Is XSD2Ecore able to handle *.xsd files with multiple depedencies ? [message #76028]

Hi!

I used XSD2Ecore to create *.ecore files out of *.xsds.

Concretely these:
XMLSchema.xsd (http://www.w3.org/2001/XMLSchema)
WSDL.xsd (http://schemas.xmlsoap.org/wsdl/)
SOAP.xsd (http://schemas.xmlsoap.org/wsdl/soap/)

These are the official W3C files, I did not alter them in any way.

WSDL.xsd is using elments of XMLSchema.xsd.
SOAP.xsd is using elements of both, XMLSchema.xsd and WSDL.xsd.

Now here comes the problem: when converting WSDL.xsd to ecore no
XMLSchema.ecore is required. The same happens, when I convert SOAP.xsd
to ecore. Like expected I have to specify the WSDL.ecore. But I dont
have to specify the XMLSchema.ecore.

Like I said, WSDL.xsd and SOAP.xsd use several elements from XMLSchema.xsd
but when I want to generate the ecore file, I dont have to specify the
appropriate XMLSchema.ecore. Why not ? Is it even possible to generate
an ecore file for a *.xsd file which is depedent on more then one other
*.xsd
file ?

Thanks in advance,
Tim

Neither of these schemas import XMLSchema.xsd so they don't depend on that.

Maybe I'm missing something, but I just don't see imports.

Can you point out specifically an example of what you mean?

Keep in mind that XMLTypedPackage provides all the built-in types for
XML Schema, so if you're just using built-in types, you don't need an
Ecore build for that because there's a built-in model/package for it.

Hi,

I think I used the word "depend" wrong :)

What I meant is, that all the files declare namepaces,
to use elements which they don't define by themselves.

Exaple:

>SOAP.xsd
>
>xmlns:xs="http://www.w3.org/2001/XMLSchema
>xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/
>...
><xs:extension base="wsdl:tExtensibilityElement" >

SOAP.xsd uses elements from the namespaces of the XMLSchema and WSDL.
In this case "extension", which is originally from XMLSchema.xsd
and "tExtensibilityElement", which is part of the WSDL.xsd.

So I would expect, when I convert the SOAP.xsd to *.ecore, that
the resulting *.ecore has references to the appropiate metamodels,
in which the elements are, it uses.

But instead the obove example creates an "Extended Meta Data" Element,
which has no references or indicators, that this element is part
of another metamodel.

Thanks for your help,
Tim
