Extended Matrix

Extended Matrix is a formal framework designed to document, structure, and interpret the full lifecycle of archaeological and architectural knowledge production. It integrates stratigraphic analysis, virtual reconstruction workflows, and multi-layered data interpretation into a unified, graph-based representation that ensures scientific transparency and methodological traceability. By distinguishing raw evidence, interpretative hypotheses, and procedural steps, the system supports reproducible research and enables the creation of FAIR-oriented datasets. Extended Matrix allows users to link heterogeneous information—from excavation records and building archaeology to 3D surveys, diagnostic analyses, and simulation outputs—into coherent, navigable knowledge structures. Its main objectives include formalizing and visualizing interpretative reasoning, ensuring provenance and versioning of data and hypotheses, supporting diachronic and multi-scalar documentation, and fostering collaborative research environments through interoperable tools that connect physical evidence with digital workflows.
