16.8 Stereotypes, Profiles, and Tags
As with keywords, stereotypes are shown with guillemets symbols[4], such as «authorship». But, they are not keywords, which can be confusing. A stereotype represents a refinement of an existing modeling concept and is defined within a UML profile—informally, a collection of related stereotypes, tags, and constraints to specialize the use of the UML for a specific domain or platform, such as a UML profile for project management or for data modeling.
The UML predefines many stereotypes[5], such as «destroy» (used on sequence diagrams), and also allows user-defined ones. Thus, stereotypes provide an extension mechanism in the UML.
For example, Figure 16.8 shows a stereotype declaration, and its use. The stereotype declares a set of tags, using the attribute syntax. When an element (such as the Square class) is marked with a stereotype, all the tags apply to the element, and can be assigned values.
