[emf-dev] Transforming Artifacts from One EPackage Version to Another

 Hi All,
 
I am working on developing a way for us to open different versions of resources that have been saved in different versions of the EPackage/schema. I was wondering if there are any EMF Resource technologies that I could use beyond the ExtendedMetaData and RecordUnknownFeature load options to actually map EClasses/EStructuralFeatures to their appropriate counterparts in the current version of the EPackage?
 
Failing that, are there any mapping/transformation frameworks that could be used to transform a resource from one version of an EPackage to another version? I have briefly heard about the org.eclipse.emf.mapping package. Is this the sort of use that this package was created to address?
 
Thanks,
Chris McGee
