Semantic v Notation Model [message #76653]

Hello folks,

Sorry if this has been asked before but I have had a search and cannot find
the answer.

I have a model which essentially contains blocks of different types which
can be connected together.
The diagram is to have a very fixed (grid like) layout.
We have a prototype put together in which we have ContainerBlocks.
So an InputBlock can only be created in an InputBlockContainer etc.

The problem is that InputBlockContainer has no semantic and so we want to
move this (and other such objects) out of the semantic EMF model. But we do
need to persist the objects and their notation info.

So should I have 2 EMF models - semantic and notation ?
Or is there another way to do this which I am missing completely ?

Thanks a lot.

Hi,

I'm not sure if that bug describes the same situation I am talking about.

What I am saying is that I want to have a notation (visual) only object
and asking how do I do this.

Does the fact that it does not appear in my .ecore model have knock-on
effects ?

For example at the moment the Container is linked to the Block in the
mapping file.
This means only LogicBlock in LogicContainer for example.

How do I do this if Container isn't in semantic model ?

Thanks.

If a view doesn't correspond to some semantic element in your model you
can still accommodated in GMF using specialization types of the null type.
You can read more about it in the gmf tutorial.

Ok maybe I'm missing something but I had a look at the tutorials and I can't
see any mention of it.
Is it in 1, 2, 3 or 4 ?

Maybe you meant the developer guidelines in the help ?
If so could you be more specific as again I had a look and couldn't find
what you were referring to ?

Thanks a lot.
