Information Technology Reference
In-Depth Information
Emulation has its place in preservation but as we point out in
Sect. 7.9
,this
is limiting not least because in essence one is limited to what has been possible
with the digital object in the past. Moreover especially because the semantics of the
digital object are not made explicit in the TDO, even if one could link the emulation
to modern applications, one would be limited with what new things could be done.
The XFDU is not tied in any way to emulation, although an emulator can be one
part of the Representation Information in the package. Therefore it is fair to say that
the XFDU is a superset of the TDO technical concept.
11.4 Summary
Packaging is an important requirement with many possible solutions. This chapter
has tried to elucidate the key considerations and describe in some detail one possible
packaging mechanism.
