HBIM Feeding Open Access Vault Inventory Through GeoDB HUB

This paper describes a methodological workflow starting from a punctual informative Historical Building Information Models (HBIM) - derived from the geometric analysis of the construction technology of vaulted systems - used to feed an open access Geospatial Data Base based on a Virtual Hub technology. Vaulted systems, which are characterized by a variety of solutions developed across time and space, and whose knowledge is obtained during the analysis and diagnostic phases planned for preservation purposes, are mostly unknown to the public and collected information risks to be missed. This way, the chain of knowledge transfer is interrupted both for more informed future sustainable interventions and touristic purposes. The potentials offered by the adoption of a Pan European Virtual Hub to manage open data with semantic, spatial and temporal sub-setting allows to reconstruct a new framework of the construction techniques widespread across the world, permanencies and mutations to the common typologies with the contribution of skilled workers moving during the centuries across Europe. The case study of Palazzo Magio in Cremona with a rich abacus of vaults apparently belonging to a simple ‘cloister’ typology is described from the HBIM generation to data publication in the GeoDB HUB. Different Level of Detail, Geometry and Information, acquired in other Cremona Palaces, are feeding the DB and its vocabulary in a bottom-up process. The result is a contribution to the construction of an open access updatable inventory model inheriting the tradition of historical repertoires.
