Hi,
my company is evaluating Sirius as dsl-editor tooling.
Metamodels and models
Currently our models are defined in xsd schemata and our model instances are defined in xml. See the attachment for an simplified example and the description of the example at the end.
Sirius Proof of concept
As a proof of concept I converted the xsd schema to an ecore metamodel and for a part of our models I implemented visualization examples with sirius.
In our proof of concept I instanciated new model instances and created elements via the sirius editor. So far so good - everything works fine.
What does not work
I tried to open (*1) our productive model instances in Sirius, but had problems with XIncludes in the xml files.
(*1: First I renamed the file extensions of the existing productive model xml files to the corresponding model file extension).
For exception stacktrace see next post.
What does work
When I replace the XIncludes in the existing xml model instances with the actual content of that include, it works!
Question
- How can I solve this problem without gluing the model instances into one big model?
- Our models are separated into multiple schemata and corresponding model instances.
-- As far as I can see this is just a logical and physical fragmentation of the model into several files, but they are all glued together in one (big) model file again, which xincludes all other models.
- During our evaluation phase of Sirius I wan't to stay compatible to the existing xsd schemata and xml model instances of our productive code. So it would be nice if I could tweak something on the sirius side instead
Information about provided example
- BigModel: includes all other (root) models (A and C); is the one we use at the end
- ModelA: some root model; includes ModelB
- ModelB: provides some more context to ModelA
- ModelC: another root model

Hi,
This is more of an EMF question than a Sirius one. In the stack you posted, this is your own ScenarioEditor that loads the model, not Sirius (which does not appear anywhere in the stack). I assume this is the one generated by EMF, maybe with some customizations.
EMF has its own ways to physically split models into seperate files (via controlled resources and inter-resources references using proxy URIs if you want to dig into this), but I am not sure EMF's XSD support handles Xinclude.
One possible approach (completely untested) would be to use EMF's support for passing configuration parameters to the underlying XML parser (see org.eclipse.emf.ecore.xmi.XMLResource.OPTION_PARSER_FEATURES) and enable XInclude by specifying http://apache.org/xml/features/xinclude (see https://xerces.apache.org/xerces2-j/features.html#xinclude). This means you'll need a custom Resource implementation to override the default load/save options to add these parameters.
Regards,
