A stereotype defines how an existing metaclass may be extended. It enables the use of a platform, a domain specific terminology, or a notation in place of, or in addition with, the ones used for the extended metaclass. Similar to a class, a stereotype may have properties which may be referred to as tag definitions. When a stereotype is applied to a model element, the values of the properties may be referred to as tagged values. A stereotype can extend any model element from the reference metamodel (any UML model element). For example in UML, States, Transitions, Activities, Use cases, Components, Attributes, Dependencies, etc. can all be extended with the stereotypes. The stereotypes are created as separate model elements and can be drawn in almost all diagrams. You can specify stereotype properties in the stereotype Specification window. In the same window, you can find the description of each property. Descriptions are presented in the description area of the Specification window.

Stereotype notation in diagrams use the guillemets instead of symbols «» (see the following figure). However, when editing elements in a diagram, you can still enter the stereotype names between the «» symbols.

Stereotype Notation


The following procedures describe how to work with stereotypes:



Creating a stereotype

  • Open or create the Profile Diagram. On the diagram pallet, click the Stereotype button and place it on the diagram pane.
  • In the Containment tree, select a Profile, and from the shortcut menu, select Create Element > Stereotype.

Creating stereotype with an image

To create a stereotype with an image

  1. In the stereotype's Specification window, click the Icon specification cell to edit and select an image you want to place for the stereotype by selecting an image form:

Storing Information

To store information inside an element
