Metamodels composition strategy for the model driven engineering context

In Model Driven Engineering (MDE) approaches, metamodelers usually need to create a metamodel based on existing metamodels, where each one abstracts a specific domain, in order to abstract a new domain, which includes elements that could be taken from the other already created metamodels. This kind of constructions allows getting advantage of the knowledge obtained in the construction of the previous built metamodels. This paper presents a proposal to solve metamodel composition through a Domain Specific Language (DSL). This DSL is used by metamodelers, who are the people that know the domains abstracted by the different metamodels and know how to combine those metamodels in order to generate the new one. Moreover, a simple case study is presented so as to demonstrate the low level of complexity of the DSL.
