Neo4j open-sources an ontology spec: versioned YAML schemas with JSON Schema validation for GraphRAG
JeremyCMorgan · x · 2026-11-10
Jeremy Morgan highlights Neo4j's open ontology-graph-spec: while most GraphRAG schemas live inside prompts or Python dicts, this spec moves them into versioned YAML/JSON with JSON Schema validation, plus libraries for JVM, Kotlin, TypeScript/JavaScript and Go (Apache-2.0 on GitHub). Early-stage, but a useful step toward making extraction schemas reviewable.
