Expand description
Standalone OxGraph-native database engine.
oxgraph-db is a product layer above the topology substrate. It owns
durable database identity, cataloged physical projections, properties,
indexes, native OxQL execution, the pinned Cypher profile, and embedded
transaction semantics. Foundation crates remain storage- and
meaning-neutral.
