Question

I am evaluating a tool which says that it supports UML 2.2. However if I search on internet, I can’t find what incremental change has occured between two version.

And yes, I tried to go through OMG documents, but those are too dense to read. Is there a simple explanation anywhere?

Answer 1

I don’t think there’s a clear overview of the changes in 2.2. There’s a UML 2.2 specification document with change bars: it marks the changed sections as opposed to version 2.1.2. It’s really the best way to view those changes – again, there’s no real overview, at least none that I could find. You can view the document (PDF) here.

I’ve skimmed the document a bit. They’re mostly minor changes. Some of the changes I came across you can quickly find in:

• 8.3 (Class Descriptions)
• 8.3.2 (ComponentRealization)
• 10.2 (Deployments – Abstract Syntax)
• 11.2 (Abstract Syntax)
• 11.3.12 (ClearStructuralFeatureAction)
• 11.3.19 (InputPin)
• 11.3.33 (ReadLinkAction)
• 11.3.47 (StartObjectBehaviorAction)
• 11.3.55 (WriteStructuralFeatureAction)
• 15.2 (State Machines – Abstract syntax)
