description: Historic urban environments are not given static formations disconnected from the contemporary fabric of a city, but rather a set of tangible and intangible assets subjected to dynamic pressures of economic, environmental, and social activities. The sustainable development of these environments is often threatened by urbanization, neglect and climate. The cross-disciplinary nature of the pressing challenges posed by these phenomena (Historic England 2020) requires the development of novel data-driven tools for agile safeguarding of our historic building stock. In an era of rapid technological developments due to digitization initiatives, state-of-the-art methods and data-driven tools dedicated to the protection and promotion of architectural heritage should be exploited and extensively employed in the sustainable management of built environment. The adoption of holistic, integrated, multi-disciplinary methods can bridge technological innovation with the conservation and restoration of heritage buildings. The next step in the development of built heritage digitisation methods should focus in expanding the scope of study beyond the single built heritage structure and allowing deeper understanding and interdisciplinary interpretation of its condition and performance within its topographical context and the surrounding built environment. This could become a reality today by means of the advancements in digital tools, remote sensing, algorithms and computation prowess of hardware available to researchers (Mohamed et al. 2020). Data interoperability and re-use, in the context of the FAIR principles, can only be achieved through the semantic description, using metadata and ontologies (Messaoudi et al. 2018). Arguably, the penetration of Building Information Modelling software in the building industry is enabled by semantic tools, such as the Industry Foundation Classes (IFC) data model (2022) or the Green Building XML schema (gbXML, 2023). Acknowledging this, the research presented here explores possible specifications and metadata schemas which facilitate interdisciplinary research for the study and reuse of built heritage in our cities, analysing and representing scales larger than the one of the building itself, including building blocks, streets, or even neighbourhoods. The authors will present: Challenges and practical aspects of the creation of a new metadata schema that would enable linking the relevant to cultural heritage of our historic cities’ multi-modal and multi-discipline datasets, e.g., 3D models, IFC classes, historical descriptions, and environmental data. How this multiscale data-driven study can facilitate a more holistic, integrated application of digital methods, such as BIM, modelling &amp; simulation to cities, and better contextualise cross-disciplinary enquiries (Cursi et al. 2022[GA1] ). . The paper will assess a series of existing metadata schemas such as bibliographic documentation or geoinformatics, that are required to be added to the BIM model in order to meet the specifications of a CIDOC-CRM based on ISO standards ISO 21127:2014 (Acierno et al. 2017). The result of this action is the description of a new metadata schema, CIDOC-CRM compatible, as an extension of the CARARE 2.0 metadata schema (Fernie et al. 2013) for built heritage and monuments (English Heritage 2012). The authors expect that the results of this activity will contribute to the long-standing discourse in the field (Ronzino et al. 2013; Ronzino, Niccolucci and D’Andrea 2013), to support in the future the big data management of historic cities. In this effort, a further step, currently under completion, is the alignment of the proposed metadata schema to the CIDOC CRM ontology and its extensions (Fig. 2). The semantic integration will allow the holistic description of the different aspects of the Architectural Heritage and provide a multidisciplinary perspective to its study, including historical and landscape analysis, environmental investigations and climate change impact on its conservation and preservation. The final results of this activity will be published on Zenodo and also disseminated to the relevant digital humanities communities through the DARIAH ERIC WG on Digital Practices for the Study of Urban Heritage.
