StratiGraph (Knowledge Graphs for Stratigraphy) aims to innovate archaeological and paleontological documentation through the development of open and innovative collaborative tools that integrate advanced knowledge graphs, artificial intelligence, and on-site 3D documentation techniques.

Funded by the European Union under the Horizon Europe programme, within the ECHOES (European Cloud for Heritage OpEn Science) project, StratiGraph’s mission is to modernize archaeological and paleontological workflows by bridging the gap between field excavation and scientific publication. To achieve this, the project is developing a suite of “data-ready” tools designed to collect clean, structured data directly in the field, enabling seamless integration into knowledge graphs without the need for time-consuming curation phases.

Within StratiGraph, 3D Research plays a key role in developing modules for 3D acquisition, modeling, and analysis. It also designs interoperable pipelines that integrate complex spatial data into the project’s AI platform.

Main objectives include:

• Developing a Stratigraphic Knowledge Graph (SKG) aligned with the ECCCH (European Collaborative Cloud for Cultural Heritage) standards, capable of dynamically representing stratigraphic relationships, temporal sequences, spatial data, and interpretative layers.
• Integrating traditional 2D documentation with advanced 3D methodologies to enable real-time semantic annotation and volumetric analysis of archaeological contexts.
• Deploying an AI-powered infrastructure optimized for field use, automating document analysis, metadata extraction, and semantic linking, while ensuring scientific rigor and full traceability.
• Introducing a “ready-to-publish” workflow that transforms field documentation into publishable content through automatic validation and standardized templates.
• Creating a comprehensive training ecosystem through the StratiGraph Academy, combining hands-on workshops, e-learning, and micro-grant programs.
• Ensuring full interoperability with ECCCH for smooth data exchange and integration with European research infrastructures.
• Implementing an offline-first architecture with VCP support to guarantee documentation and collaboration even in variable connectivity conditions.

Bringing together 16 international partners, StratiGraph aims to deliver a fully interoperable Stratigraphic Knowledge Graph integrated with the ECCCH, capable of linking archaeological and paleontological datasets. The project will develop AI tools for speech recognition, document and shape analysis (also functioning offline), a hybrid 2D–3D system with semantic annotation, a “ready-to-publish” framework, cascade-funded training programs, FAIR integration with ECCCH, and sustainable open-source software.
