6. Representational relations

The same information can be represented in different formats. In the module Treated results, for instance, results can be represented in a tabular as well as a graphical format. This holds in particular for a presentation of information in a hypermedia environment. The relations between different representations of the same information are asymmetric `representational relations':

A representational relation is an organisational type of relation, as it deals with the symbolic representation of the information rather than the scientific content itself. Contrary to the other organisational relation types, the relata are not necessarily modules as a whole, but they can also be segments of modules. For example, the relata of a particular representational relation can be a pictorial representation and a textual representation of the same information. A link expressing that relation then carries labels indicating, in one direction, that a pictorial version of the text is given, and, in the other direction, that a textual version of the picture is given.

In our analysis, we focus on the organisation of scientific information, and not on its particular representation. Therefore, we shall not take representational relations into account. Still, the model explicitly allows for them, because the availability of different (audio-visual) means to express information is an important feature of the electronic, multimedia publishing environment.
