AADL equivelant of an UML Interface

[MSE]

What is the equivalent construct in AADL for a UML interface with attributes?

For example, given an <<interface>> Interface_A with three attributes of type uint32, would you model it as a data abstraction in AADL? Or would it be like a port group? Below is my guess.

data Interface_A

end Interface_A;

data implementation Interface_A.i

subcomponents

x: data uint32;

y: data uint32;

z: data uint32;

end Interface_A.i

+---------------------+

|    <<interface>>    |

|     Interface_A     |

+---------------------+

| +x: uint32          |

| +y: uint32          |

| +z: uint32          |

Hello,

I think your guess looks reasonable, though it's hard to pass much judgement without knowing what you want to use the AADL for. UML is, of course, good at a different set of things than AADL, so if you're trying to get AADL to do the same thing as UML it will always be a little bit awkward. That's ok, but it will be less awkward if you have a specific tool or set of requirements that you're targeting.
