Metamodel-based transformations permit descriptions of mappings between models created using different concepts from possibly overlapping domains. This paper describes the basic algorithms used in matching metamodel constructs, and how this match is to be applied. The transformation process facilitates the reuse of models specified in one domain-specific modeling language in another context: another domain-specific modeling language. UML class diagrams are used as the language of the metamodels. The focus of the paper is on the matching and firing of transformation rules, and on finding efficient and generic algorithms. An illustrative case study is provided.
