# Overview

The knowledge graph has two distributions. `./ai graph --export --byod` writes the merged graph as `graph/ai-risk-ontology.yaml`: the packaged ai-atlas-nexus data plus the files under `byo/data/`. `just fetch-cypher`, or `./ai graph cypher --export`, downloads `graph/cypher/ai-risk-ontology.cypher`, the Cypher export ai-atlas-nexus publishes at the tag of the installed version. The saved file starts with three comment lines naming its source URL, its ai-atlas-nexus version and the fetch date, and it is not committed.

The two differ in scope. The YAML export honours `--byod`. The Cypher export is built upstream from the packaged data only, so `--byod` on it is refused with a 400. The Cypher distribution is what the [Neo4j graph database service](../services/graph-db.md) imports.

Both distributions can be rebuilt: the YAML from the packaged data and `byo/data/`, the Cypher from upstream's tagged release.
