Re: [xsd-dev] XMI or XSD

[merks@xxxxxxxxxx]

Le Anh,

I'm not really sure what you are asking because installing XSD does not
replace XMI serialization with "XSD serialization."   EMF serializes a
resource as XMI by default, no matter what is installed.

 If you look at a ResourceFactory that's generated for an Ecore model
imported from XML Schema, you'll see this something like this:

   public class CameraResourceFactoryImpl extends XMLResourceFactoryImpl
   {
      /**
       * <!-- begin-user-doc -->
       * <!-- end-user-doc -->
       * @generated
       */
      protected XMLResource.XMLMap xmlMap = new XMLMapImpl();

      /**
       * Creates an instance of the resource factory.
       * <!-- begin-user-doc -->
       * <!-- end-user-doc -->
       * @generated
       */
      public CameraResourceFactoryImpl() {
            super();
      }

      /**
       * Creates an instance of the resource.
       * <!-- begin-user-doc -->
       * <!-- end-user-doc -->
       * @generated
       */
      public Resource createResource(URI uri) {
            XMLResource result = new CameraResourceImpl(uri);
            result.getDefaultSaveOptions().put(XMLResource.OPTION_XML_MAP,
   xmlMap);
            result.getDefaultLoadOptions().put(XMLResource.OPTION_XML_MAP,
   xmlMap);
            return result;
      }
   } //CameraResourceFactoryImpl

Is the presence of the XMLMap during load or save that causes EMF to
intepret the EAnnotations on the Ecore model that indicate how to serialize
according to the original XSD:

   <?xml version="1.0" encoding="ASCII"?>

   <ecore:EPackage xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI";
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";

     </eClassifiers>

Hi,

I have installed XML Schema Infoset Model in the Eclipse workbench.
Therefore, XMI serialization is replaced by XSD schema. How can I
configure for switching between XMI and XSD and to force EMF use either
a XMI or a XSD like I want?

Regards
