Hi!
Is it possible to have an XSD model as target model?
This simple code is giving an error:
rule Formular2Schema {
from
f : GF!FGUmlLinked(
f.refImmediateComposite() = OclUndefined
)
to
s : XSD!XSDSchema (
targetNamespace <- 'test',
contents <- f.child --creating top level types
)
}
rule Fieldset2ComplexType {
from
fs : GF!FGUmlLinked(
fs.refImmediateComposite() <> OclUndefined
)
to
x : XSD!XSDComplexTypeDefinition()
}
error:

I've looked into the source and it's the following fragment which gives me an error:
newBaseTypeDefinition = xsdSchema.getSchemaForSchema().resolveComplexTypeDefinition("anyType");
It can not get SchemaForSchema. I've looked into this method, and it's implemented as:
public XSDSchema getSchemaForSchema()
{
return getSchemaForSchema(getSchemaForSchemaNamespace());
}
I've found no way to specify namespece in XSD model using ATL. Is there any fix/workaround for it, or, maybe, i'm doing it competely wrong?

Hello,
ATL works on any EMF models (i.e. EMF resources).
So if your XSD file has been previously loaded as a proper EMF resource in memory, ATL will be able to access it and transform it.
However, if you are directly loading your models from files when running your transformation, I recommend you to use models (and corresponding metamodels) serialized in XMI.
