Hi everyone !

Here is my goal : I've got a lots of data in xml (automatically generated, i can't modify its structure), and i want it under my self defined emf metamodel.

I also have the xsd grammar from my xml files.

My problem is that i'm not really familiar to EMF and EMF tools, so i don't know what i can do to achieve my goal.

I suppose that i have to use my xsd to make a ecore metamodel, and then a model to model transformation, to get my data in my own metamodel, am i right?

Any hint or links is welcome.

Thanks !

You've followed the tutorial for producing a model from a schema?

Is your model very different from the model you get from the schema?

Hi Ed !

I followed a tutorial and i got my .ecore file from my xsd, and that was really easy.

Where i got some "problem" is to transform my xml data (following the xsd structure) in a model following the .ecore file generated.

And yes, the final model i need is clearly different than the generated, but it seems there is some model to model transformation tool.

In fact, i don't even know if converting my raw xml data into an ecore model is possible, or better than parsing the xml and building a model myself.

What specifically is the problem?

I'm not familiar with the model transformation tools. Of course you can
always write such a transformation in Java using the generated APIs for
each model

With enough effort, almost anything is possible.

Certainly you can deal with transforming either SAX events, a DOM
structure, or an EMF schema-based representation into your final EMF
representation. Probably the final one is the easiest to write while
the first will perform the best.
