Hello,

I've got some metamodels conforming to MOF 1.4 (here: http://www.emn.fr/z-info/atlanmod/index.php/MDR) in order to use them like my "IN" (inputs) in the ATL transformations. But, when I use the metametamodel that you suggested described in MOF, the console shows an error. See below the error in the Eclipse 3.4 and Eclipse 3.2:

I think the metamodels I got aren't conforming to MOF you suggested me, because the elements name aren't found in the metametamodel. I also tryed to use the option "Is metamodel" in the ATL Eclipse 3.4 run configuration, but it doesn't work.

I really don't know what to do :(
Any help?

Thanks a lot.

Hi Ed Willink,

Thanks for your answer.
I have been looking for the plugin you suggested, but I couldn't find it. I tryed to use the combobox "Is metametamodel" in the ATL Eclipse run configuration, but it doesn't work :(
I just want the MOF Metamodel (metametamodel) XMI, because in my case the models are metamodels. So, the metamodel must be the metametamodel.
Thanks a lot.

Hi Andrez

The org.eclipse.qvt plugin for the M2M/QVT Declarative project has a variety of Ecore, and EMOF formats of a variety of OMG models that
form part of QVT. MOF is one of them.

Regards

Ed Willink

Hello,

Please, I want to do metamodel to metamodel ATL transformations (any kind of metamodels). So, I need to find the metametamodel, that is, MOF. Does anyone knows where can I find the MOF metametamodel?
Thanks a lot.
