I write you because I've a question I asked in the BPMN 2.0 Modeler Eclipse Forum and they suggest me to put the question here.
I'm new in BPMN2, EMF and ATL and I begin working with ATL transformations from BPMN 2.0 to other languages.
My metamodel is the file (.ecore) with the BPMN20 specifications of the official site (http://www.omg.org/spec/BPMN/2.0/) and my model XMI file is:
I don't generate that model (.XMI) with BPMN they supply me like a part of my project. The XMI-model has not packages, then I don't need to register the XMI-model? In fact, when I right-click in the file the option for that, no appears.
I've problems when I run the transformations. And I've the next error: "value of TargetNamespace is not legal".
I've send a topic to the ATL forum and they, first suggest me to open with the Sample Reflective Ecore Model Editor to check
the validity of my XMI file. Then when I open with this editor I've get the next error: "org.eclipse.emf.ecore.xmi.PackageNotFoundException: Package with uri 'www.omg.org/spec/BPMN/20100524/MODEL-XMI' not found."
and I've always the same error, when I open with the Sample Reflective Ecore Model Editor.
Anyone knows if there is a solution for the problem related with this issue or if it's other the problem I have?
Pherhaps I have to register other metamodels?, or I have to install new software in Eclipse, new XML, ATL packages, ...???? What registrations I need in order to read instances? Maybe I need a specialized resource implementation as part of my project?
