## Textual Persistence

Dear Modelers, Significant progress has been made on a specifications of textual xtUML and separately of graphics.  This note concerns the specification of textual semantic xtUML.  This spec will serve a few purposes. It specifies a full notation of structural Shlaer-Mellor textually. It specifies how models will be persisted under BridgePoint (supplanting the OOA of […]

## Model-Driven Test with TAME

At xtUML Days 2020 UK, Marc Balcer explained model-driven test case generation with TAME.

## Panda – Open Source Development

BridgePoint is Open Source Software (OSS). It is free. However, OSS is not free like “free beer”; it is more like “free puppy”. Just like a puppy, open source software requires care and maintenance. Some members of the xtUML Community contribute to BridgePoint by finding and fixing bugs, writing code for new features, and helping […]

## MC-Generated Auto-Dispose

In good Object-Oriented Programming and Modeling, instances of classes are linked through associations. This establishes a powerful interdependence within groups of related classes but makes clean-up more complex. An instance cannot simply delete itself without considering instances of other linked classes. Since associations in xtUML are explicit and captured in the model data, the disposal […]

## Diagram and Element Types

BridgePoint is a systems modeling tool with a focus on Shlaer-Mellor xtUML (Executable and Translatable UML). In addition to the executable model elements, the tool supports analysis and documentation diagrams as well. BridgePoint supports all of the UML diagram types and supports the SysML diagrams that are the common overlap.

## Color Your Model

Did you know you can add color to your model? You can color the lines or fill in the shapes. You can use color to communicate additional information. Note that classes colored in one subsystem will show up with that same color when imported into other subsystems. You can also place model elements into layers […]
