The LD4HE data model is based on a subset of the CIDOC Conceptual Reference Model (CRM). The following pages give further details of distinct aspects of the LD4HE data model:

Figure 1 below gives an indication of how each of these aspects are interlinked in the overall model. The dataset is composed of records referring to investigations. Investigations are carried out by organizations at sites during time-spans. Report production produces reports that document the investigations.
