Hi everyone,
I have created my own DSL and I want to transform the model written in my
new DSL into something else by using M2M transformation with ATL. I know
it sounds weird but it is part of my diploma thesis and there it makes
perfect sense :)
Is it possible to get my model as XMI/ecore file (without writing my own
generator) so I can use it in ATL as input for my transformation?
Or else, what would you recommend how I could hook up a M2M transformation
to Xtext?
Best regards,
Adalbert

Hi,
We are also using TMF and ATL for M2M transformation, in our research as
well as in a masters project of one of our students. I don't think it's
weird :-P.
I just tried to use a TMF generated ecore metamodel and a file created
with the TMF editor as an instance, and I got the following error:
"Error loading platform:/resource/ProjectAToTree/ATL/projectA.pa:
org.xml.sax.SAXParseException: Content is not allowed in prolog."
Then we tried Adalbert's solution, transforming the file into xmi, and
then ATL worked without problems.
For information, this transformation is very simple if you created a
generator project: just find the .mwe workflow and replace the component
"org.eclipse.xpand2.Generator" with:
<component class="org.eclipse.emf.mwe.utils.Writer">
<uri value="./your path here/your file name here.xmi" />
<modelSlot value="model" />
</component>
Running the generator workflow should produce your xmi file.
If we can avoid the latest step it will be nice (and our masters student
will probably be relieved!).
Regards,
Alexis

Hi Alexis,
is there a way to specify the EMF resource factories that are available
in the transformation engine? The error message indicates a missing
resource factory for the 'pa' file extension.

Sebastian

Hi Sebastian,
AFAIK this is possible using Ant to launch ATL, but I just spent a
couple of hours trying without result, probably because I'm a complete
noob using ATL.
Of course, if there is an MWE component to do this like Krzysztof says,
everything will be more simple. But in our case the xmi translation
works just fine.
Regards,
Alexis
