Metamodelling and Ontologies(

Metamodelling plays an interesting role in MDSD. Following the discussions on metamodelling in Sect. 2.2.2, this chapter presents technologies on integrating metamodelling and ontologies. On the one hand, there are metamodels for standard ontology languages, such as OWL 2. On the other hand, there have been efforts enriching standard ontology languages with metamodelling capabilities. Chapter 11 will provide further discussions on metamodelling on how it can be useful for ontology-integrated modelling.
