+====== Systems Modeling Language (SysML) ======
+[[dido:99_annexes:annex-b-terms-and-definitions:start|Go up to Terms and Definitions]]
+===== Discussion =====
+The Systems Modeling Language (SysML) is a general-purpose modeling language for systems engineering. Systems engineers use SysML to represent multiple aspects of a system within an integrated model.
+SysML supports the representation of concerns such as:
+Requirements
+System structure
+System behavior
+Interfaces
+Constraints
+Quantitative relationships
+Analysis cases
+Verification cases
+Relationships among system elements
+SysML supports model-based systems engineering by enabling architects and engineers to express system concerns through formally defined modeling constructs rather than relying only on independent diagrams and narrative descriptions.
+The term SysML may refer to the language family as a whole. SysML versions 1 and 2 represent distinct major generations of the language. SysML v1 was developed from a profile of UML. SysML v2 defines a substantially redesigned language with its own textual and graphical concrete syntaxes and a more precise semantic foundation.
+===== Definition =====
+//General-purpose modeling language for specifying, analyzing, designing, and verifying systems.//
+===== Source =====
+  * Object Management Group, Systems Modeling Language version 1.7, https://www.omg.org/spec/SysML/1.7/
+  * ISO/IEC 19514, Information technology — Object Management Group Systems Modeling Language
+  * Object Management Group, Systems Modeling Language version 2.0, https://www.omg.org/spec/SysML/2.0/
+===== Note =====
+A SysML model is not an implementation of the system it represents. The model expresses selected structural, behavioral, requirements, constraints, and analytical characteristics of the system.
+The applicable SysML major version forms part of the model context. A model expressed in SysML v1 does not automatically conform to SysML v2, and a model expressed in SysML v2 does not automatically conform to SysML v1.
+===== Example =====
+A systems architect may use SysML to model the components, responsibilities, interfaces, information flows, constraints, and traceability relationships of a regulated information-processing system.
