A profile in the Unified Modeling Language provides a generic extension mechanism for customizing UML models for particular domains and platforms. Profiles are defined using stereotypes, tagged values, and constraints that are applied to specific model elements, such as Classes, Attributes, Operations, and Activities. A Profile is a collection of such extensions that collectively customize UML for a particular domain (e.g., aerospace, healthcare, financial) or platform (J2EE, .NET).

Examples

The UML Profile for XML is defined by David Carlson in the book "Modeling XML Applications with UML" pp. 310 and describes a set of extensions to basic UML model elements to enable accurate modeling of XSD schemas.

SysML is an OMG-standardized profile of UML that is used for system engineering applications.
