Karlsruhe, Germany, 6 June 2011 | ontoprise GmbH from Karlsruhe, Germany, announced today the new releases of OntoBroker 6.1 and OntoStudio 3.1. The ontoprise product suite is the most complete SemanticWeb infrastructure and the only one in the world that supports all of the major W3C SemanticWeb recommendations including OWL, RDF(s), RIF and ObjectLogic. According to the “OpenRuleBench” benchmark, this year OntoBroker is once again clearly the leading rule and ontology engine regarding the evaluation performance. Compared to the previous OntoBroker version, the evaluation performance has been heavily improved again.

OntoBroker 6.1: Multi-Core Scalability and Performance

The independent “OpenRuleBench” benchmark (see http://rulebench.projects.semwebcentral.org) again confirms OntoBroker’s outstanding performance and scalability, which allows huge and complex ontologies to be used. OntoBroker 6.1 further improves performance and scalability by leveraging modern multicore hardware.

Another major focus for performance improvements is the semantic information integration. OntoBroker 6.1 provides a flexible, high-performance cache for accessing remote data sources (e.g. LOD or relational databases).

When using the new compact binary knowledge base snapshot feature of OntoBroker 6.1, the loading time of the ontologies may be twice as fast as before.

Support for Linked Open Data (LOD)

Many data sources available in the WWW are published as Linked Open Data (LOD). OntoBroker 6.1 provides full support for integrating LOD data sources with easy-to-use SPARQL connectors.

Furthermore, OntoBroker can be used as a server for LOD. The OntoBroker server can be started as a SPARQL endpoint which can be easily accessed using standard SPARQL queries. The endpoint also supports SPARQL UPDATE which allows the data to be loaded, updated, and modified.

Security

OntoBroker provides a strong and flexible role-based security model which can be extended by rules. In OntoBroker 6.1, the security model was further extended and it is now permitted to restrict access on properties.

 
OntoStudio 3.1: An Industry Proven Ontology Modeling Environment

The two main features of the latest OntoStudio release are the harmonization of the ontology language editing perspective and an integrated versioning component based on WebDAV. In former OntoStudio releases, there were separate modeling perspectives for each modeling language. With only one modeling perspective for all languages, it’s much easier for users to create and maintain ontologies. An additional versioning component based on WebDAV also supports users by developing ontologies via ontology check-in and check-out.

Additional OntoStudio 3.1 improvements:

• Extending existing DB schema imports with additional tables and columns
• Improved graphical mapping tool for integrating ontologies and external data sources more easily
• Improved navigation between all ontology entities
• Performance improvements for handling ontologies (especially ontologies with large rule sets)
