Common data environment for knowledge management of historic built heritage. The study case of the Pieve di Santa Maria in Arezzo

Building Information Modeling and Management methodologies has been emerging also in the field of cultural heritage, bringing out the need to define a specific approach to the processes of information production, which characterize the activities of protection, conservation and maintenance of built heritage. In this case the process of digital models authoring have to deal with both the particular methods of acquiring the geometric data in the different digital survey techniques, and implementation of information content not only related to technical parameters, but also to the historical and cultural values through semantic connections referable to proper ontologies of historical analysis and architectural codes of the past. The proposed work shows some results of the experimentation of a common data environment aimed at the knowledge management of the ancient parish church of Santa Maria in Arezzo, developed through the design of a relational database capable of exchanging data and information with the H-BIM model, creating a Relational Database Management System (RDBMS).
