Hi John
One immediate, absolutely fundamental, question arises from your comments,
for example your first comment:
Although information exchange rather than data exchange is an admirable
goal, I thought main purpose of OAIS-IF was interoperability. I think we
should be aiming for interoperability whether information or data is
exchanged.
The question is "What is interoperability?". We need to agree on that
otherwise we are talking at cross-purposes.
http://interoperability-definition.info/en/ has a definition:
Interoperability is a characteristic of a product or system, whose
interfaces are completely understood, to work with other products or
systems, present or future, in either implementation or access, without any
restrictions.
My understanding was that to have interoperability of information from
different domains, say Solar studies and Meteorology, one needed to be able
to "combine" ("work with") the information from those domains e.g. plot the
heat output from the Sun against weather patterns to see if Global Warming
is caused by the Sun rather than Man. This requires more than just getting
the data - which one can probably do already pretty easily. My belief was
that this is why we are talking about an OAIS-IF - because one of the OAIS
fundamental drivers is about understandability and usability.
Maybe some would think that interoperability is just finding relevant
information e.g. where are is Solar energy output data? Well there are lots
of things that exist already e.g. Google.
Maybe some would think that interoperability is just getting the data from
multiple domains together. Well again that is pretty easy right now. Besides
which isn't the fundamental point in OAIS that we need more than the Data
Object?
My question is "What does an OAIS-IF need to do?" in other words , what is
the link to OAIS? Since we said this was not about the internals of the
archives, OAIS-IF is not about the details of preservation, except when one
os transferring (copies of) AIPs to another archive as part of the
preservation strategy.
To my mind the answer is that it has to deal with
understandability/usability of the information which is encoded in data,
together with evidence about Authenticity.
Perhaps we can discuss this today.
Regards
..David
