UML2 is an EMF-based implementation of the Unified Modeling Language (UML^TM) 2.x OMG metamodel for the Eclipse platform.

The objectives of the UML2 component are to provide

• a useable implementation of the UML metamodel to support the development of modeling tools
• a common XMI schema to facilitate interchange of semantic models
• test cases as a means of validating the specification
• validation rules as a means of defining and enforcing levels of compliance
