Abstract
Semantic technologies are rapidly changing the historical research. This paper focuses on the knowledge representation and data modelling initiative that has characterised the first year of the EPNet project in the context of the historical research. The so-called EPNet CRM and Ontology are introduced here, and put in connection with existing modelling standards. The formal specification of the domain expert knowledge is the preliminary step toward the design of an innovative ‘Virtual Research Environment’ for scholars of the Roman Empire. Potential and actual benefits coming from the knowledge representation initiative are also discussed, with the main aim of encouraging experts in the humanities in embracing an innovative paradigm whose proved efficacy can positively affect their current research practices.
