As explained here, in Geovistory, information is stored in two types of entities; persistent items and temporal entities.
This means that in your project, all persistent items are linked with one another via temporal entities. For example, two married people are linked to each other via the temporal entity 'union'. The same temporal entity also connects parents to their children.
This information structure allows you to jump in your project from entity profile to entity profile and to inspect and complement the information as you wish, as demonstrated in the clip below.
