Hey there!
I need to access emf model which is shown in tree structure for ATL transformation. The emf model is generated from TEXTBE tool whose language is made in emftext. Now the the TEXTBE tool takes textual input and as a result shows the tree like structure of the model but i am unable to find its xmi dialect.
How can i access xmi model ??
ANy help

Whether the resource contains text, XML, or whatever, the same
mechanisms are used.

I know nothing about that, so I can't answer questions about it.

Some of those I know, and some I don't.

Likely using EMF's resource framework.

I see.

That's an ATL question, not an EMF one.

I don't think that's true. I think it will use EMF to load a resource
for the specified URI and you can register a resource factory for
dealing with URIs of that form, e.g., register a factory based on
extension, and then the resource will be loaded by the right
implementation that can read the appropriate format.

Yes, but I would hope that you read some basic reference material that I
suggest and not come back and explain how pointless it is. You'll need
to learn about resource set, resource, and so on. There's a nice book
you can buy. But if you come and say "I no nothing, please explain
everything to me" that's just not going to work well.
