UML 2.4.1 now released

When UML 2.4 was released we discovered an issue that meant it was impossible to interchange StructuredActivityNodes reliably. StructuredActivityNodes are executable nodes in an activity diagram that are also groups.  UML 2.4 doesn’t specify clearly whether they should be serialized as nodes or as groups; as a consequence, different tools do different things.  In UML…

UML for mainstream developers

I’d like to explore the idea that UML could be made more useful to mainstream developers if it were redesigned so that a UML model could directly represent the semantics and terminology of modern programming languages.  For example, if you are working in C#, instead of having Attributes and Operations in your class diagram, you…

Explicit Design

Cameron has been blogging about new features in our product.. In a recent post he used the term Explicit Design.  I’ve been reflecting on this, and I like it. In software development we really do need to capture design data that is not just the code, but should be saved and versioned just like the code.  What do we…

Oslo topics

Keith Short has been blogging about Oslo and the DSL Toolkit and Oslo’s use of model-driven terminology. There’s been a fair amount of speculation about how all these things fit together, so it is good now PDC is over to be able to clarify the relationships.
