Lorenzo,

Loading resources works the same for all models and that's described in
the introductory overview. The paper about dynamic Ecore will probably
be very helpful for what you want to do.

I'm doing something like this, does it look right?

ResourceSet resourceSet = new ResourceSetImpl();

resourceSet
.getResourceFactoryRegistry()
.getContentTypeToFactoryMap()
.put(EcorePackage.eCONTENT_TYPE, new
EcoreResourceFactoryImpl());

resourceSet
.getURIConverter()
.getContentHandlers()
.add(new RootXMLContentHandlerImpl(EcorePackage.eCONTENT_TYPE,
null, null,
EcorePackage.eNS_URI, null));

resourceSet.getPackageRegistry().put(EcorePackage.eNS_URI,
EcorePackage.eINSTANCE);

URI uri = URI.createFileURI("model/FJ.ecore");

Resource resource = resourceSet.getResource(uri, true);
System.out.println("Loaded " + uri); //$NON-NLS-1$

System.out.println("Resource: " + resource.toString());

I've not tried content handlers for Ecore.

It's best to use an absolute path.

yes, that was just a test... by the way, is there a kind of reference
sheet for the several available URI syntaxes?

Well, anything that's a well formed URL is allowed. Others define how
http:, file:, zip: are structured. The Eclipse platform defines how
platform: is structured...
