OWL + Metamodel: Model Bridge

Model bridges connect software models and ontologies on the modeling layer M1. They are de fined in the metamodeling layer M2 between diff erent metamodels. The figure below exemplifies a model bridge.

Model Bridge

Integration bridges merge information of the models from the software modeling and from the ontology space. This allows the building of integrated models (on modeling layer M1) using constructs of both modeling languages in a combined way, e.g. to integrate UML class diagrams and OWL.

A transformation bridge describes a (physical) transformation between models in layer M1. The models are kept separately in both modeling spaces. The information is moved from one model to the model in the other modeling space according to the transformation bridge.
