Converting output XMI file to XML [message #513309]

This may be a dumb question, but I am asking it because my boss wants the output of our model to be in XML instead of XMI. I do not know why? I thought that XMI already was an XML type file.

I have taken a UML diagram from model to RCP stand-alone app using Eclipse. Of course the changes in the model are stored as XMI files when we run the app. Is there any way I can change this output to XML? I know I could write a program to convert if necessary, but is there something along the path inside Eclipse from EMF model to RCP stand-alone where XML can be selected as the desired output format?

It seems like I saw something once that said "Ecore to XML". Is that what Ecore to XML does?

Thanks,

What does your boss think is the difference between an XMI file verses
an XML file? It presence of xmi:version="2.0" and
xmlns:xmi="http://www.omg.org/XMI" in the root element is the only
difference.

Well it definitely is XML already as you've observed.

I think your boss might be confused. You should ask him some skill
testing questions about the different between XML and XMI. See if he
gives the same answer as above.

It helps with migration when the serialization changes significantly
between versions of the same model.
