A metamodel selector may determine a semantic metamodel for at least two software applications, the semantic metamodel including a description of semantics, processes, and data that are applicable to the at least two software applications. A metadata manager may determine application metadata describing an application of the at least two applications. A transformation engine may transform the application metadata into an application-specific metamodel instance of the semantic metamodel, and an integration engine may integrate the at least two software applications, based on the application-specific metamodel instance.
