UML Designer provides a set of common diagrams to work with UML 2.5 models.
The intent is to provide an easy way to make the transition from UML to domain specific modeling. This way users can continue to manipulate legacy UML models and start working with DSL.
Users can even re-use the provided representations and work in a total transparence on both UML and DSL models at the same time.
UML Designer is based on the UML2 Eclipse plugin. As it’s based on Sirius, the UML models could be combined with Domain Specific Modeling. Each diagram definition could be extended and adapted to specific user needs or combine it to Domain Specific Languages.
Sirius is an Eclipse project which allows you to easily create your own graphical modeling workbench by leveraging the Eclipse Modeling technologies, including EMF and GMF. It provides a generic workbench for model-based architecture engineering that could be easily tailored to fit specific needs.
UML Designer provides the most used generic UML diagrams:
- Package Hierarchy.
- Class Diagram.
- Component Diagram.
- Composite Structure Diagram.
- Deployment Diagram.
- Use Case Diagram.
- Activity Diagram.
- State Machine.
- Sequence Diagram.
- Profile Diagram.
- Uses the standard UML2 metamodel.
- Cross-platform software – runs under Linux, macOS, and Windows.
