Dear all,
I want to summarize some important fact in model to model transformation.
You can say Am I all right?

The M2M project provides a framework for model-to-model transformation
languages. Transformations are executed by transformation engines. There
are three transformation engines that are developed in the M2M: ATL, QVTO,
QVTR.
QVTO - Declarative QVT (Core and Relational)is developed by Obeo. Does
Acceleo use this transformation?
QVTR - Operational QVT (Procedural)
ATL - is a QVT-like transformation language and does not cover all the
spectrum of QVT.

It will be continue...

I guess you mixed this up. QVTO ist Operational QVT (procedural).
Relational QVT and Declarative QVT provide the opposite. Please note,
that the OMG QVT Specs propose both, so in a sense all these are QVT.
There is a visual QVT as well (at least in theory).

In fact ATL existed before QVT, but QVT is an OMG Standard.

But there are even more Eclipse based model transformation engines:

-Epsilon Transformation Language (ETL):

-oAW Xtend:

Dear Mahdi,
according to QVT I have some opinion so you will say as Am I all right:
One one hand we have QVT as a standard, and on the other we have tools
that use some transformations to provide for example M2M transformation.
Some of these tools implements QVT standard, but either not.
QVT standard provide 3 languages:
1.Operation
2.Core
3.Relation.
Which Eclipse component implements this QVT languages? Is the correct when
I say
QVT Operation lanaguage implements QVTO.
QVT Relation lanaguage implements ????
QVT Core lanaguage implements ???
What's happened with Declarative QVT under Eclipse platform?
Can we use UMLX for this propose?
I found http://download.eclipse.org/modeling/m2m/qvt_declarative/upd ates/
that this language implements QVT Relations language.
But implementation of QVT Core I didn't find?

Best regards
D.Savic

Right, you need to differentiate M2M and M2T Transformations.

Yes, some try to implement (parts of) the QVT standard.

Please check this link for details:
http://en.wikipedia.org/wiki/QVT

Well maybe this is a writing mistake nd you mean the right thing. QVTO
is an implementation of QVT Operational and so on. The wiki link above
links to some other tools like mediniQVT or smartQVT for QVT Relational.
QVT Core forms the basis for the languages and is not really meant to be
directly used (as far as I understood it).

> What's happened with Declarative QVT under Eclipse platform?

Not sure if you are referring to this project here?
http://wiki.eclipse.org/M2M/Relational_QVT_Language_(QVTR)

Maybe someone else can comment on this.

Actually it is another concrete syntax for the QVT Relations Language.

The M2M/QVT Declarative project aims to support both QVTr and QVTc.

Currently the editors, parsers and models exist for both.
The QVTr executor is in very preliminary status.
The QVTc executor is pending.

>> What's happened with Declarative QVT under Eclipse platform?

It got renamed to QVT Drclarative.

UMLX cannot currently be used for anything. My progress on this enhanced
QVTr graphical language is very slow since there are numerous OCL, QVT and
Model issues that I have been working on instead.
