UML provides the means to use specific variation mechanisms to describe hierarchical systems. However, it does not support a description of variation, as it is required for service architecture. UML built-in extension mechanisms refine its specification. This chapter presents the extensions of the UML for representing variations in the software product line architecture of middleware services. The product line is defined as a middleware services framework that includes several products. The products realize different functionality by using various modern software technologies of spontaneous networks. Architecture design produces descriptions at two abstraction levels from multiple viewpoints. The modeling of service architectures benefits from a more familiar and widely used notation that improves stakeholders’ understanding of the architectural artifacts. A standard based notation also enables more extensive tool support for manipulating architecture models.
