The preservation of cultural heritage faces increasing challenges from environmental, climatic, and anthropogenic pressures. The ARGUS Horizon Europe project addresses these challenges by proposing an innovative predictive preservation approach that leverages AI-driven digital twins and multimodal data fusion to assess and mitigate risks to heritage sites. Our research focuses on developing a sustainable, dynamic decision support system (DSS) that integrates multi-scale on-site and remote sensing data, enabling holistic heritage management, while focusing on the preventive rather than the reactive aspects. The primary research question treated in this paper relates to how digital twins incorporating multi-dimensional data and an ontology background enhance the preservation and adaptive management of cultural heritage in a changing environment.

This article provides an overview of the current situation in Greece regarding digital archaeological data stewardship. A brief chronicle of Greek archaeology sets the scene for a better understanding of the present situation. Greek archaeology is supervised by the Ministry of Culture and Sports, with the Archaeological Service as the central organisation in charge of antiquities. However, archaeological data resulting from archaeological fieldwork are produced by several other entities. This article presents the policies governing both physical and digital documentation archives. It introduces the current practices for archaeological data preservation and the relevant digital infrastructures, attempting to showcase the existing environment. We categorise prevailing problems on three levels, all based on the fact that digital and open access arrived recently in a well-established environment formed gradually over almost two centuries. Even so, fragmentation and variation would be the proper terms to describe the status of the stewardship of digital archaeological data in Greece. Our review shows that there is substantial effort directed towards digital archaeological data stewardship and accessibility by all stakeholders within the archaeological sector. Finally, we add a few thoughts and suggestions, and indicate the need to generate a network that could take steps towards more inclusive strategies within digital data stewardship. The key to leveraging change is raising awareness about data sustainability and reuse, and the COVID-19 outbreak indicates a clear change in mentality in this direction, since open access resources have begun to be key to education and research conducted in Greece.

Отделът за култура и творчески индустрии на Изследователски център Athena Ксанти (Гърция) се фокусира върху използването на различни дигитални инструменти за археологически изследвания. Чрез различни проекти се използва широк набор от дигитални инструменти за изучаване на историята и археологията на древна Тракия. Въз основа изследването на различни критерии са анализирани разпространението, употребата и културното значение на атическите вази в древна Тракия. Изследването на древните митове и връзката им тракийския ландшафт показа културния туристически потенциал на Източна Македония и Тракия. Освен това, използвайки ГИС софтуер, лабораторията AeGIS проучи различни археологически теми чрез използване на символи и инструменти за количествен анализ, както и топлинни карти и инструменти за реконструкция на мрежа.
