Dear modeling community,
The Declarative QVT is happy to announce you that a first build of
Declarative QVT is available.
You will find it at:
http://download.eclipse.org/modeling/m2m/qvt_declarative/upd ates/
Declarative QVT currently provides an implementation of the OMG MOF2
Query/View/Transformation (QVT) Relations language.
It is able to transform model thanks to a definition of relations that
should exist between the meta-models elements.
If you want to know more about QVT, you can browse the official
specification at http://www.omg.org/spec/QVT/1.0
In order to make you able to quickly test it, we provide a "Quick Start"
Document at http://www.eclipse.org/m2m/dqvt/quick_start.pdf and an
example project at
http://www.eclipse.org/m2m/dqvt/org.eclipse.qvt.declarative. example.umlToRdbms.zip.
Really more to come with a better coverage of the specification and even
the QVT Core language support... Keep in touch.
Regards,
Quentin

Hello,
Answers below:

> but maybe an existing post already exists what is the future for ATL ?
No, but here is an overview of the future of ATL (in large):
- We are currently working on a refactoring of ATL implementation, in
order to better support integration, maintenance, an extensibility.
Those works will be available on the next ATL release (synchronized will
the Eclipse Galileo simultaneous release).
- This work will allow us to provide some new improvements:
* ui improvements: ATL editor, errors management
* in place transformation
The main idea of those work is to keep intact ATL syntax and features,
to match industrial requirements.

I don't think there is need to use both in parallel.
As they are both transformation languages, they quite have the same
scope, and same functionalities. At this time, the main difference
between them is the syntax, and the fact that QVT conforms to an OMG
standard.
Best regards,
William Piers

Hi william
Thank you for your answer i was just surprised that obeo works both on
ATL and declarative QTV

Here are some other points to understand:
- We "believe" in the ATL syntax as it is pragmatic, readable way to
define transformations. So we want to keep improving tooling around.
- QVT Declarative is currently executed and compiled using the ATL
virtual machine.
- As standard conformance is one of the main industrial requirements, it
is very important for ATL to be oriented towards a QVT compatibility,
and QVT Declarative is the part of QVT which is the most complementary
with ATL.

Hello,
I have a problem with the Run-Configurations: I can create a "Declarative
QVT Transformation" and run it. I also can re-run the transformation, by
using the "Run As..." button (with the "Play"-icon). But if I go to the
Run-Configurations Dialog again, I always get a NullPointerException (for
detailed information look at the end) and the Information I entered for
the configuration is gone. I have to delete the entry and create it once
again.
I am using Ubuntu Linux and Java 1.6 Update 7.
java.lang.NullPointerException
