People who speak too many languages usually don ??™ t say much in any of them.
(Peter Ustinov)
Together, the stereotypes discussed in this chapter form the SYSMOD engineering
profi le required for the SYSMOD approach discussed in this book (Chapter 2). You
will most likely introduce additional stereotypes and defi ne an individual profi le in
your own projects. Depending on the domain, such as aeronautics, for example, and
the development process or model simulation used, each project requires its own
modeling vocabulary in the form of stereotypes and profi les. The SYSMOD profi le is
generic, forming a good starting platform for your own project-specifi c profi les.
The profi le extends the SysML language. If you want to use UML only, rather
than SysML, you have to additionally use the SysML stereotypes on which this
profi le depends. For example, the ?«domain?» stereotype is a specialization of the
SysML stereotype ?«block?» which, in turn, is an extension of the UML element class .
The UML extension mechanism for stereotypes is discussed in Section 3.
