Information technology - Object management group systems modeling language (OMG SysML)

ISO/IEC 19514:2017 is to specify the Systems Modeling Language (SysML), a general-purpose modeling language for systems engineering. Its intent is to specify the language so that systems engineering modelers may learn to apply and use SysML; modeling tool vendors may implement and support SysML; and both can provide feedback to improve future versions. Note that a definition of "system" and "systems engineering" can be found in ISO/IEC/IEEE 15288.

SysML reuses a subset of UML 2 and provides additional extensions to satisfy the requirements of the language. This International Standard documents the language architecture in terms of the parts of UML 2 that are reused and the extensions to UML 2. The International Standard includes the concrete syntax (notation) for the complete language and specifies the extensions to UML 2. The reusable portion of the UML 2 standard is not included directly in the International Standard but is included by reference. The International Standard also provides examples of how the language can be used to solve common systems engineering problems.

SysML is designed to provide simple but powerful constructs for modeling a wide range of systems engineerin
