The OMG has adopted a standard way to capture timeliness, performance, and schedulability properties of real-time systems. This profile doesn't invent any new techniques, but rather codifies what people were already doing when capturing timeliness and related properties. The profile uses stereotypes, tagged values, and constraints with specific names. The primary benefit is the ability to exchange timeliness properties among different tools, such as UML modeling tools and schedulability analysis tools.
