Advantages<br />
• as an <strong>in</strong>terim measure, it could provide repositories<br />
with an option of retriev<strong>in</strong>g obsolete document for some<br />
years <strong>in</strong>to the future<br />
Migration Strategy<br />
7. Save the software needed for access and retrieval:<br />
[This strategy is closely related to 3].<br />
8. Develop software emulators:<br />
An alternative to preserv<strong>in</strong>g software is the development of<br />
new programmes that can 'emulate’ (i.e. replicate) the<br />
functionality of obsolete software. If this strategy is used, it is<br />
critical to have access to documentation of the orig<strong>in</strong>al<br />
software system that expla<strong>in</strong>s the precise software<br />
requirements needed to open and retrieve a document and<br />
these must be written <strong>in</strong> a software-<strong>in</strong>dependent form.<br />
• does not require access to the same hardware and/or<br />
software used orig<strong>in</strong>ally for the <strong>in</strong>itial application<br />
Disadvantages<br />
• the technical complexity of preserv<strong>in</strong>g<br />
software; most software is written to work only<br />
with specific hardware. As a result, sav<strong>in</strong>g<br />
software also implies sav<strong>in</strong>g the hardware<br />
needed to run it.<br />
• special programs have to be written to emulate<br />
the obsolete software<br />
• can be an expensive and complicated undertak<strong>in</strong>g;<br />
<strong>bodies</strong> consider<strong>in</strong>g this approach will<br />
need access to highly competent software<br />
designers and programmers<br />
• not fully tested<br />
• copyright issues have not been resolved<br />
