I would expect you don't have to do anything special. Xtext supplies EMF resource implementation, so you should be able to consume the textual representation of your models in any context where EMF model is expected. You can verify this by opening your textual representation (say .mydsl) file via the Sample Reflective Ecore editor.

Hello,

Actualy is not that simple. To interpret your dsl files you neer to invoke the xtext MweReader and supply the generated dslStandaloneSetup class. Then you can save the interpretead model as an xmi.

<workflow>
	<property name='baseDir' value='platform:/resource/MyProject'/>
	<property name='dslFile' value='${baseDir}/dslfiles/file.mydsl'
	<property name="targetDir" value="${baseDir}/xmi"/>

	<bean class="org.eclipse.emf.mwe.utils.StandaloneSetup" platformUri=".."/>

        <component class="org.eclipse.xtext.MweReader" uri="${dslFile}">
			<register class="dslStandaloneSetup"/>
			<outputSlot value="model"/>		
        </component>

       <component class="org.eclipse.emf.mwe.utils.Writer">
			<modelSlot value="model"/>
			<uri value="${targetDir}/dsl.xmi"/>
	</component>
</workflow>

When creating your xtext project check the "create generator project" option and look at it to see how your generated class is invoked.

My current issue is trynig to invoke both this (the workflow) and the subsequent ATL (in my case epsilon) transformations in a single ant file.

thank you very much for your help.
it works, but I can not open the xmi file with sample reflective ecore model editor

I received this warning
[WARNING]: the element in slot 'model' is already contained in a resource and will be taken out of that resource!(Element: -UNKNOWN-; Reported by: Writer: Writing model to src-gen/dsl.xmi)

look at this link http://www.eclipse.org/forums/index.php?t=msg&th=164435& amp; amp;start=0&

Thank you very very much Smile
