The original [[oldUML-B|UML-B]] where a complete project is modelled in a diagrammatic project. A separate Event-B project is then generated for verification. This provides a high degree of hiding of the Event-B models although it is still necessary to annotate the diagrams with invariants guards and actions. Beginners who are not familiar with formal modelling may prefer this version.

UML-B is a collection of diagrammatic editors for Event-B. The diagrams are used to elaborate the machine and its content with extra model features.

It adds support for class-oriented and state machine modelling but also provides visualisation of existing Event-B modelling concepts. UML-B is similar to UML but is a new notation with its own meta-model. UML-B provides tool support, including drawing tools and a translator to generate Event-B models. The tools are closely integrated with the Event-B tools so that when a drawing is saved the translator automatically generates the corresponding Event-B model. The Event-B verification tools (syntax checker and prover) then run automatically providing an immediate display of problems which are indicated on the relevant UML-B diagram element.

To start using UML-B, first enter the UML-B 'perspective' using the normal eclipse features (e.g. Window - open perspective - other). You should see a dolphin icon in the top right corner when you are in the UML-B perspective. Create a new UML-B project using the UML-B new project wizard (e.g. File - New - Project - UML-B Project). This will create a new UML-B Project and open a Package Diagram with an empty canvas ready for you to start drawing Machines and Contexts.

Upgrading to a later version of UML-B may mean that your existing models no longer match the UML-B metamodel. This will usually occur when the UML-B version number has increased in the first or second number. e.g. 0.4.x to 0.5.x.

−
Models that were created using UML-B version 0.4.x can be migrated to the current format using the built-in migration tool which is invoked by right clicking on the *.umlb model file in your UML-B project. If the model needs migrating, the tool will delete all the diagrams in the project, reformat the model file and re-create the package diagram from it. You can then re-create your other diagrams using the open diagram buttons in the properties views or pop-up menus.

UML-B provides a 'UML-like' graphical front end for Event-B. It provides various diagrammatic modelling notations and editors for creating models which are then translated into Event-B for verification. UML-B works alongside Event-B allowing the modeller to model in normal Event-B but also contribute some aspects of the model via diagrams.

Our UML-B website contains more information about installing UML-B and getting started, as well as our current research and collaborations.

UML-B is a collection of diagrammatic editors for Event-B. The diagrams are used to elaborate the machine and its content with extra model features. The diagrams may either by contained within the machine they contribute to, or can be contained in a separate UML-B model file that is linked to the machine.

  • IUMLB.png State-machine diagrams a hierarchical state-machine diagram editor which can be used to impose sequential ordering to your events. An animator is also provided to visualise the progress of the state-machine.
  • IUMLB.png Class diagrams a class diagram editor which can be used to define data entities and their relationships and to lift behaviour based on data sets.
