Extending SysML Stereotype in Profile

[Michael Schneider]

Hi, I would like to create an extension of a SysML stereotype in a profile. I tried to use generalization to do so (as specified in the SysML specification). I used SysML1.1::block as the stereotype I want to specialize. However, that doesn't work. What do I need to do, to achieve this? I know, I could extend the Class metaclass and then later apply my new stereotype to a block, but a) it would have both stereotypes then and b) this is cumbersome. Any ideas?

Thanks,
Michael

Still no solution for this one? Any idea anybody?

Thx,

Michael,

I don't know much about profiles and stuff, but IIRC you cannot extend existing profiles if you don't have the EA (meta) model.

Hi Geert,

well, in theory I should be able to formally import the SysML profile and then use generalization on the SysML stereotypes. That's at least what the SysML specification states. However I have no idea how to do that in EA.

That's the problem, EA doesn't really like meta-models from omg, and I don't think its "profiles" are really standard.

I once was able to (sort of) import the UML meta-model into EA by first importing the meta-xmi file into StarUML first and then exporting back to xmi and importing that into EA. (resulting model is available on the community site)

You might be able to do something similar for SysML, but if/how to make this model into a profile... I have no idea.

I'm afraid this is what you will need to do. And yes it will, correctly, have both stereotypes.
