A Reference Structure for Modular Metamodels of Quality-Describing Domain-Specific Modeling Languages

To understand the problems in metamodeling, this work presents an investigation of bad smells in metamodels. The core contribution of this work is the reference structure. It enables design, evolution, and extension of metamodels for modeling languages used for quality analysis. Applying the reference structure yields a modular metamodel. To be able to couple the metamodel modules in a meaningful way, this book investigates metamodel extension mechanisms.
