OntoBroker 7

Enterprise reasoning for decisions you can explain

Meet OntoBroker

OntoBroker 7 is semafora’s enterprise ObjectLogic reasoner for active ontologies. It turns governed facts and higher-order rules into repeatable conclusions, actions and explanations. Built on decades of enterprise use, version 7 brings this reasoning foundation to Java 21 with secure remote integration, modern persistence and production-oriented operations. OntoBroker 7 is commercially available; contact semafora for licensing, deployment and migration.

Turn Knowledge Into…

Explainable Apps

Build explainable enterprise applications that evaluate governed facts, rules and policies through OntoBroker reasoning.

Core Capabilities of OntoBroker

Represent facts, relationships, constraints and higher-order rules in ObjectLogic, the foundation of OntoBroker 7. Model complex enterprise domains as active ontologies and keep business knowledge explicit, inspectable and reusable.

Integrate applications through the Java 21 client with mutual TLS and certificate-governed authorization. Use supported relational access and bounded REST/JSON and SOAP/WSDL connectors. Keep connector credentials outside ontologies and runtime packages in an external encrypted secret store.

Execute ObjectLogic queries and higher-order rules over governed facts. Validate AI proposals and application decisions against explicit constraints, preserve datatype information in query results and inspect rule dependencies through a deterministic rule-graph view.

Control permitted queries, commands and module changes through certificate and module-scoped authorization. OntoBroker 7 uses signed Ed25519 licences and supports AES-256-GCM protection for stored modules and snapshots, with externally managed keys.

Run in memory or use the supported embedded H2 persistence profile. Add a managed external Solr 9 service for ObjectLogic full-text search, autocomplete and bounded facets. Documented backup and offline migration procedures support controlled operations and upgrades.

Use the Java 21 Administration Console, secure remote client and supported integration tools. OntoBroker 7 requires Java 21 and an .oblicense file issued for OntoBroker 7. Follow the documented procedures for migration from existing installations, including databases, encrypted modules and custom integrations. OntoStudio X is a separately versioned product.

Hybrid AI for Knowledge-Driven Systems

Why OntoBroker Powers Explainable AI

Why Hybrid AI is different

The Challenge

Most AI today is a black box. Large Language Models are powerful but opaque – they hallucinate, they can’t explain their answers, and they raise compliance concerns.

Our Solution

semafora takes a different approach. Our Hybrid AI platform fuses LLMs with symbolic reasoning. This means free text is understood in context – and every output is translated into explainable, rule-based logic.

Your Advantage

Powerful AI you can actually trust, because every step is verifiable and compliant by design.

✦ Process

How it works

1
Connect

Connect your application through the secure Java client and mutual TLS. Certificates govern permitted queries, commands and access to ontology modules.

2
Model

Represent domain knowledge, facts, constraints and higher-order rules in ObjectLogic. Import and update governed ontology modules through supported interfaces.

3
Query

Execute ObjectLogic queries and return typed results to your application. Inspect rule dependencies and validate conclusions against explicit facts and rules.

4
Automate

Integrate governed decisions into enterprise workflows through supported SQL, REST/JSON and SOAP/WSDL connectors. Keep connector credentials in an external encrypted secret store.

Feature Updates
