The digital turn within the realms of both sciences and humanities has facilitated the reclaiming of lost and never-built architectural and urban heritage as digital 3D models. This emergence of source-based hypothetical 3D reconstruction enables the (re)creation of a building's historical narrative in a visually accessible manner. Unfortunetly, the absence of standardized methods for documenting and disseminating 3D data has resulted in a production of tons of outdated, unreadable or unusable datasets within the cultural heritage domain.

This doctoral thesis addresses five key issues related to the lifecycle of digital resources (Fig. 1): the planning phase involving the selection of appropriate digital reconstruction methodologies (Fig. 2), the creation phase focusing on documentation of the process, the publication phase concerning the choice of online repositories (Fig. 3) and rules of Semantic Web, and the subsequent reuse phase necessitating adaptation to conform with the FAIR Principles nad Linked Open Data (Fig. 4) and implementation of exisiting standards for 3D documentation like CitGML or IFC. The study will conclude with the development of a novel CIDOC CRM application ontology, tailored for the documentation of digital 3D recosntructions (Fig. 5). This ontology will subsequently be integrated into a WissKI-based digital 3D repository based aiming at the educational and preservation needs of cultural heritage.
