Applying UML Extensions in Modeling Software Product Line Architecture of a Distribution Services Platform

For several years the focus of our research has been product line architecture design and analysis. An important goal is to define a method for modeling software product line architecture of a distribution services platform. An essential issue is to explicitly represent variation and indicate locations for which changes are allowed in design. In this way, the diagrammatic description of the product line architecture defined by using the method helps in instantiating it for a particular product or in its evolution for future use. From the product line architecture documented diagrammatically, it is easy to detect what kind of modifications, omisABstrAct
