'''SysML''', orThe '''Systems Modeling Language''' (SysML), is a [[___domain-specific modeling]] language for [[systems engineering]]. 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 deriveddefined from, and isas an extension of, a subset of the [[Unified Modeling Language]] Version 2.1.

SysML is notable for the wide range of systems concepts it can model. These system concepts may include hardware, software, information, processes, personnel, and facilities. In an automotive application, for example, the language can be used to specify mechanical objectives and constraints such as maximum acceleration, [[curb weight]], [[air conditioning]] performance, and interior cabin [[acoustical engineering|noise management]]. It can specify electrical parameters ranging from the [[FM radio]] [[tuning sensitivity]] to the [[real-time]] response of the [[antilock brake|anti-lock braking]] control electronics. It can specify and model the [[embedded software]] used to control the on-board automotive computers. Finally, it can model the factories used to build the car, as well as the interfaces between the organizations that work in the factory. SysML does not replace the simulation tools used to model specific subsystems, but rather provides the "glue" to model the interaction between subsystems.

A notablenoteworthy innovationimprovement of SysML over the [[Unified Modeling Language|UML]] is its support for [[requirements modeling]]. During the design process, designers and users of specific sub-systems can communicate the design criteria using several alternative design formats including diagrams, tables, and tree structures. The requirements provide a checkable interface and documentation of the evolution of the system design over time.

== OMG SysML ==

The OMG is adapting and adopting a version of SysML which it calls '''OMG SysML'''. Since the OMG adapted and voted upon a version of the SysML specification that included an open source license for distribution and use, OMG SysML is also subject to an open source license for distribution and use. The OMG SysML Specification v. 1.0 is the final adopted specification, <ref>[http://www.omg.org/docs/ptc/06-05-04.pdf OMG document ptc/06-05-04]</ref>, and is following the OMG technology adoption process.
