Hi All,

I have been working with Ocl in ATL but I am just now using the Ocl
plugin in EMFT. I would like to specify some OCL "queries" using some
meta information.

1) i would like to get the container of a given EObject. Say i have
something like Writer.allInstances()->collect( w | w.eContainer() ). In
this case I would like the list of all libraries. But I would also like
to do this in a more general sense
self.eContainer().

2) I would like to do some processing on the MetaModel elements. In the
case of the library example, I would like to say
Writer.getEStructuralFeatures()

Are these possible? Should they be?

Cheers,
ian
