Hi,

is it possible to use an XSD as metamodel in ATL (programmatically within a Java application) or is it necessary to create an ecore from the XSD?

Regards,

Tex

I don't know if this helps you, but you can do that with QVTo. With QVTo
you can simply load an Xsd using the XsdEcoreBuilder and pass the (then
in-memory Ecore) Model to the engine.

And can I do model to model transformations with QVTo? Is it ready for production use or still in early test phases?

I want to transform my model to UML. Here I have the Eclipse UML2. Can I use QVTo for this?

Regards,

Tex

Unfortunately I am now at the same situation as before:

I have my metamodel as XSD and my instance. I want to perform the transformation from Java directly. And now the problem is: when loading the model with:

		Resource inResource = resourceSet.getResource(
				URI.createURI("samples/testfile.wsdl"), true);

I get the error:

Exception in thread "main" java.lang.RuntimeException: Cannot create a resource for 'samples/testfile.wsdl'; a registered resource factory is needed

Ok, but how to register?

		Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap().put("wsdl",
			???);

In order to load the XSD I can use:

 
		Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap().put("xsd",
			new XSDResourceFactoryImpl());

But I don't have this for my Metamodel (which is wsdl in this case, but could be something more custom). Do I have to generate the Ecore, then GenModel etc.?

Regards,

Tex

Hi

QVTo was developed by Borland and has been useable and stable for a
couple of years.

Since Borland's demise, QVTo has had limited maintenance; sufficient to
keep it in the Eclipse release train.

There are a number of parties with significant interest in QVTo so
expect observable development to pick up again in a year or so, possibly
after a minor internal API hiccough to align with and exploit Xtext and
the automated tooling for the revised UML-aligned implementation of OCL.

Today, if you like QVTo; great. If you have a problem; it's Open Source;
you can fix it or discuss the problem with others.

Contact me if you are interested in participating actively.

Regards
