# Bring Your Own Data (BYOD)

**BYOD** means your internal policies, encoded in the same schema as the public frameworks so that they are queryable alongside them.

In practice it is a schema-compliant YAML file in `byo/data/`. The CLI, the API and the web UI pick it up through the `--byod` flag or curate mode, and the exposure file, `ai-risk-ontology-linkmo/exposure.yaml`, declares the flag as the `byod` query parameter of every class. The Cypher export for the graph database refuses `--byod`, because ai-atlas-nexus builds that export from the packaged data alone. The nine framework encodings included in the repository are themselves worked BYOD examples. The [BYOD playbook](../playbooks/bring-your-own-data.md) gives the procedure.
