[BPMN2] Using the BPMN2 editor XML as input for ATL [message #606547]

Hi all,

I'm defnining a transformation in ATL, which uses the BPMN2 metamodel as source.

I'd like to use the output XML from the BPMN2 editor as input for the ATL transformation. This does however not work. The output XML from the editor looks like this (conforming the BPMN2 xsd schema):

<?xml version="1.0" encoding="UTF-8"?>
<bpmn2:definitions xmlns:bpmn2="http://www.omg.org/spec/BPMN/20100524/MODEL-XMI" id="sid-Definitions">
<bpmn2:process id="sid-Process">
<bpmn2:startEvent id="sid-StartEvent">
<bpmn2:outgoing>sid-SF1</bpmn2:outgoing>
</bpmn2:startEvent>
<bpmn2:task id="sid-Task">
<bpmn2:incoming>sid-SF1</bpmn2:incoming>
<bpmn2:outgoing>sid-SF2</bpmn2:outgoing>
</bpmn2:task>
<bpmn2:endEvent id="sid-EndEvent">
<bpmn2:incoming>sid-SF2</bpmn2:incoming>
</bpmn2:endEvent>
<bpmn2:sequenceFlow id="sid-SF1" sourceRef="sid-StartEvent" targetRef="sid-Task"/>
<bpmn2:sequenceFlow id="sid-SF2" sourceRef="sid-Task" targetRef="sid-EndEvent"/>
</bpmn2:process>
</bpmn2:definitions>

This does conform to the BPMN metamodel, however, this is not excepted by ATL, because "definitions", "task", etc. ain't classes defined in the metamodel (rather they are attributes). A valid XML format accepted by ATL is the following:

<?xml version="1.0" encoding="ISO-8859-1"?>
<xmi:XMI xmi:version="2.0"
xmlns:xmi="http://www.omg.org/XMI"
xmlns="platform:/resource/Cent2Decent/BPMN.ecore">

<Definitions id="Process1" xmi:id="Process1">
<rootElements xmi:type="Process" id="sid-Process" name="Process1" xmi:id="sid-Process">
<flowElements xmi:type="Task" name="Task1" id="sid-Task1" xmi:id="sid-Task"/>
<flowElements xmi:type="StartEvent" name="StartEvent" id="sid-StartEvent" xmi:id="sid-StartEvent"/>
<flowElements xmi:type="EndEvent" name="EndEvent" id="sid-EndEvent" xmi:id="sid-EndEvent"/>
<flowElements xmi:type="SequenceFlow" name="SF1" id="sid-SF1" sourceRef="sid-StartEvent" targetRef="sid-Task1" xmi:id="sid-SF1"/>
<flowElements xmi:type="SequenceFlow" name="SF2" id="sid-SF2" sourceRef="sid-Task1" targetRef="sid-EndEvent" xmi:id="sid-SF2"/>
</rootElements>
</TDefinitions>

</xmi:XMI>

Is there a way to switch between the two representations? Or is there a way to load the first XML file directly in ATL?

Hi Pieter,
thanks for trying out the BPMN2 project.

What version of the BPMN2 editor are you using? Did you get it directly from our repository? If so, when?

I'm asking because the XML file is not 100% ok, the namespace for bpmn2 should be http://www.omg.org/spec/BPMN/20100524/MODEL (without the -XMI), and this should be the behaviour of our current version.

Could you change the namespace manually (remove "-XMI" from it) and retry the transformation?

Regards,
Henning

Hi Peter,
the MDT BPMN2 project supports both official file formats: XML (accrording to the OMG schema) and XMI (according to CMOF Metamodel).
The editor by default saves in XML format, as we consider it to be used more frequently. However, the editor has a "Save as" functionality. "Use File->Save as" and enter a file name with ".xmi" extension - then the file will appear in XMI format.
The code that does the conversion is rather simple - quoting now from BPMNEditor.java:

protected void doSaveAs(URI uri, IEditorInput editorInput) {
if (uri.toString().endsWith("xmi")) {
Resource oldResource = editingDomain.getResourceSet().getResources().get(0);
XMIResource newResource = new XMIResourceImpl();
editingDomain.getResourceSet().getResources().add(newResourc e);
newResource.setURI(uri);
List<EObject> content = new ArrayList<EObject>(oldResource.getContents());
for (EObject eObject : content) {
if (eObject.eClass().getName().equals("DocumentRoot")) {
newResource.getContents().addAll(eObject.eContents());
} else {
newResource.getContents().add(eObject);
}
}
oldResource.unload();
editingDomain.getResourceSet().getResources().remove(oldReso urce);

} else {
(editingDomain.getResourceSet().getResources().get(0)).setUR I(uri);
}
setInputWithNotify(editorInput);
setPartName(editorInput.getName());
IProgressMonitor progressMonitor = getActionBars().getStatusLineManager() != null ? getActionBars()
.getStatusLineManager().getProgressMonitor() : new NullProgressMonitor();
doSave(progressMonitor);
}

Hi all,

I'm defnining a transformation in ATL, which uses the BPMN2 metamodel as target.
how can I generate the namespace for bpmn2 in the target diagram ?

Thanks in advance!

Hello Ivannal,

could you elaborate on your problem? The mapping of namespace http://www.omg.org/spec/BPMN/20100524/MODEL to a prefix, normally bpmn2, should be generated automatically for the root element (definitions). Does this not happen in your case? What does the output of your transformation look like?

Regards,
Henning

Hello Henning,

I'm defnining a transformation in ATL, which uses the upcolbpip metamodel (a UML Profile) as source and the BPMN2 metamodel as target.

The first rule is:

module Rules;
create OUT : bpmn2 from IN : upcolbpip;
-- Crea los diagramas basicos
rule diagrams
{
	from collaboration : upcolbpip!UPColBPIPModel

	to definitions : bpmn2!Definitions
	(
		name <- collaboration.name,
		exporter <- 'Eclipse',
		exporterVersion <- '3.6'
	)
}

The output is:

<?xml version="1.0" encoding="ISO-8859-1"?>
<bpmn2:definitions xmlns:bpmn2="...omg.org/spec/BPMN/20100524/MODEL" id="_M2SWENsOEeCrqNqK_G9yTQ" exporter="Eclipse" exporterVersion="3.6" name="VMI model example"/>

Why do it generate Quote:

/>

instead of Quote:

</bpmn2:definitions>

?

how can I generate this?:

<?xml version="1.0" encoding="UTF-8"?> 
<bpmn2:definitions  
      xmlns:bpmn2="...omg.org/spec/BPMN/20100524/MODEL"  
      id="id1"> 
</bpmn2:definitions>

P.S. I can not use links because I sent less than 5 messages.

Thanks in advance!

Hello Ivanna,

why do you want to explicitly generate a closing tag instead of an empty-element tag, both being semantically equivalent? Note that your preferred version will be generated as soon as you have some child elements to the definitions element.

I'm not aware of any options that control this behavior.

Regards,
Henning
