7.7.5 Static
Static Digital Objects are those which should not change and so all the above
examples, the JPEG file, the NetCDF file etc fall into this category.
7.7.6 Non-static
Many, some would say most, datasets change over time and the state at each par-
ticular moment in any time may be important. This is an important area requiring
further research, however from the point of view of this document it may be useful
to break the issue into separate parts:
at each moment in time we could, in principle, take a snapshot and store it. That
snapshot would have its associated Representation Network.
efficient storage of a series of snapshots may lead one to store differences or
include time tags in the data (see for example [ 67 ]). Additional Representation
Information would be needed which describes how to get to a particular time's
snapshot from the efficiently encoded version.
