The Systems Modeling Language (SysML) is a general-purpose modeling language for systems engineering applications. It supports the specification, analysis, design, verification and validation of a broad range of systems and systems-of-systems.
SysML was originally developed by an open source specification project, and includes an open source license for distribution and use. SysML is defined as an extension of a subset of the Unified Modeling Language (UML) using UML’s profile mechanism. The language’s extensions were designed to support systems engineering activities.
For the CAC, SysML is important because it is one of the key interoperability standards supported by Comet / CDP4. It can be used to exchange modeling information with a number of other tools such as Enterprise Architect, Cameo and others.
