Deduction at the core.

RDFS+, OWL-RL, and Datalog reasoning plus SHACL validation run where the graph lives. Every query language reads the results.

Standards-based deduction

RDFS+ and OWL-RL entailment: deductive AI grounded in W3C standards.

Recursive rule programs over the same graph, beyond the standards.

Validation and pre-commit rules enforce the model before knowledge lands.

Entailed facts are first-class graph state. No sidecar service, no export step.

SPARQL

Native RDF entailment, straight from the standards.

Cypher

Property-graph queries read the same entailed facts.

GQL

ISO graph language clients query deductions too.

Inference, validation, and rules are substrate. They make the graph a trustworthy corpus for people and agents.
