text: # Ontology Definition MetaModel
  
  The Ontology Definition MetaModel (ODM) is an Object Management Group (OMG) specification to make the concepts of Model-Driven Architecture applicable to the engineering of ontologies. Hence, it links Common Logic (CL), the Web Ontology Language (OWL), and the Resource Description Framework (RDF).
  
  OWL and RDF were initially defined to provide an XML-based machine to machine interchange of metadata and semantics. ODM now integrates these into visual modeling, giving a standard well-defined process for modeling the ontology, as well as, allowing for interoperability with other modeling based on languages like UML, SysML and UPDM.
