Representing QVT-Operational transformations in XML, JSON or or any other serialized format [message #1856288]

I need some way to represent the QVT-Operational transformations in a json, xml or any other serialized format. In model to model transformation performed using operational QVT in eclipse, I am able to generate a trace file in XML format. The trace file provides details on which element in the source model is mapped to which element in the target model but I also require the transformation logic. So is there any way to either convert the QVT-operational file to xml(or any serialized format) or get transformation details in the trace file ?

Hi Antony

There is a hidden, experimental builder option named internal.save.xmi that makes the QVTo compiler generate *.qvtox files automatically.
To do so, the .project file of your QVTo project should look somehow like this:

	<buildSpec>
		<buildCommand>
			<name>org.eclipse.m2m.qvt.oml.project.QVTOBuilder</name>
			<arguments>
				<dictionary>
					<key>internal.save.xmi</key>
					<value>true</value>
				</dictionary>
				<dictionary>
					<key>src_container</key>
					<value>transforms</value>
				</dictionary>
			</arguments>
		</buildCommand>
	</buildSpec>

Kind regards
Christopher
