CENSUS OF ABANDONED BUILT HERITAGE ASSETS: THE IMPORTANCE OF DEFINING SHARED METHODOLOGIES AND ONTOLOGIES

Abstract. The paper shows the studies carried out within the framework of two research agreements for the census of abandoned enlisted assets owned by public bodies in the Provinces of Piacenza, Parma and Reggio Emilia, stipulated with the respective Heritage Departments. The purpose of this research is to increase the cognitive framework of cultural assets in a state of abandonment, and then to transfer the results to the dedicated WebGIS platform, with the aim of identifying the ones which are most in need of a conservation and reuse intervention, in order to return them back to their community. Afterwards, as a result of the cataloguing carried out, it was possible to make some critical considerations and statistical reworkings of the collected data. The data analysis, performed through the design of a GIS database, finds out a higher frequency of abandonment for some specific building types and with recurring locations. The research also highlights, once again, the importance of defining common ontologies, which are essential for statistical data processing and interoperability between different existing databases.
