Stereotypes are used to create new model elements, as extensions of Stereotypes are used to create new model elements, as extensions of UML metaclasses. In a class diagram, the name of a stereotype is UML metaclasses. In a class diagram, the name of a stereotype is shown within a pair of guillemets (e.g. <<stereotype>>) above the shown within a pair of guillemets (e.g. <<stereotype>>) above the class name. class name.

ConclusionConclusion

This short paper describes the two UML profiles that we use for the This short paper describes the two UML profiles that we use for the definition of a specification-to-design mapping in the context of the definition of a specification-to-design mapping in the context of the OMG SWRadio standardization effort. OMG SWRadio standardization effort.

We also introduce the concept of UML model mapping and outline the We also introduce the concept of UML model mapping and outline the mapping we defined between the UML RRRT Design profile and the mapping we defined between the UML RRRT Design profile and the UML Spec profile. This mapping allows making the transition between UML Spec profile. This mapping allows making the transition between a UML spec and a UML RRRT Design in a systematic and traceable a UML spec and a UML RRRT Design in a systematic and traceable manner. manner.
