Ontology Schema v0 — Digital Twin Property Graph

v0 Prototype — Semiconductor Supply Chain Ontology Schema

Defines the complete ontology schema for the Project TBD digital twin: every entity type, field, relationship type, and property that the v0 property graph will model. Authoritative reference for graph database implementation, LLM query layer construction, and data ingestion pipelines.

Implementation: Neo4j (Community Edition for v0), queried via Cypher. LLM query layer: LangChain GraphCypherQAChain.
