Hi All,

I would like to experiment model transformation technologies. ATL, actually.

My ultimate goal is to create a sequence diagram using Papyrus diagram, then, to use
ATL to produce a state diagram model. The final step is to convert the obtained diagram into Papyrus format for visualization.

My Question is : how to obtain (grammatically, or with an existing tool) an ecore model from a Papyrus model i.e., .di ?

I need that because ATL takes an ecore model as input.

Thanks a lot.

Hello,

You should not try to convert a Papyrus model to an Ecore model. You should use the UML.ecore metamodel instead.

For your transformations, you should work with *.uml files (ie. the semantic files), which conform to the UML.ecore Metamodel. You can also work with notation.ecore (from ) + *.notation files for your diagram visualisations, although it is probably a lot more complicated (*.notation files are not trivial at all).

UML Metamodel (semantic): http://www.eclipse.org/uml2/4.0.0/UML (UML.ecore, from org.eclipse.uml2.uml)
Notation Metamodel (diagrams): http://www.eclipse.org/gmf/runtime/1.0.2/notation (notation.ecore, from org.eclipse.gmf.runtime.notation)

Hi Camille,

I managed to transform the .notation file by using metamodel from http://www.eclipse.org/gmf/runtime/1.0.2/notation. However, some elements are not in that metamodel. It looks like they form UML metamodel. Therefore, I cannot transform them to the output model. Do you know how to resolve this problem?

For example:
I need to transform this to the output model.

<element xmi:type="uml:Activity" href="Test.uml#_LmLfQHeIEemfZ8m9ot-iOA"/>

Thanks.

Hi

Do not dump on old threads. Your question may share the keywords UML and Ecore but is totally different.

I wrote a reply, but have deleted it to avoid polluting this thread with speculation about an impossibly vague question. e.g. what tool, what initialization, what activation?

Regards

Hi El,

I try to use ATL to transform multiple Activity diagrams into one Activity diagram.

I can transform the .uml file; however, I not sure which is the right approach to generate the diagram (or .notation file).

I tried with Diagram template plugin, but the diagram is not generated properly. The ControlFlow links are not displayed, some elements are duplicated...

Therefore, I tried another approach which transforms the .notation file as well.
I managed to fix the <element> node problem by allowing inter-model references. I also not sure if it is the right way to fix it. I am still new to Model-driven engineering, Papyrus, ATL...

Thanks.

I think that it is not a good solution to generate diagram with ATL. the notation model has to respect a structure of element. I think that is it is better to create programmatically a diagram then drop UML element inside diagram. see example :https://git.eclipse.org/c/papyrus/org.eclipse.papyrus.git/tree/tests/junit/plugins/uml/diagram/org.eclipse.papyrus.uml.diagram.clazz.tests/test/org/eclipse/papyrus/uml/diagram/clazz/test/canonical/TestDropfunction.java
