Massimiliano Geraci – Beyond RDF vs LPG: Operational Ontologies, Hybrid Semantics, and Why We Still Chose a Property Graph:
„This is the story of how we ended up with a hybrid system — Weaviate + Neo4j + Postgres + JSON Schema — while still respecting the very real arguments from the RDF world.“
„Two things are different from classic RAG: 1. The context is alignment‑checked against a graph of truth. 2. We have a hard threshold: if retrieval + alignment are too weak, we return ‚Unknown’ or ‚we don’t have enough verified information.’”
