EMF Ecore output xmi, can have only text content element ? [message #1002405]

my ecore model like (simplified);

<eClassifiers xsi:type="ecore:EClass" name="IClafer" eSuperTypes="#//IElement">
<eStructuralFeatures xsi:type="ecore:EAttribute" name="isAbstract" lowerBound="1"
eType="ecore:EDataType ...XMLType#//Boolean"
unsettable="true">
</eStructuralFeatures>
</eClassifiers>

my dynamic instance from this model look like;

<?xml version="1.0" encoding="ASCII"?>
<ir:IModule>
<declaration
xsi:type="ir:IClafer">
<isAbstract
value="true"/>
</declaration>
</ir:IModule>

but i want this xmi file (isAbstract with only text element) like;

<?xml version="1.0" encoding="ASCII"?>
<ir:IModule>
<declaration
xsi:type="ir:IClafer">
<isAbstract>false<isAbstract>
</declaration>
</ir:IModule>

So how should I create my eCore file ? (i try all posibility but cant find how can i do)

I don't think EMF would produce such a serialization. Where's the XMI
declaration? The isAbstract feature would serialize as an attribute, by
default. You must be leaving some details out of your posting...

You can influence serialization using extended meta data annotations.
Try creating a schema that specifies the serialization you're expecting
(or look at the Library.xsd from the XML Schema tutorial) and look at
the EAnnotations in the Ecore model generated from it.

i already create this ecore from XSD file and XSD instance XML is like;

<?xml version="1.0" encoding="ASCII"?>
<ir:IModule>
<declaration
xsi:type="ir:IClafer">
<isAbstract>false<isAbstract>
</declaration>
</ir:IModule>

as expected for me.

But when i create dynamic instance (xmi) from ecore, <isAbstract> element now become an attribute. but why ? I need isAbstract as element

U can try too
(my xsd file attached)

Serhat,

The wizard that creates a dynamic instance always creates a resource
that uses an XMI serialization. You shouldn't expect an XMI
serialization to conform to your schema. Even what you show below
doesn't conform to your schema; there's no global element called "IModule".

It's possible to work with dynamic models that conform to the schema,
but you'd need to use GenericXMLResourceFactoryImpl to create resources
for that purpose.

Why aren't you working with the generated model?

ok but i worked with generated model.

i just write these above xmls as an example for the question.

What i have done ?

ir.xsd metamodel of ir.xml

ir.ecore metamodel of IModule.xmi (which created from IModele class with create dynamic instance method)

and when i look the IModule and ir.xml models they are not consistent with eachother.

so i think metamodels not consistent too.

Well, not of the one you showed...

Any number of serializations are possible. You can use an XMI
serialization and a resource created by XMIResourceFactoryImpl can read
and write that; that's what the reflective editor uses. Or you can use
an XML serialization that conforms to your XML Schema; resources created
by your generated resource factory implementation or by
GenericResourceFactoryImpl can read and write that...

Why do you think that?

What do you want me to do with those?

Java annotations?

Note that extended meta data annotations in the model are only respected
when OPTION_EXTENDED_META_DATA is used as a load or save option in the
resource implementation. XMIResourceFactoryImpl doesn't do that by
default. Your generated resource factory does.

Ahh i understand now. I was forced to understanding u because of my little english Smile

When i run application.editor and create ir Model, i have what i expect

But any way i dont understand why dynamic instance not give that. i think i must re read your replies.

Thanks for help Smile

regards
