UML-B provides a 'UML-like' graphical front end for Event-B. 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.
A simple tutorial, showing how to construct a UML-B model.
More detail about the various diagram types.
FAQ
Migrating old UML-B models to the latest format
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.
Models that were created using UML-B versions prior to 0.4.0 can not be migrated to the latest format and should be re-entered.
