OMG XMI to Eclipse UML or to Ecore - best option? [message #1785610]

Hello,

I have an OMG XMI file from https://www.omg.org/spec/SBVR/20160601/SBVR-XMI-Metamodel.xml .

If I want to make it into a Eclipse UML2 (XMI) file (.uml) or into an Ecore (XMI) file what are my best options?

Do I need to write a QVT transformation from OMG UML XMI to Eclipse UML XMI and then to ecore XMI? Or is there some other way such as open the OMG XMI in Papyrus and export as Ecore or Eclipse UML (if that is possible)?

Regards,
Bruce

Hi

On a really good day you can open with the UML Model Editor and save as *.uml.

On a good day you can manually rename to a *.xmi file.

On a less good day you need to rename to *.uml, and to use a text editor to adjust the namespaces to match another *.uml file.

Hi

From the changed question on the Papyrus newsgroup...

The actual problem was the failure to load a CMOF file with an unexpected version combination. See https://bugs.eclipse.org/bugs/show_bug.cgi?id=533703

The actual fix is to use a text editor to adjust the versions/namespaces to match a supported *.cmof file.

Hi Ed,

Thanks.

My question now is what are my options to convert the cmof XMI file I know am able to load in the UML editor, into Eclipse UML XMI (so that I can then do a convert to Ecore)? On the loaded XMI it still has cmof tags and so the "Convert to:" does not recognize the package element and so become enabled. In other words, I would like to go from CMOF XMI to Eclipse UML XMI to Ecore XMI. Should I just go QVT or is there an easier way?

Regards,
Bruce

Hi

Open in the UML Model Editor. File->Save As... and specify something.uml

Hi Ed,

Ok. Thanks. I just tried that. Got an interesting result:

the resulting .uml file looks like modisco got in there:

<?xml version="1.0" encoding="UTF-8"?>
<modisco.xml:Root xmi:version="20131001" xmlns:xmi="http://www.omg.org/spec/XMI/20131001" xmlns:modisco.xml="http://www.eclipse.org/MoDisco/Xml/0.1.incubation/XML" xmi:id="_n_ADwELeEeiKM9CtD28VzA" name="xmi:XMI">

</children>
....

Do I need to uninstall modisco?

Hi Ed,

Following Kenn's point in https://bugs.eclipse.org/bugs/show_bug.cgi?id=533703 to rename the file as .xmi gives me some trouble when I open with the UML editor.

I right click on the SBVR-XMI-Metamodel.xmi file and open with UML Editor and get the follwing problems:

org.eclipse.emf.ecore.xmi.PackageNotFoundException: Package with uri 'http://schema.omg.org/spec/MOF/2.0/cmof.xml' not found. (platform:/resource/TestSBVR/model/SBVR-XMI-Metamodel.xmi, 3, 97)

...

This worked for you?

Hi

You probably have multiple options for Open With... Make sure you use the UML Model Editor. I suspect that Modisco is attempting to do model recovery on a generic extension.

If you need to uninstall Modisco, then raise a Modisco Bugzilla. If with hindsight the Modisco editor is too prominent in the list of editors, maybe something can be done. There is now a "default" that can be set and is now used to ensure that the Sample Ecore Editor dominates the OCLinEcore Editor. Perhaps the same declaration is needed to ensure the UML Model Editor dominates the Modisco or TextUML editors. Could work for *.uml/*.cmof but for *.xml/*.xmi the anarchy may bes unavoidable.

Hi

*.xmi worked fine for me this morning, but I'm pretty sure it didn't yesterday. This probably means something has remained open.

The UML/Ecore Model Editors use an EditingDomain so that multiple editors can share the same edited model. Perhaps we both have a bad editor still open when trying the next permutation.

Next time *.xmi does not work for you close all editors/debuggers/... and open the *.xmi again. If that still fails restart Eclipse... If there is something genuinely bad we need a repro.

Hello,

I can get the .xmi version to load into UML2 Model Editor and then Save As... .uml file and that works fine and then I can open that with UML2 Model Editor and select package and convert to Ecore. That works.

Just curious, when I use the extension .cmof, the load into the UML Model Editor complains of packagenotfound:
org.eclipse.emf.ecore.xmi.PackageNotFoundException: Package with uri 'http://schema.omg.org/spec/MOF/2.0/cmof.xml' not found. (platform:/resource/TestSBVR/model/SBVR-XMI-Metamodel.cmof, 3, 97)

I used the debugger enough to find out that the packageregistry for the XML resource is empty. What plugin in supposed to register something for .cmof files?

Regards,
Bruce

Hi

That looks like the repro I was looking for but couldn't reproduce. Please double check that it fails in a clean escape, then attach the exact file.

Hi,

Yes. I think this is a good repro of the problem.

I download a clean stock eclipse modeling download package
eclipse-modeling-oxygen-M2-macosx-cocoa-x86_64.tar.gz

Created a simple project and add the attached cmof file to it.

Right click on that file and Open With... UML Model Editor

I see a failure to open with a PackageNotFoundException with Package with
uri http://schema.omg.org/spec/MOF/2.0/cmof.xml not found.

Regards,
Bruce
