Knowledge Graph Schemas
Formal schema for registering, querying, and deleting triples with provenance and governance metadata.
Triple model
`GraphTriple` includes subject, predicate, object, confidence score, and provenance references to maintain trust chains.
- `confidence` ranges from 0-1 to indicate reliability.
- `source_reference` links back to episodic or document stores.
- `ttl` optional field controls expiration.
Query payload
`GraphQueryRequest` defines match patterns, traversal depth, filters, and aggregation instructions.
- Supports sorting by freshness, confidence, or relationship weight.
- `include_evidence` bundles source excerpts automatically.
- `policy_context` enforces namespace-level permissions.
