In the first sub-sequence (Figures 6.7 and 6.8), the analyst is invited to denote the
historical era in which the knowledge object thematized in the audiovisual text being
analyzed is located. In other words, the analyst himself decides what to call that
historical period. Thus, it is a procedure of so-called
free description*
(see Chapter 9) of the relevant historical context.
Figure 6.9, on the other hand, shows an example of controlled description of the
relevant historical context. In this concrete example, it is a question of historically
locating a French archaeological site in the era <France in Celtic times> (this era
forms part of the ASW micro-thesaurus devoted to named eras in the history of
France).
