The emerging real-time standard [UML]

We describe the objectives, rationale and content of the newly proposed real-time Unified Modeling Language (UML) profile standard for the Object Management Group (OMG). The intent of this profile is to enable the inclusion of quantitative temporal information into UML models so that they can be analyzed for key time-related properties such as schedulability and performance. The primary purpose of the paper is to solicit feedback from real-time domain experts prior to formal adoption of the standard.
