What are ontologies used for?
Ontologies describe concepts, relationships and rules in a domain. They make business knowledge explicit and reusable, so applications can derive conclusions from connected facts and explain how those conclusions follow.
What is OntoBroker 7?
OntoBroker 7 is semafora’s commercially available enterprise ObjectLogic reasoner. It evaluates governed facts and higher-order rules to support active ontologies, explainable decisions and enterprise workflows.
What determines reasoning performance?
Performance depends on the ontology, rules, queries, data volume and deployment profile. Evaluate representative workloads and size the Java 21 runtime, memory and persistence configuration for your application.
What does OntoBroker 7 require?
OntoBroker 7 requires Java 21 and a signed .oblicense file issued for OntoBroker 7. Consult the support matrix supplied with your release package for supported operating systems and deployment profiles.
How do I install and configure it?
Follow the installation guide supplied with your OntoBroker 7 package. Configure the licence trust material, runtime, data locations and secure remote access for your environment. Keep private keys and credentials outside ontology modules and runtime packages.
Where do I obtain a licence or assistance?
Contact semafora@semafora-systems.com for commercial licensing, documentation and deployment support.
How do I migrate an existing installation?
Plan a controlled migration and retain backups of data, ontology modules and configuration. Follow the documented offline database migration and authorized conversion procedures for encrypted modules and snapshots. Validate custom plugins, connectors and client applications before switching production use.
What should I retain before removing an installation?
Preserve the data, modules, configuration, licences and externally managed keys needed for recovery. Follow the removal procedure for your deployment and release package.
Is OntoStudio X included?
OntoStudio X is a separately versioned product. Contact semafora to confirm compatibility for your intended installation.
Which knowledge language does OntoBroker 7 use?
ObjectLogic is the foundation of OntoBroker 7. Use it to represent facts, relationships, constraints and higher-order rules as active ontologies.
How does this support explainable decisions?
Explicit facts and rules let applications inspect the knowledge behind a conclusion and validate proposed decisions against domain constraints. A deterministic rule-graph view helps inspect rule dependencies.
How should I choose an ontology approach?
Different modelling approaches serve different purposes. Choose the language and reasoning assumptions that fit your domain, data completeness and required decisions. semafora can help assess how to model your requirements in ObjectLogic.
How do applications connect to OntoBroker 7?
Use the secure Java 21 client with mutual TLS and certificate-governed authorization. Access to queries, commands and ontology modules can be scoped to the application.
Which enterprise connectors are available?
Use supported relational access and bounded REST/JSON and SOAP/WSDL connectors. Store connector credentials in an external encrypted secret store.
How are knowledge and search data stored?
Supported operational profiles include in-memory operation and embedded H2 persistence. A managed external Solr 9 service can provide ObjectLogic full-text search, autocomplete and bounded facets. Modules and snapshots can use AES-256-GCM protection with externally managed keys.
