<br/><br/> ‪This paper points up the need to distinguish various levels when creating a historical database, starting with a first layer, at the time of data input, in which the information is segmented into independent “actions”, each one characterized by a minimal ontology comprising the following dimensions: Who, What, Where, When, With whom. One or more layers can then be added at a later stage, describing and developing, if the current research so requires, each of those actions into more complex ontologies. This progressive approach resolves a problem encountered with most databases, stemming from the need to define and manage huge ontologies whose volume and complexity extend far beyond the cognitive capacity of the operators in charge.‪
