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.
