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.

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)
> Can we use UMLX for this propose? I found

> But implementation of QVT Core I didn't find?
Maybe someone else can comment on this.
