSDS and
TC20/SC13 of ISO who will circulate the draft to their wide set of contacts
around the world and coordinate the responses and return them to CCSDS-DAI.
The draft will also be circulated widely by CCSDS-DAI itself. Ideally all
the issues will have been addressed during the development of the draft.
However further issues may be pointed out and these must be discussed and
the issues resolved by reaching consensus. A second round of reviews may
then be necessary. The schedule is to publish the new issue of OAIS by CCSDS
and ISO by mid-2019. 

This is a long and involved process but is the one which has been well
proven by CCSDS and ISO and has contributed to the success of OAIS. 

In order to ensure the continued usefulness of OAIS any revision must remain
backward compatible with regard to major terminology and concepts. Further,
for consistency the general level of detail should not be changed nor should
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
