Can I modify the standard UML types?

[Jayson]

Ok, so I am in the midst of creating an MDG where I intend mixing standard UML with a relatively small handful of new stereotypes.

However, I would like to modify the behaviour of a number the standard UML elements (tagged values, properties & shape scripts):

1. Without having to define completely different stereotypes.
2. And have the existing toolboxes that come native with UML keep working.

That is, I would like the users to be able to create a standard UML diagram, drag elements onto that diagram as per normal but have those elements appear with extra tagged values, shape scripts and properties.

It seems like the Profile Generalize relationship might do this, but I can't seem to figure out how.

Any help is appreciated.

Cheers :-)

I think you got it wrong. Your MDG shall fake another profile (the default UML) and pretend it's still UML. That's just the wrong approach. If you extend any profile you have a new one.

Ok, so I need to create a whole new set of diagrams that reference my extended elements instead?

Notwithstanding the fact that it might be the wrong approach, I think it is technically possible (at least with existing stereotypes such as the ones from ArchiMate)

I'm not sure if this also applies to the the default UML types.

The simplest approach to achieve what you want is to use a template package
