The SysML notation - UMD

Chapter 5 The SysML notationWords are but symbols for the relationsof things to one another and to us;nowhere do they touch upon absolute Nietzsche (1844 1900) IntroductionThis chapter describes the nine SysML diagrams. Following this introduction, theterminology used throughout the chapter is explained and the structure of SysMLdiagrams is discussed. This is followed by a discussion ofstereotypesand then ofthe SysML meta-model, which forms the basis of this chapter. Following this, eachof the nine diagrams is described in turn. For each diagram type there is a briefintroduction, a discussion of the diagram elements through its meta-model andnotation, examples of how to use the diagram and a Diagram orderingSo far, we have looked at two of the diagrams in some detail whenblock definitiondiagramsandstate machine diagramswere used to illustrate structural andbehavioural modelling in Chapter 4; these diagrams are shown again in this chapterfor the sake of completeness and also to introduce the meta-model using diagramsthat are already well chapter first covers thestructural diagramsand then thebehaviouraldiagrams.

SysML itself is defined using stereotypes on the underlying unified modelling language (UML). Stereotypes are discussed in Section 5.3. 5.2.1 Frames Any SysML diagram must have a graphic node known as a frame that encapsulates the diagram in order to make identification of, and navigation between, diagrams simpler. Frames have a defined format.
