AbstractOver the last decades, archaeology has experienced a transformative revolution in the wake of the digital that has shaped the ways in which it is researched and published. A key concept, openness, has emerged from this shift. This article explores digital approaches to data management conducted within the framework of the PERAIA project, which provides a comprehensive open database and a web application that integrate data on archaeological heritage spanning from late prehistory to antiquity, covering the Aegean area (Crete) and northeastern Libya / northwestern Egypt (Marmarica). We used a methodology that integrates legacy data with historical aerial and satellite imagery to identify archaeological features in the landscape, thereby enriching them with associated environmental and historical (meta)data. Our open data practices reflect a commitment to open science, in which digital technology and the LOUD+FAIR principles have been at the core of the project to achieve data openness, fair access to information, and enhanced data reusability potential.
