Perhaps the best strategy depends on purpose and time scale.
For active research in rapidly changing fields and over 0-2 years it
seems like portable representation of the original data is best, as
For reproducibility of research in the 1-5 year time span, it seems like
one would like to archive or retain access to the original software and
processing scripts, in addition to the data.
Over longer periods it's difficult to find hardware, compilers, etc to
make use of old software, and perhaps the best bet is archived, updated
objects like the ALL data set that represent a snapshot of partially
processed data. This implies that someone with sufficient familiarity
with the software has been conscientious enough to provide facilities
for updating objects to work with current implementations, or
alternatively conservative enough (perhaps because something close
enough to the 'right' representation has been identified) not to modify
the underlying data representation.
