I found the problem: we must use "/" in the paths' beginning.

I am still having problems. In the file smaple-Families.xmi, in the line 2, if I use xmlsn="Families" I get a problem:

Error loading platform:/resource/Families2Persons/sample-Families.xmi: org.eclipse.emf.ecore.xmi.PackageNotFoundException: Package with uri 'Families' not found. (platform:/resource/Families2Persons/sample-Families.xmi, 3, 27)

In order to solve this problem, I need to use xmlns="/Families2Persons/Families.ecore"

Why am I having this problem?

In Families2Persons.launch I have '<mapEntry key="Families" value="/Families2Persons/Families.ecore"/>'
In Families2Persons.atl I have '-- @path Families=/Families2Persons/Families.ecore'
