Ontological Issues in Architectural Digital Heritage Interdisciplinary World

The growing of digital tools – often of ease and affordable use –, the rise of ICT, the diffusion of digital devices, have brought to the spread of 3-D models, computer-based visualization, and the rise of advanced applications and of new scientific methodologies. The common practice with digital heritage, its affordances, and the interoperable use of digital instruments favour interdisciplinary works and collaborations between scholars and professionals. According to this context, aim of the paper is to offer a critical reflection on characteristics of architectural heritage and how digital heritage has influenced the discipline, to define references on which root interdisciplinary collaboration, underline peculiar aspects and suggest critical approaches for a wise use of digital tools, foster the study of experiences made in different fields, and support a useful collaboration between researchers of different fields.
