Exporting multiple XSD schemas to ecore programmatically [message #1023999] Mon, 25 March 2013 16:02 Go to next message

Hi All,
I am trying to export a group of interrelated XSD schemas to ecore programmatically(in order to get an ecore annotated with proper extended metadata for XML serialization). I am using the XSDEcoreBuilder but in the resulting ecore models, the external inheritance links are lost. I tried using the XSDEcoreBuilder.generate(collection<URI>) but I also wanted to try XSDEcoreBuilder.generate(XSDSchema) but this method returns void, I didn't understand how to use it.
If anyone have any idea, it would be very helpful.

Here is my code using XSDEcoreBuilder.generate(collection<URI>):
public void exportXSDToEcore(Collection<URI> sourceXSDFilePaths_p) {

XSDEcoreBuilder xsdEcoreBuilder = new XSDEcoreBuilder();
ResourceSet resourceSet = new ResourceSetImpl();
resourceSet.getResourceFactoryRegistry().getExtensionToFactoryMap().put("xmi", new XMIResourceFactoryImpl());
resourceSet.getResourceFactoryRegistry().getExtensionToFactoryMap().put("xsd", new XSDResourceFactoryImpl());
resourceSet.getResourceFactoryRegistry().getExtensionToFactoryMap().put("genmodel", new EcoreResourceFactoryImpl());
resourceSet.getResourceFactoryRegistry().getExtensionToFactoryMap().put("ecore", new EcoreResourceFactoryImpl());

Collection<Object> eCorePackages = xsdEcoreBuilder.generate(sourceXSDFilePaths_p);
Resource resource = resourceSet.createResource(URI.createFileURI("metamodel.generated.ecore"));
for (Object element : eCorePackages) {
if (element instanceof EObject) {
resource.getContents().add((EObject) element);
}

}
try {
resource.save(null);
} catch (IOException e) {
e.printStackTrace();
}
}

What do you mean by the external inheritance links?

If you look at the implementations of these methods, you should get the
idea...

By external inheritance links, I meant inheritance links from a model element to model elements that are not in the element's XSD but in another XSD of my XSD-family.

So I obtain one ecore file with as many packages as XSD schemas but the references between them are broken, like inheritances or cross-references that become (AnySimpleType) instead of the initial type in the XSD.

The exporter framework solves all these types of problem and you're
trying to handle all these same complexities with a different
implementation. All I can suggest is you look at how this works in the
IDE and use that as a basis because I don't have the time to help you
solve these same problems a second time.

I tried to look to what the plugins are doing when we use the wizard and I have found that they were using ModelImporter in org.eclipse.emf.importer, XSDImprter in org.eclipse.xsd.ecore.importer and ModelConverter in org.eclipse.emf.converter. I am trying the code inspired from the wizard. I'll post it as soon as I get it to work.
