In ELAN it is possible to associate an individual annotation with a data category of the ISO Data Category Repository (DCR). To do so first select an annotation. Then click in the main menu of ELAN and select (alternatively press ALT+SHIFT+M). In the next window (Figure 5.87), select a data category from the list and click on to associate the selected data category to the annotation.
More information about the ISO DCR and how to use it can be found in Section 5.2.
