Hi all,
let's assume I have the following two file formats:
INPUT - Plain XML
As an input I've got a plain XML file. The language structure is
described with a given XMLSchema. From this I can derive an Ecore
meta-model by using EMF's import function.
OUTPUT - XMI
For the output I've defined my own domain-specific language with Ecore,
which is roughly 1-to-1 equivalent to the input language, but was
cleaned up a bit. As usual, instance of this meta-model are saved by EMF
in XMI format.
GOAL
Now I would like to convert a given plain XML file into the XMI format
which is an instance of my handcrafted ECore-Metamodel.
QUESTIONS
* Can I do this by using ATL?
* Is ATL able to read plain XML files, if I've got a corresponding
XMLSchema and (use EMF to) generate an equivalent Ecore-Metamodel
from it?
* If no, do you have other suggestions?
Thanks for any hints or comments,
Goetz

Yes, you can do that using ATL (and we have already done that many
times). The process is composed of two different steps:
1 - Inject your XML document into an XML model (i.e. a model which
conforms to the XML metamodel) -> this can be automatically done
right-clicking on your XML document using the AM3 Resource Navigator
view provided with the AM3 plugins available in the ATL downloads
(http://www.eclipse.org/m2m/atl/download/).
2 - Write an XML2XXX ATL transformation with XXX your target metamodel
Note that you don't need your XML schema.
