Mike,

Please make a recipe! I'll beg and debase myself if I have to. As I said, you deserve a prize for having figured it all out!

Ed,

Thanks for prompt and excellent advice, as always!

Here is a revised code fragment:

public class RulesResourceFactoryImpl extends XMIResourceFactoryImpl {

public static final String RULES_100_NS_URI = "http://www.ibm.com/vce/1.0.0/rules";;
public static final String RULES_PLATFORM_URI = "platform:/plugin/com.ibm.adt.vce.rules.model/model/Rules.ecore";
public static final String RULES_100_PLATFORM_URI = "platform:/plugin/com.ibm.adt.vce.rules.model/model/Rules100_2_Rules.ecore2xml";


private ExtendedMetaData extendedMetaData;
/* (non-Javadoc)
* @see org.eclipse.emf.ecore.resource.impl.ResourceFactoryImpl#createResource(org.eclipse.emf.common.util.URI) 

     */
    public Resource createResource(URI uri) {
        XMIResource resource = (XMIResource) super.createResource(uri);

        Map defaultLoadOptions = resource.getDefaultLoadOptions();
        defaultLoadOptions.put(XMLResource.OPTION_EXTENDED_META_DATA,
                getExtendedMetaData());
        defaultLoadOptions.put(XMLResource.OPTION_RECORD_UNKNOWN_FEATURE,
                Boolean.TRUE);
        defaultLoadOptions.put(XMLResource.OPTION_RESOURCE_HANDLER,
                new RulesResourceHandler());
        return resource;
    }

private ExtendedMetaData getExtendedMetaData() {
if(extendedMetaData == null) {
ResourceSet resourceSet = new ResourceSetImpl();
EPackage.Registry ePackageRegistry = resourceSet.getPackageRegistry();
ePackageRegistry.put(RULES_100_NS_URI, RulesPackage.eINSTANCE);
ePackageRegistry.put(RULES_PLATFORM_URI, RulesPackage.eINSTANCE);
resourceSet.setPackageRegistry(ePackageRegistry);
Ecore2XMLRegistry ecore2xmlRegistry = new Ecore2XMLRegistryImpl(Ecore2XMLRegistry.INSTANCE);
ecore2xmlRegistry.put(RULES_100_NS_URI,
EcoreUtil.getObjectByType(
resourceSet.getResource(URI.createURI(RULES_100_PLATFORM_URI),
true).getContents(),
Ecore2XMLPackage.Literals.XML_MAP));
extendedMetaData = new Ecore2XMLExtendedMetaData(EPackage.Registry.INSTANCE, ecore2xmlRegistry); }
return extendedMetaData;
}
}

If this passes muster, I can consider making a recipe of it. I found it
distressingly hard to get this far by reading the various newsgroup articles and
the EclipseCon 2006 slides.

Thanks again,
Mike
