"Systems Engineering with SysML/UML: Modeling, Analysis, Design"

It is popular in the automotive and aviation domains. The
central model in STATEMATE are state machines. It is based on the seminal work
by David Harel, cofounder of I-Logix [22].
STATEMATE had been developed before UML emerged. I-Logix used UML to
publish the Rhapsody modeling tool that features a large number of STATEMATE
functions. Rhapsody is also a SysML modeling tool. I-Logix was taken over by
Telelogic in 2006.
1.4.8 Step
STEP describes a series of ISO 10303 standards and stands for Standard for the
Exchange of Product model data . It is a sort of building kit, consisting of several
documents, including:
?–  the EXPRESS language for describing object-oriented data models.
?–  implementation methods for realizing data models, e.g., a text format (ISO
10303-21), an XML format (ISO 10303-28), or an API (ISO 10303-22).
?–  basic models for data classes, e.g., product identifi cation and product confi guration
(ISO 10303-41), visual representation (ISO 10303-46), or mathematical
descriptions (ISO 10303-51).
?–  application models that extend the basic models, e.
