Hi Ed,
you told me for in the thread with the title "Load EcoreModel with
Dynamic EMF from 12'th May" that I can migrate a Datamodel in a new form
with ecore2ecore.

So I have know 2 metamodels. I create an ecore2ecore model and generate
an ecore2xml file from this.

I understood it in such a way that I must load the Datamodel in normal way
(with generated code) and save it somehow with the second model by using
the ExtendedMetaData(without using the generated code). But I don't know
how I bind the ecore2xml file in the save resource.

I uploaded my tetst Project to:

MD5: 59797168551C400F0C7C73F1160C86AF

Thanks in andvance

Süleyman,

You've looked at the EMF recipe for this?

Hi,

I found an example at http://wiki.eclipse.org/EMF/
Recipes#XMI.2FXML_Serialization_Recipes

The section what I need is "XMI/XML Serialization Recipes" right?

So if I try this example then I get an exception ""main"
java.lang.RuntimeException: Cannot create a resource for 'platform:/model/
ContainmentMapper.ecore2xml'; a registered resource factory is needed"

I made the folowing modifications the rest is the same with the example:

Namespaces:

public static final String RULES_100_NS_URI = "http://My.Model/1.0.0";
public static final String RULES_PLATFORM_URI = "platform:/model/
EA_ModelContainment.ecore";
public static final String RULES_100_PLATFORM_URI = "platform:/model/
ContainmentMapper.ecore2xml";

plugin.xml
The added entry is:

<extension
point="org.eclipse.emf.ecore.extension_parser">
<parser
class="RulesResourceFactoryImpl"
type="rules"/>
</extension>

I try to use the implementaion like this:

public void saveMofifiedModel() {
ResourceSet resourceSet = new ResourceSetImpl();
resourceSet.getResourceFactoryRegistry
().getExtensionToFactoryMap().
put(Resource.Factory.Registry.DEFAULT_EXTENSION,
new RulesResourceFactoryImpl());

File file = new File(PART1);
file.setWritable(true);
URI fileURI = URI.createFileURI(file.getAbsolutePath());

// Create a resource for this file.
Resource resource = resourceSet.createResource(fileURI);

resourceList = resource.getContents();
resourceList.add(sys);

try {
resource.save(saveOptions);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

}

Thanks in advance
