A UML-Profile for domain specific patterns: Application to real-time

The design of Real-Time (RT) applications is a difficult task since it must take into account the specification of time-constrained data and timeconstrained transactions. The design of these applications can be facilitated through the reuse of RT design patterns that improve software quality and capture RT domain knowledge and design expertise. However, the difficulty of RT design patterns comprehension reinforces the need for a suitable design language. This language has to express concepts modeling RT features and distinguishing the commonalities and differences between RT applications. This paper presents new UML notations that take into account the design of both RT specific concepts and the variability of domain specific patterns. The UML extensions are, then, illustrated in the RT context using an example of a controller pattern.
