Towards EUROGLOSS: an Interoperable Knowledge Infrastructure for Built Heritage

This paper presents the methodological and technical requirements of EUROGLOSS, a digital platform designed to host a multi-layered repository of construction documents related to Modern Age European Royal Residences. By aligning with the FAIR principles, EUROGLOSS aims to establish an interoperable framework where standardized construction terminology is transformed from heterogeneous archival sources into ontological entities, serving as a functional tool for real-time intelligent services. Given that Modern Intelligent Reality (IR) applications require high-fidelity data to bridge the gap between physical architectural assets and their historical evolution, the EUROGLOSS repository can act as a semantic backbone for Knowledge Digital Twins, able to provide practitioners and conservation authorities with actionable historical evidence. To ensure a robust framework, a comparative analysis of representative global digital platforms was conducted, evaluating metadata schemas and system architectures.
