Metamodels in action: An overview

This paper strives for demonstrating “metamodels in action” which means showing concrete applications of this concept. Based on a literature survey we develop a taxonomy that helps classifying existing application scenarios concerning the dimensions of domain, design, and integration and briefly describe some of the existing work we came across. Furthermore, we provide an insight into the area of semantic integration and how metamodels can be brought together with ontologies in this context. The paper is concluded with an outlook on important future work in the field of metamodeling.
