I suggest the attached technology neutral ISO "Life expectancy" standard
be considered in the ongoing Digital AV Archive debate.
Russ Burkel

These ANSI standards are in reality ISO standards.  ANSI IT 9.13 has
been
given a designation of ISO 18913 but is not yet published as best I can
tell.  However, ISO 18901-2000 has been published and states the
definitions the same way as below.   

You can find these at:

Clearly, the intention of the term Life Expectancy is to define the
length
of time that a system can provide access to the information.  I would
take
that to mean it includes media, software, hardware or whatever else is
required to be able to "access" the information.   By the way, it also
takes
into account environmental and enclosure characteristics as well.  For
instance, storing film in a moist warm bacteria ridden room is
tantamount
to storing magnetic tapes or diskettes next to a magnet or CDs in an
environment that breaks down the chemical structure.  The significant
point
of the attached was that paper and film by being human decipherable
analog form
do not have as many systems issues for determining retrievability.
