UML Metamodel version 1.1 1 September 1997

This is the metamodel of the Unified Modeling Language (UML). It describes the constituents of all

well-formed models that may be represented in the UML, using the UML itself. See

http://www.rational.com/uml for updates.

The metamodel is organized according to the following packages:

Foundation

Core

Auxiliary Elements

Extension Mechanisms

Model Management

Stereotypes, tagged values, and constraints are the mechanisms of extensibility in the UML. Stereotypes extend the

classes in the metamodel, tagged values extend the attributes of classes in the metamodel, and constraints extend the

semantics of the metamodel. Certain stereotypes, tagged values, and constraints are predefined in the UML; others may

be user defined.
