Prototypes Synthesis:

While the individual case study systems have distinct
limitations, they all represent some degree of viability as data
retrieval (HSPD) or information management (CRISTAL,
PC-Hypertext) solutions for the preservation community.  In
addition, opportunities exist for the enhancement of each of
these systems through software and hardware modifications.  These
modifications would redress at least some of the limitations
associated with each system, and could make the systems more
suitable for the preservation applications considered in this
research effort.

However, rather than discuss particular system modifications that
might quickly be invalidated in the context of the ever changing
performance parameters of computer hardware components and
software packages, it is more appropriate to simply propose a
litany of performance specifications that would effectively
characterize a contemporary preservation information management
system.
