Figure 2
Entity–Relationship (ER) diagram of the 1808 Sommarioni dataset. The diagram illustrates the three main components: Standardized People, which contains uniquely identified individuals after the disambiguation process; Textual Entries, which describe parcels and ownership information transcribed from the registers; and Geometries, which store the vectorized cadastral parcels. The Merge Log records the criteria applied to link multiple mentions of the same individual across parcels.
