Hello,

I am new to ATL language, and I ran successfully ATL eclipse examples on eclipse.

Now, I am trying to make a M2M transformation BPMN 2.0 to SCA 1.0

I am using:

- eclipse Helios and ATL 3.1.1

- BPMN 2.0 Ecore metamodel provided by BPMN2 project
obtained from http://git.eclipse.org/c/bpmn2

- A part of SCA 1.0 Ecore metamodel generated from XSD metamodel provided by osoa.

Here my simple code ATL:

-- @path sca=/BPMN2SCA/metaModels/sca.ecore
-- @path bpmn2=/BPMN2SCA/metaModels/bpmn2.ecore

module BPMN2SCA;
create ExampleSCA : sca from ExampleBPMN : bpmn2;

rule DefinitionsToComposite {

from
col: bpmn2!Definitions

to
com: sca!Composite(

)
}

My SCA Ecore metamodel:

<?xml version="1.0" encoding="UTF-8"?>
<ecore:EPackage xmi:version="2.0"
xmlns:xmi="http://www.omg.org/XMI"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:ecore="http://www.eclipse.org/emf/2002/Ecore" name="sca">

<eClassifiers xsi:type="ecore:EClass" name="Composite">
<eStructuralFeatures xsi:type="ecore:EAttribute" name="name" ordered="false" lowerBound="1"
eType="ecore:EDataType http://www.eclipse.org/emf/2002/Ecore#//EString"/>
</eClassifiers>
</ecore:EPackage>

My simple BPMN 2.0 example:

<?xml version="1.0" encoding="ISO-8859-1" standalone="yes"?>
<semantic:definitions id="_1275488606936"
targetNamespace="http://www.trisotech.com/definitions/_1275488606936"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:di="http://www.omg.org/spec/DD/20100524/DI"
xmlns:bpmndi="http://www.omg.org/spec/BPMN/20100524/DI"
xmlns:dc="http://www.omg.org/spec/DD/20100524/DC"
xmlns:semantic="http://www.omg.org/spec/BPMN/20100524/MODEL">
</semantic:definitions>

I just want to make a first step, is something wrong in my ATL code ? because I get an empty output SCA file like this:

<?xml version="1.0" encoding="UTF-8"?>

Thanks a lot for your help

Alex

This seems to be an empty model, so you obtain a corresponding empty SCA
model, no ??

First, Thank you for your reply.

Yes it's an empty BPMN Model, but I have an ATL code which transform a Definitions to a composite.I supposed to obtain an SCA model like this

<?xml version="1.0" encoding="UTF-8"?>

<composite xmlns="http://www.osoa.org/xmlns/sca/1.0" >

</composite>

Thank you for your cooperation

ATL executes rules on "matched" elements. If you have an empty model,
ATL does nothing at all, implying you get an empty XMI file.

I'll modify my BPMN model and I'll keep you posted.

Thanks.

The xmi file isn't empty, it contains one "definitions" element.
Look carefully :

<semantic:definitions id="_1275488606936" ...></semantic:definitions>

hello,

It's right, I have one element 'definitions' in my BPMN model that's why I am not supposed to obtain an empty SCA.

Normally, I must obtain an SCA model as an output file:

<?xml version="1.0" encoding="UTF-8"?>

<composite xmlns="http://www.osoa.org/xmlns/sca/1.0" >

</composite>

I posted my problem on MDT forum hoping to resolve it.

Thanks for your cooperation

Alex
