| UML2OWL transformation gives error [message #93539] |

A bit of background:
I have downloaded and installed the Eclipse Modeling Tools distribution of
Eclipse, which includes ATL 2.0.1.
Then, I downloaded the UML to OWL transformation from here:
http://www.eclipse.org/m2m/atl/atlTransformations/#UML2OWL
My goal is to go from UML to an OWL file (the XML representation). This
is a two step process using the UML to OWL transformation. The first
transformation takes the UML (in XMI format) to an OWL ecore model. The
second transformation takes the OWL ecore into the OWL XML representation.
I am testing this using the Museum example that comes with the UML to OWL
transformation.
I am able to transform the Museum.uml file to Museum-OWL.ecore file--or at
least it does not give me any error messages. When I look at the .ecore
file everything seems okay, although I'm not sure what kind of errors I
would look for. It is certainly well-formed XML and appears to be a valid
ecore model.
Then, I attempt to do the transform from Museum-OWL.ecore to Museum.owl.
I am doing this by creating a "Run Configuration" in Eclipse. The
metamodels are:
Source: /UML2OWL/OWL/OWL.ecore
Target: /UML2OWL/AMMACore/XML.ecore
However, when I run the transformation, I get the following stack trace.
Can anyone help?

The presence of the .atl file is not necessary since there is an .asm
file. As you can see in the build.xml, this is the .asm that is called and
not the .atl. And I think you can also use the launch configuration with
an .asm file (if not i will add the .atl file to the project), but i
recommend you to use the ant script.

This problem is surely due to the .project file. Try creating a new
UML2OWL project in your workspace. Then copy metamodels, transformations
files and build.xml in this new project. So the compilation process should
work fine again.

Hi Rocky,
I've updated the UML2OWL project
(http://perso.univ-lr.fr/ghillair/projects/UML2OWL.zip), so now there is a
new version for the OWL metamodel, update in UML2OWL.atl file and i've
added the OWL2XML.atl file.
Concerning you're problem with the build.xml, you need to install AM3 for
ATL developers (see http://wiki.eclipse.org/AM3/How_Install_AM3_From_SVN)
so you can use specific am3 ant actions. You also need AM3 for the
serialization of the XML model (created by OWL2XML.atl) into a plain xml
file (owl/xml format).
Best Regards,
Guillaume.
