Abstract: A computer-implemented method for converting a UML rendering of an RSM-based metamodel to a UML rendering of a MOF-based metamodel. The method includes the steps of removing inheritance from classes defined within a Repository Services Model (“RSM”) and removing each explicit “construct” operation from each class in the RSM-based metamodel Next, each use in the RSM-based metamodel of an RSM type is changed to use a non-RSM type. After this, each element of the RSM-based metamodel is converted to a corresponding MOF-based element and a determination is made as to whether or not the RSM naming service is used in the RSM-based metamodel, and if so “name” attributes are added that would have been inherited from the RSM classes. A <<metamodel>> stereotype is added to the UML rendering of the MOF-based metamodel; and the MOF properties are set on the UML rendering.
