Assumptions that are made are often not communicated, or are inconsistent between the artifacts and the system architecture. Inconsistencies arise when communicating the content of these artifacts with other teams and sometimes among different team members within the same teams.
The aspects include topology and organizational diagrams, tables, reports, and other documents that capture parts of a single system design. Projected views are described in specific block diagrams, tables, reports, and other documentation.Ĭurrent system design practice is driven by loosely coupled documents of different aspects of the system that are created by different teams at various levels of detail. The plug-in manages consistency between models of the flight system architecture and projected views from the set of defined architecture models, and allows for annotating semantics by creating and applying metamodels that capture domain-specific concepts using the profiling mechanism in Magic-Draw. These fundamental constructs are annotated by ontologies to provide semantics and context for architecture models at each level of abstraction. Each level of abstraction is characterized by a model of components, interfaces, signals, and channels. The CAESAR software is a plug-in for No Magic's MagicDraw tool that allows users to capture a model of a flight system architecture at various levels of abstraction while maintaining consistency of the system design information, products, and artifacts that are commonly used in flight system design such as block diagrams that capture the system topology.
