Hi,

I have been using ATL to do M2M transformation for quite some time but only using xmi files as inputs, now i tried to use an xml file in my transformation but i have some errors.

Ok, now this is all i have done so far :

1 - i had an xml and it's xsd file
2 - from ithe xsd i generated an ecore meta model using an EMF project.
3 - i created a simple ATL transformation to another Ecore meta modèle.
4 - after execution of the ATL transformation i had some errors.

My questions are :

Can we use an xml file in an atl transformation or do we need an xmi file ?
if we need an xmi file, how do we transform an xml file to an xmi file ?

Thank you for your answers.

Hi,
You must generate some code using the genmodel then deploy the code as a plugin so that ATL can see the meta-model. You can create a plugin(s) off the editor code or else start a second target eclipse. Either way the meta-model will be registered by EMF and your ATL will be able to serialise/deserialise your models according to the XML Schema/MetaModel. See my earlier post at http://www.eclipse.org/forums/index.php?t=msg&th=203153& amp;start=0&S=6b866a5d1c59903dcc99e0e6ace7b17c
Regards,
Ronan

hi,

thank you for the response, but i still have one more question :

you said :
You must generate some code using the genmodel how can i do this ? and what is the code that is generated ?

then deploy the code as a plugin so that ATL can see the meta-model. i suppose that the response to this question is what you said in the next sentence :

You can create a plugin(s) off the editor code or else start a second target eclipse. what is the editor code ?

Thank you for your time.

Put an eye on EMF tutorial, for that purpose.

You can use the URI of the Ecore metamodel, as it is registe'red (look
at the extension in the plugin.xml.
