In Unified Modeling Language
in the field of software engineering,
a profile diagram[1]
operates at the metamodel level to show stereotypes as classes with the «stereotype» stereotype, and profiles as packages with the «profile» stereotype.[2] The extension relation (solid line with closed, filled arrowhead) indicates what metamodel element a given stereotype is extending.
History
The profile diagram did not exist in UML 1.
Other diagrams had been used to display this issue.[2]
It was introduced with UML 2 to display the usage of profiles.[1]
