Hi,

Could someone tell me why it is not possible to add a metamodel to a
MetamodelRegistry ?
(org.eclipse.m2m.internal.qvt.oml.emf.util.mmregistry.Metamo delRegistry)

Indeed, first time we access to this MetamodelRegistry it is loaded with
all available metamodels (using MetamodelProviders). But it is not
possible to add metamodels to this registry after that. Why? Is there Is
there a good reason for that?

Many thanks for your comments,

There's method

public void merge(MetamodelRegistry mergedRegistry) {
...
}

that can be use to alter MetamodelRegistry.

However I wonder why do you need to change MetamodelRegistry as far it's
created by IMetamodelRegistryProvider instance just in case so that
default set of models from providers is altered with additions.

I can't find this method with the current stable version (2.0.1v20090701
using galileo).

Should I switch to the development version to get it ?

Yes, this is exactly what I need to do. We adding new metamodels to
EPackage.Registry.INSTANCE. And we want to have these metamodels
available to QVT transformations.
