Derived feature support

The EMF metamodel for UML 2 contains several derived features which are not supported in VIATRA patterns by default. This optional integration component provides support for them via defining appropriate surrogate queries.

  • Install the feature UML Support for VIATRA from the VIATRA update site.

  • Add the org.eclipse.viatra.integration.uml plugin to your dependencies.

  • Now you can use most of the derived features like every other feature.

Static profile support

If you have an EMF-UML profile, you can query over applications of its stereotypes and their tagged values as if they were ordinary EClasses and EAttributes. As of 1.1.0, VIATRA only supports static profiles, so you have to define one as described in this blog post.

On the example below continuing the blog post, in the started runtime Eclipse, we created a pattern that matches ExampleStereotype applications, and as we can see in the Query Explorer, it has matches on a simple UML instance model:


Note for Papyrus users: it is recommended to also register your profile with Papyrus. To accomplish this, add an extension for the org.eclipse.papyrus.uml.extensionpoints.UMLProfile extension point, pointing to the UML model file containing your profile. For more information, refer to this thread.

The code for this example can be found in this repository.
