Ontology-Based Metamodelling, Modelling and Application Development

Using three dimensions of the knowledge space for conceptual modeling, graphical models and logic-based ontologies are compared. Their integration results in ontology-based modelling and metamodeling. Models can be easily created and understood by humans. At the same time, the representation as an ontology allows for machine interpretation. It is shown how ontology-based metamodelling can overcome disadvantages of the Meta Object Facility and the Model-driven Architecture for application development, knowledge-based systems, model validation and knowledge management.
