[ATL] accessing sub-package elements in metamodels [message #1571]

Hello!

In case of having different packages and sub-packages in my metamodelo,
How to access their elements in ATL rules?

For instance, in the rule below, we can access the metaclass A contained
in the Author metamodel.

rule Author{
from a: Author!A
to p:Person!Person(...)
}

But, in case of having A as a metaclass contained in the sub-package named
P1 that in turn is contained in the Author metamodel. How I should access
the meta-element A in an ATL rule?

Thanks,
Franklin Ramalho.

In same way. There is no (still) resolution operator
in ATL for package.subpackage.etc.

I'm not sure for ATL2006.

I just added a FAQ entry about this issue:
http://wiki.eclipse.org/index.php/ATL_FAQ#How_can_I_refer_to _metamodel_classes_located_in_subpackages.2C_and_avoid_name_ collision.3F
