Hi,
I successfully generated a dynamic Ecore model from an XML Schema using
XSDEcoreBuilder, and created its instance using the generated EPackages,
by following the article below:
http://wiki.eclipse.org/index.php/Generating_Dynamic_Ecore_f rom_XML_Schema
How can I serialize the instance with xsi:schemaLocation?
I set OPTION_SCHEMA_LOCATION, but it didn't work. I also tried to set
"xSISchemaLocation" of the DynamicEObject "DocumentRoot" by the following
code, but xsi:schemaLocation did not appear.
EClass documentRootClass = (EClass)
ePackage.getEClassifier("DocumentRoot");
EObject documentRoot = EcoreUtil.create(documentRootClass);
EMap<String, String> map = (EMap<String, String>)
documentRoot.eGet(documentRootClass.getEStructuralFeature("xSISchemaLocation "));
map.put(ePackage.getNsURI(), "sample.xsd");
:
Do I have to serialize the Ecore model as .ecore file in advance?
Thanks,
Koji

I would expect the above should definitely do the trick. It does when I

When an instance document is serialized, if the EPackage's nsURI is
different from the EPackage's eResource()'s URI and the
OPTION_SCHEMA_LOCATION is mapped to Boolean.TRUE, it will automatically
serialize an xsi:schemaLocation for the nsURI -> packageResourceURI mapping.

Ed,
Thank you for your reply.

Yes, I have used OPTION_SCHEMA_LOCATION only for save.

eResource() of the EPackage generated dynamically from an XML Schema is
null. Therefore, I thought that the EPackage has to be saved as .ecore
file as stated in the EMF book.

Koji,
XSDEcoreBuilder.generateResources will generate resources for the Ecore
package's it creates and will set the URI of that resource to match the
package's nsURI. You could modify the resulting resources to set the
URI to be the original schema's location.

Ed,
XSDEcoreBuilder.generateResouces() solves my problem! Thank you for
your help!
I successfully serialized an instance document with xsi:schemaLocation
by the following experimental code:
XSDEcoreBuilder xsdEcoreBuilder = new XSDEcoreBuilder();
Collection<Resource> resources =
xsdEcoreBuilder.generateResources(schemaURI);
EPackage ePackage = null;
for (Resource resource : resources) {
if (resource instanceof XSDResourceImpl) {
// schemaURI = resource.getURI();
} else {
ePackage = (EPackage) resource.getContents().get(0);
}
}
EObject documentRoot = EcoreUtil.create((EClass) ePackage.getEClassifier("DocumentRoot"));
ResourceSet resourceSet = ePackage.eResource().getResourceSet();
Resource resource = resourceSet.createResource(URI.createURI("platform:/resource/project/sample.xml "));
resource.getContents().add(documentRoot);
ePackage.eResource().setURI(schemaURI);
Map<Object, Object> saveOptions = new HashMap<Object, Object>(1);
saveOptions.put(XMLResource.OPTION_SCHEMA_LOCATION, Boolean.TRUE);
resource.save(saveOptions);
By the way, the following article says "For these loaded Ecores to be
available, we need to register them to the global package registry.",
but I think this is incorrect. The snipet in the article registers
resourceSet's local package registry. Am I right?

Koji,
Yes the article registers them in the local package registry of the
resource set, so I've modified it to not refer to the global one.
Thanks. :-)
