StratiGraph (Knowledge Graphs for Stratigraphy) aims to transform archaeological and paleontological documentation by developing innovative open collaborative tools that integrate advanced knowledge graphs, artificial intelligence, and 3D field documentation techniques. The project's "Data-Ready" approach enables clean, structured data collection during fieldwork for seamless integration into knowledge graphs without additional curation burden. Key innovations include tools that function effectively in all conditions - a "works-everywhere" solution allowing technology use even where power and connectivity pose challenges. The project will validate these tools through diverse case studies including the Basilica Iulia in Rome, Sarmizegetusa Regia in Romania, St. John Lampadistis Monastery in Cyprus, the Colonia Iulia Ilici Augusta in Spain, the Kraków Spadzista Palaeolithic site, the Santa Olalla site in Spain, and the dataset from Cesarea in Israel. StratiGraph will deliver: -Knowledge graph infrastructure to organize stratigraphic and spatial data -AI-powered tools for creating and enriching annotated bibliographies -Advanced 3D documentation capabilities for recording stratigraphy -Variable connectivity protocols for real-time and seamless offline/online work -Comprehensive training modules and technical support resources The project emphasizes open science principles, with all tools being open-source and data FAIR-compliant. Through integration with the ECCCH, StratiGraph will establish new standards for digital documentation while fostering a skilled, collaborative research community across Europe. This will significantly reduce the time from discovery to publication while improving documentation accuracy and interpretation of our shared cultural heritage. By maintaining exclusive data control and ownership within EU-based institutions, the project supports Europe's strategic autonomy and long-term data governance objectives.
