All-in-one approach:
shown in Fig.
14.19
, is to archive a more standalone AIP,
containing a digital asset together with all of the RepInfo deemed necessary
by the designated community at the time embedded within the same container
(e.g., a ZIP or TAR file). The advantage of this solution is that all the informa-
tion objects are kept together and hence immediately available, this approach
removes reliance on a remote registry which may or may not be accessible long
term. The producer would need to make a decision as to what level the embed-
ded RepInfo dependencies should terminate at, in order to satisfy the community
needs. This scenario presents the lowest preservation risk however could prove
to be a cumbersome and impractical solution in situations which involve large
data holdings or extensive RINs.

Representation Information Network (RIN):
The RIN solution is to archive
the digital asset with the XFDU manifest referencing an external RIN held within
a registry like RORRI via CPIDs. This scenario is illustrated in Fig.
14.20
.The
main advantage is to store the asset independently of its community built RIN,
which is itself separately and securely managed and maintained remotely from
the digital data itself. Giving the advantage of RepInfo reuse, the network may be
applied to multiple data sets within the holdings of many archives. This solution
