4.5 Multiple-Classifications
The classifications are not mutually exclusive, and in fact one can think of a simple-
rendered-static-passive object - the image “face.jpg” is an example of this. One can
also have a composite-non-rendered-dynamic-active object such as a database with
built in queries into which new rows are being inserted. The Word.exe executable
file may be thought of as a composite-non-rendered-static-active object.

shows a representation of multiple classifications - although we are
limited to drawing in 3-dimensions!

4.6 Summary
The purpose of this chapter has been to provide a partial view of the variety of
types of digital objects which exist “in the wild” and which one might be required
to preserve. The reason has been to ensure that the reader can at least recognise
the possibilities when confronted with the challenge of preserving a digital object.
Later chapters will discuss preservation techniques for some of this multitude of
possibilities.
