What is SysML? - What You Need to Know

The SysML Forum is a web community dedicated to the Systems Modeling Language (SysML), an open standard architecture modeling language for systems engineering applications. Since SysML is a popular dialect (technically a Profile) of UML v. 2, the industry standard for specifying software-intensive architectures, it is a popular choice as a lingua franca for Model-Based Systems Engineering (MBSE) teams that include both systems and software engineers.

Here in the SysML Forum you will find information related to SysML tools, SysML training, SysML tutorials, SysML specifications, SysML compatible processes, SysML publications, and SysML discussion groups (mailing lists). You can also find information about Model-Based Systems Engineering (MBSE) approaches that use SysML as their lingua franca.

What is SysML?

The Systems Modeling Language (SysML) is a general-purpose architecture modeling language for Systems Engineering applications.
• SysML supports the specification, analysis, design, verification and validation of a broad range of systems and systems-of-systems. These systems may include hardware, software, information, processes, personnel, and facilities.
• SysML is a dialect of UML 2, and is defined as a UML 2 Profile. (A UML Profile is a UML dialect that customizes the language via three mechanisms: Stereotypes, Tagged Values, and Constraints.)
• SysML is an enabling technology for Model-Based Systems Engineering (MBSE).

The open source SysML specification is publicly available for download, and includes an open source license for distribution and use. The most recent revision of SysML adopted by the Object Management Group is OMG SysML v. 1.4. For more information about the most recent version of SysML see the SysML FAQ What is the current version of SysML?.
