About us

ODASE Ontologies is a young software company based in Brussels (Belgium). We make the leading ontology-centric platform which revolutionizes the way mission-critical applications and systems integration are designed, built, tested and deployed. ODASE, used by tier-1 customers, is gaining excellent traction on the market.

With ODASE, ontologies (OWL, RDF), extended with logic-based business rules (SWRL), define the business problem fully in the language of the business. Based on formal logics, these ontologies can be tested and debugged declaratively, during the very early phase of the software development life cycle. These ontologies then become the core of the system in production.

ODASE uses advanced software technologies such as parallel reasoning, declarative debugging, logic programming, and abstract interpretation.
