XSD to Ecore: Prevent generation of w3 schemas [message #1070696]

Hello,

I have a xsd file, which I want to migrate to Ecore. Works fine so far, but it always creates models for http://www.w3.org/XML/2001/schema and http://www.w3.org/XML/1998/namespace.

!ENTRY org.eclipse.emf.ecore 2 0 2013-07-18 15:41:28.047
!MESSAGE Both 'ProcessAnalyzerModel' and 'org.eclipse.emf.ecore' register a package for 'http://www.w3.org/XML/1998/namespace'

Is there no way to say Ecore, that it should use the given one from org.eclipse.emf.ecore?

<schema xmlns="http://www.w3.org/2001/XMLSchema"
    xmlns:xsd="http://www.w3.org/2001/XMLSchema"
    xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"

    targetNamespace="http://xmlns.deort.com/wb/process/2003"
    elementFormDefault="qualified">

    <import namespace="http://www.w3.org/2001/XMLSchema"/>

Does it import the schema for schemas?

That's quite commonly imported and we have a generated model for that...

The last page of the wizard gives you the opportunity to specify
existing models for the models needed by your schema-based model, so
there you can tell it to reuse the one from org.eclipse.emf.ecore. The
use of the schema for schemas is more problematic. Yes, we have an
Ecore model for XML Schema but it's highly specialized to deal with both
the syntactic and semantic model and isn't designed to be reusable as
something that contained be within other models...

Hello Ed,

as you told I tried it and I can reuse the provided namespace model.
For the schema there is no option, so I have to generate it. If it makes so much trouble, I will better use the generated one.
I hoped perhaps there are given one. Smile

Why? What's the problem?

You definitely should be able to reuse the namespace model so if that
doesn't work, I would need to understand why, e.g., a sample schema that
demonstrates the problem.

Okay I think we are talking past each other. I haven't noticed the possibility to import the given emf namespace model.
But after you mentioned it, I found the option.

I have imported schemas as you recommended. Smile

John,

It's very uncommon that the schema for schemas would be imported. Using
XML Schema types don't requiring importing the schemas for schema's
itself. The XML namespace schema is quite commonly imported, which is
why we have a reusable generated model for it.
