Hello,

Please, ask your future ATL-related questions on the
eclipse.modeling.m2m newsgroup. As a matter of fact, ATL has moved from
the GMT to the M2M project.

I added the eclipse.modeling.m2m newsgroup in copy of my answer, so that
you can directly reply to this message.


To answer your question:

You can automatize the process of extracting an Ecore metamodel to a KM3
file using either of these two main options:
- using an ant script (preferred method, see:
http://wiki.eclipse.org/index.php/AM3_Ant_Tasks),
- using Java code calling the KM3Projector class of the KM3 plugin.

To do things that the EMF2KM3.atl (i.e., Ecore-to-KM3) transformation
does not do yet (e.g., primitive types mapping), you can modify the
EMF2KM3.atl file available from:
http://www.eclipse.org/m2m/atl/atlTransformations/#EMF2KM3


Do not hesitate to contribute your modifications using Bugzilla.
Such a contribution to this very same transformation has already been
made (see: https://bugs.eclipse.org/bugs/show_bug.cgi?id=156446).


Regards,

Frédéric Jouault

Hello,

Going further in my work (my transformation seems to works in M2M with
an ATL launch configuration), I have tried the ant task method as
recommended but I have problems in writing the "build.xml".

1)How to adapt the launch configuration given for the EMF2KM3 example
(especially how to properly write the "am3.loadModel" for both metamodel
which are, in my case Ecore and KM3) ?

2)how to manage injectors and extractors through ant tasks ? More
precisely, what are the requirements to get a km3 file as a result ? I
am thinking about a km3 extractor but does it already exists or do I
have to design one? Ad so far, how to make a right reference to it ?
(giving solely one name in the "extractor" tag seems strange to me, so
do I miss something ?).

Best regards,
Quentin.

Hi Éric,

In fact, my problem is that, despite the help of the examples of the
wiki article, I can't get my ant file working because of problems during
the "loadModel" stage.

Actually everything goes nice while using the a launch configuration
(Run as...) with metamodels set to Ecore (#EMF) and KM3 (by uri) but
things break down when adapting to the ant file process:

- I downloaded KM3.ecore and Ecore.ecore.
- their am3.loadModel seems to be OK since there is no problem reported
in the console.

But when dealing with with the input model, I get errors that seems to
be due to its syntax (problems with double slashes that make prune one
character). So I made a try by removing double slashes : no improvement.
The input model is one made by EMF means (pure Ecore).

Is there a trick with model handler in the launch configuration that
should be done in the ant file?

Thanks a lot

Quentin

I join as attachments a build.xml and his configuration file which works
directly for the project taken from the Zoo
(http://www.eclipse.org/m2m/atl/atlTransformations/#EMF2KM3).
Just copy these files after importing the project (EMF2KM3 from the Zoo)
into your workspace.
You can delete or save the Sample-KM3.ecore before launching the ANT
script to ensure the generation is really performed :-).

OK, thanks to your example file, I managed to make it work. I was
missing the knowledge about the nsUri attribute which completely solved
my problem.

This option confers a relevant declaration. ;-)

Thanks a lot...
