From the Domus of the Scipios to the Basilica Sempronia: Semantic Annotation in Virtual Reconstruction Using the Extended Matrix

This thesis presents the digital reconstruction of two superimposed Republican phases in the Forum Romanum, the Domus of the Scipiones and the Basilica Sempronia, as a contribution to the Basilica Iulia Project. The two buildings are known from the Carettoni and Fabbrini campaigns of 1960 to 1964, published by Galli and Ismaelli in 2022, and from a photogrammetric survey of the site. The reconstruction follows the Extended Matrix. Both phases were modelled as proxy geometry graded by certainty, with every element linked to its sources through a knowledge graph and listed in the catalogues. The method was checked against the London Charter and the Seville Principles for transparency, traceability and verifiability. The relation between the two phases is superimposed, and in the sector studied here it is also intrusive: the Basilica Sempronia was cut into the Domus. Recording this required a notation for removal, not only for succession. The work takes a single cut as a case. The notation absorbs it without modification: a negative unit carries the same paradata chain as any other. The proxy model holds the two states, before and after, and the cut was given no geometry, so the transformation is documented rather than modelled.
