The extracted Turtle (TTL) file is an RDF export of the knowledge graph created in the HybridDigital project. It contains the project’s graph content in the form of subject–predicate–object triples, i.e., explicit semantic statements rather than tabular records. The graph represents knowledge about hybrid material specimens and related research outputs, covering both experimental and simulated data. It captures the involved physical entities (e.g., specimens and their constituents), the relevant processes (e.g., manufacturing and testing activities), and the resulting information artifacts (e.g., measurements, computed results, and derived assessments). For semantic alignment, the graph follows a layered ontology approach: BFO (Basic Formal Ontology) is used as the Top-Level Ontology (TLO) to provide the foundational categories for entities and processes. CCO (Common Core Ontologies) is used as the Middle-Level Ontology (MLO) to supply reusable mid-level concepts and relations that structure scientific/engineering information, measurement representations, and artifact-related modeling. Domain-specific terms (project/manufacturing/materials concepts) extend this foundation where needed.
