Author and validate Neo4j Ontology Graph Specification (ontology graph spec).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
## When to Use - Authoring an ontology document (Neo4j Ontology Graph Specification) from a domain description - Editing existing ontology YAML/JSON: nodes, relationships, properties, types, constraints, cardinality, extensions - Validating an ontology document against the spec schema ## When NOT to Use - **Cypher queries, or loading/applying an ontology into a database** → `neo4j-cypher-skill` (ontology Cypher procedures do not exist yet — later work there) - **Generic graph modeling advice (node vs property vs label, anti-patterns, supernodes)** → `neo4j-modeling-skill` --- ## Authoring Workflow ### Step 1 — Gather domain intent Identify what is being modeled: entity types (nodes), connections (relationships + direction), properties per element, identifying keys, mandatory fields, cardinality. If the domain or required shape is unclear, ask the user what is being modeled and which questions the ontology must answer. Do NOT guess a domain. ### Step 2 — Draft the document …

How to install
mdr add neo4j-contrib/neo4j-skills/neo4j-ontology-skill@sha256:6ac2caea6a3957a7The line at the top of this page pins the label v1.0.1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
