In multi-perspective software development, several perspectives exist presenting different views on the developed artefacts like sourcecode, architecture descriptions, requirements, and testcases. Because some perspectives handle the same data and all the data have relationships between each other, there is a strong need for synchronization of the data between different perspectives. As example, architecture descriptions like UML component and class diagrams show the main parts of the sourcecode, which results in the need for synchronization between diagrams and sourcecode.

To solve this problem, there exist two general approaches: Synthetic approaches create manually transformations for the synchronization of the data between different perspectives. Projectional approaches create an integrated metamodel (called SUMM) which describes the complete current domain (here software development) consisting of the viewpoints of all perspectives. The perspectives read and write data directly from and to one big model containing all data of all perspectives conforming to the SUMM.

This project follows the projectional SUMM approach using integrated metamodels. The problem in the area of integrated metamodels is, that there exist no approach for creating SUMMs. Therefore, this project aims at developing and validating a method for integrating single metamodels (CMMs) into one SUMM.
