Controlling eSuperTypes URI in XMI Serialization [message #431891]

Hi,

I am serializing an ecore model generated dynamically. (I am not sure if
this is even relevant)

For the resource I set the URI to model/instance.ecore which is relative to
my project in Eclipse.

When I lookin the file I see eSuperTypes="model/instance.ecore#MyClass" even
though MyClass is defined as an EClassifier in the same file.

I am wondering why the serialization needs to include the whole relative
path. It causes trouble when I load the model with different relative paths.
I presume I need to have relative path agnostic URIs and I should somehow
tell the serialization not to do this or to use the NS URI of the file
containing the EClassifier. However, my current situation seems to represent
the trivial case since the EClassifier is contained in the same file.

What is the right why to address this issue? I would think any kind of
relative path would not be good.

Thanks
Derek

Derek,

Be sure that the URI of every Resource is always absolute. E.g.,
platform:/resource/project/model/instance.ecore.
