reference ecore model path of a different ecore model [message #772328]

Here is my problem.

We currently have several ecore models for our applications. One of the ecore models (mainModel.ecore) has stuff that is common in all the rest of the models. So, what i want to do is have all the other models reference the contents of that one model so we do not have to constantly copy the contents of that one model into all the models everytime there is a change.

Is this possible and how can i do this? I am very new to ecore and still do not understand a lot of the terminology.

--------------------------------------------------------------------------------

Here is what i attempted so far:

I tried "load resource..." by loading the mainModel.ecore into all the other models and deleting the local references. There were a lot of places that i had to fix after doing this and i did. After re-generating the source and trying to compile there are places where it tried accessing the "dotpath" that was local to the original file and i do not know how to change that "dotpath" to reference the "loaded resource". So it is not able to resolve those paths.

Thanks!

Here is another addition. This might actually solve my problem, if it is possible.

How do i get

EcoreUtil.getRootContainer

to return the container of the loaded resource? I need to have that location so that i can resolve certain paths from that root.

Thanks

Yes. This shows an example:

You mean replacing them with the loaded ones?

If you replaced all references, there should be nothing left to fix,
except to delete things that aren't referenced anywhere...

It sounds like your model wasn't well formed. Did it validate okay?

Ashton,

You shouldn't need to resolve paths yourself.

Yes it validated ok. But the compiling still fails in certain places where data types are not resolving.

Ashton,

Did you try the example? It's extremely common to have models that
reuse things from other models. That shouldn't cause any problems.
Unfortunately you've really not described anything concrete that I can
help you with. You'll have to show/describe something more concrete to
get further help.
