Hello,

I have got a problem with my Ecore meta models. I created two Ecore meta models from two xsd files describing different namespaces in XML (let's say AAA and BBB). These xsd files reference each other (or: on references elements of the other) and so do these two ecore files.

Now, I want to create an xmi file (using "Create dynamic instance" for example) which is supposed to look like this:
<?xml version="1.0" encoding="ASCII"?>
<aaa:DocumentRoot xmi:version="2.0" xmlns:xmi="http:SLASHSLASHwww.omg.org/XMI" xmlns:xsi="http:SLASHSLASHwww.w3.org/2001/XMLSchema-instance" xmlns:aaa="http:SLASHSLASHwww.aaa.org/aaa" xsi:schemaLocation="http:SLASHSLASHwww.aaa.org/aaa aaa.ecore">
  <node>
    <bbb:somethingFromBBB>xx</somethingFromBBB>
  </node>
</aaa:DocumentRoot>

Notice, that there is a namespace qualifier given for elements from the other Ecore model BBB (or xsd file).

I want this, because this xmi file to be compatible to the xsd files I initially started with. And I want to validate the xmi file.

But this is not what I get, instead I get
<?xml version="1.0" encoding="ASCII"?>
<aaa:DocumentRoot xmi:version="2.0" xmlns:xmi="http:SLASHSLASHwww.omg.org/XMI" xmlns:xsi="http:SLASHSLASHwww.w3.org/2001/XMLSchema-instance" xmlns:aaa="http:SLASHSLASHwww.aaa.org/aaa" xsi:schemaLocation="http:SLASHSLASHwww.aaa.org/aaa aaa.ecore">
  <node>
    <somethingFromBBB>xx</somethingFromBBB>
  </node>
</aaa:DocumentRoot>


The xsd files look like
aaa.xsd:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<xs:schema xmlns:xs="http:SLASHSLASHwww.w3.org/2001/XMLSchema"
	targetNamespace="http:SLASHSLASHwww.aaa.org/aaa"
	xmlns:aaa="http:SLASHSLASHwww.aaa.org/aaa"
	xmlns:bbb="http:SLASHSLASHwww.bbb.org/bbb">
		
	<xs:import namespace="http:SLASHSLASHwww.bbb.org/bbb"/>

 <xs:element name="node">
  <xs:complexType>
   <xs:choice minOccurs="0" maxOccurs="unbounded">
    <xs:element ref="bbb:something_from_BBB" />
   </xs:choice>
   </xs:complexType>
</xs:element>

 
</xs:schema>


bbb.xsd:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<xsd:schema xmlns:bbb="http:SLASHSLASHwww.bbb.org/bbb" xmlns:xsd="http:SLASHSLASHwww.w3.org/2001/XMLSchema"
	xmlns:aaa="http:SLASHSLASHwww.aaa.org/aaa"
	targetNamespace="http:SLASHSLASHwww.bbb.org/bbb"
	elementFormDefault="qualified"
  	attributeFormDefault="unqualified">
  		
<xsd:import schemaLocation="aaa.xsd" namespace="http://www.aaa.org/aaa"/>
  		
<xsd:element name="something_from_BBB" type="xsd:string"/>
	
</xsd:schema>



The options used for saving and loading are:
		result.getDefaultSaveOptions().put(XMLResource.OPTION_EXTENDED_META_DATA, Boolean.TRUE);
		result.getDefaultLoadOptions().put(XMLResource.OPTION_EXTENDED_META_DATA, Boolean.TRUE);

		result.getDefaultSaveOptions().put(XMLResource.OPTION_SCHEMA_LOCATION, Boolean.TRUE);

		result.getDefaultLoadOptions().put(XMLResource.OPTION_USE_ENCODED_ATTRIBUTE_STYLE, Boolean.TRUE);
		result.getDefaultSaveOptions().put(XMLResource.OPTION_USE_ENCODED_ATTRIBUTE_STYLE, Boolean.TRUE);

		result.getDefaultLoadOptions().put(XMLResource.OPTION_USE_LEXICAL_HANDLER, Boolean.TRUE);


What am I doing wrong? What is the right way? Is this behaviour even possible? Am I totally on the wrong track?


Thank you very much for an answer!

Best regards,
Daniel

Without an xmlns for bbb?

XMI serializations won't be compatible with the XSD. You need to use
the generated resource factory to create resources that do the proper
XML serialization. That's not supported for dynamic models.

Yes, I'd expect that from an XMI serialization.

You mentioned creating a dynamic instance. That doesn't use generated
code at all.

If you use the generated resource factory to create the resource it
should work a lot better...

Daniel,

Note that my comment about what's not supported for dynamic models
should really say that's not supported when creating dynamic instances
using the Ecore editor. It is supported for dynamic models, you but
it's clear you're using an XMIResourceImpl not an XMLResourceImpl for
the serialization to get what you've shown...
